RTG AMD: Inciativa GPUOpen software stack [su contra gameworks]

1, 2, 3
Una iniciativa [esperemos no se quede en eso, como es costumbre de AMD] del RTG [radeon technology group] de juntar a los desarrolladores de consola y los de PC en un solo 'ecosistema', para unos permitirles exprimir al maximo el APU y su GPU GCN, y a los otros a dejar de pensar a la PC como 'caja negra', y regresen al estilo 'clasico' de desarrollo del software/juegos para aprovechar la potencia bruta de la PC.

Para esto, RTG invita a la iniciativa 'GPUOpen software stack', que sera tener codigo, ejemplos de este codigo y en si toda la documentacion necesaria para entender el funcionamiento del GPU GCN, esto como codigo de software libre y con repositorio en GitHub para que cualquiera pueda acceder, ademas de proveer de bibliotecas y kits de desarrollo SDK, en estos momentos segun entiendo su prioridad es usen TressFX y LiquidVR, por lo que viene en todos los SDK actuales y futuros.

Creo que este tipo de acciones es lo que requiere AMD para meterse mas en el mercado, pero antes debe limpiar su mala imagen de 'muchas intensiones y pocos resultados', que es de lo que se quejan muchos desarrolladores en la falta de apoyo y respuestas a sus dudas sobre X o Y funcionalidad del hardware grafico, y tendria que 'comprometerse' a realomente apoyar a estas personas ofrecuiendo siempre respuestas y motivandolos a ultilizar X o Y funcion, no solo para juegos, sino para el ambito multimedia y otros menesteres.

Ah, y dentro de esta iniciativa, un objetivo es reanimar el desarrollo para GNU/Linux, y esperemos volver a tener esos titulos AA de juegos en GNU/Linux aparte de los de Valve/Steam.

Y un fruto de esta iniciativa es Vulkan, el cual de paso este año ya tiene las reglas definitivas u oficiales para comenzar a usarlo. Por esta razon AMD por fin confirma que sacara controladores con la nueva API VULKAN, el pero es que por ahora aparecera solo para GNU/Linux y solo estara disponible para los controladores oficiales Radeon DRM. Posteriormente lo tendremos bajo windows.

AMD escribió:[..] our Linux Vulkan drivers will only run on the amdgpu kernel driver. We have no plans, on Linux, to support Vulkan on any other driver stack


Aun no se estaba seguro que modelos de tarjetas estaran soportadas en estos controladores para permitir el uso de la API Vulkan, y especulaban que podrian ser solo para las de GCN 1.2. Por suerte tras comunicarse Phoronix les han confirmado que estara disponible para todos los GPUs GCN [1.0 al 1.2]

http://www.phoronix.com/scan.php?page=n ... -To-AMDGPU
Our user mode Vulkan driver supports all GCN parts starting from 1.0 (Southern Islands). We use an identical user-mode component on Windows and Linux (compiled for the appropriate target of course). The differences are minimal – window system stuff, and some abstractions of system level things like mutexes and shared memory.

Lo dividen para dos grupos:
* Games & CGI. Desarrolladores de software de juegos y de software de modelado 3D y renderizado.
* Profesional comput. Desarrolladores que quieran usar la acelaracion por GPU.


AMD escribió:GPUOpen is based on three principles:

The first is to provide code and documentation allowing PC developers to exert more control on the GPU. Current and upcoming GCN architectures (such as Polaris) include many features not exposed today in PC graphics APIs, and GPUOpen aims to empower developers with ways to leverage some of those features. In addition to generating quality or performance advantages such access will also enable easier porting from current-generation consoles (XBox One™ and PlayStation 4) to the PC platform.

The second is a commitment to open source software. The game and graphics development community is an active hub of enthusiastic individuals who believe in the value of sharing knowledge. Full and flexible access to the source of tools, libraries and effects is a key pillar of the GPUOpen philosophy. Only through open source access are developers able to modify, optimize, fix, port and learn from software. The goal? Encouraging innovation and the development of amazing graphics techniques and optimizations in PC games.

The third is a collaborative engagement with the developer community. GPUOpen software is hosted on public source code repositories such as GitHub as a way to enable sharing and collaboration. Engineers from different functions will also regularly write blog posts about various GPU-related topics, game technologies or industry news.
Podria ser que Hitamn sea un titulo beneficiado de este GPUOpen, usando Compute Asyncronous, eyefinity mejorado y otras tecnologias graficas de AMD

GPUOPen ¿habra sido el detonante de que nvidia liberara el codigo de gameworks?

http://www.elotrolado.net/hilo_nvidia-l ... ks_2160137

Algunos piensan que si, y que seria la forma de acallar las tantas quejas que ha recibido nvidia por parte de las desarrolladores, las cuales veian a GameWorks como 'la caja negra' [no sabes que hay dentro, ni que es lo que exactamente hace] en su proyecto de juego, y que por tanto, no podian realizar algunas optimizaciones o cambios de codigo hasta que estuviera siendo usado por los jugadores, y salieran los errores. Esperemos ea para bien nuestro.

Volviendo al tema de GPUOpen, parece que AMD sera un colaborador mas que cercano [o mas de lo que ya venia siendo de hace años], para la optimizacion de la API grafica D3D12, ya que desde ahora, el desarrollador del juego tendra un papel mas determinante en el rendimiento final dependiendo del hardware. AMD junto con otros desarrolladores estara apoyando a Microsoft con la mejora y evolucion del lenguaje de programacion HLSL, que es el usado para crear los shaders D3D, donde quitaran algunas instrucciones y meteran otras mas acordes al nuevo hardware, y tambien se reorganizara la estructura de como se escribe para hacerlo mas rapido y logico.

Otra cosa en la que ayudara es en la parte del nuevo modelo 'Shaders 6', vinculado directamente a esto del lenguaje HLSL, donde podria crearse alguna herramienta que ayude a optimizar y compilar el codigo mas eficiente para cada fabricante del GPU, es decir, un codigo especifico para las AMD Radeon y otro codigo mas especifico para las nvidia geforce, lo que aligeraria mucho del trabajo del programador.

Lo anterior de codigos especificos para Radeon Y geforce es necesario en D3D12, ya que cada arquitectura hace algunas cosas de diferente manera, ademas de cada una tiene sus cualidades y defectos, por ejemplo, Radeon esta mas optimizado para shaders de computo de uso general y computo asincrono, pero es malo para el tesselado, mientras geforce es lo contrario.

Aqui un ejemplo, despues del ultimo parche para el juego God of Wars: Ultimate Edition, el cual agrega shaders especificos para Radeon y shaders especificos para Geforce, notamos un cambio radical en el rendimiento de las radeon, que ahora se equipara y a veces sobrepasa a la geforce.

La queja de los programadores, es que realizar este codigo especifico D3D12 para cada marca de GPU les llevara mas tiempo, entre escribirlo, probarlo y depurarlo. Con GPUOpen y con los SDK de Microsoft [y shaders 6] esto no pasaria.


Lo que me pregunto es si tambien AMD apoyara a el Grupo Khronos, con este proyecto GPUOpen para hacer lo mismo con Vulkan, donde me imagino que tambien se requerira de codigo de shaders Vulkan especifico para Radeon y para Geforce.
Aparece un Compilador que permite portar [interpretar] las instrucciones usadas en CUDA llevandolas a OpenCL, con esto sera sencillo agregar soporte OpenLC a un codigo que emplee CUDA. El compilador permite emplear multiGPU, optimiza la administracion de la RAM/VRAM entre otras funciones.

GCN Shader Extensions for Direct3D and Vulkan


The GCN architecture contains a lot of functionality in the shader cores which is not currently exposed in current APIs like Vulkan™ or Direct3D® 12. One of the mandates of GPUOpen is to give developers better access to the hardware, and today we’re releasing extensions for these APIs to expose additional GCN features to developers.


En su ultimo informe de ganancias, Lisa Lu comenta que la demanda de la RX 480 es bastante buena y esperan lo mismo con las RX 470/460, asi mismo dice que se puede satisfacer la cantidad de las GPU requeridas por los fabricantes.


http://seekingalpha.com/article/3990485 ... transcript

David M. Wong - Wells Fargo Securities LLC
Okay. Great. Thanks, Lisa. And since the launch of your Radeon 480 graphics product end of last month, have you been able to supply to demand for the cards or if not, when do you expect demand will rise to match supply?

Lisa T. Su - President, CEO & Non-Independent Director
Yeah, so, David, we're very pleased with the launch of the Radeon RX 480. We had good supply at major retailers on launch day. Since then, the demand has continued to be strong and so some of the retailers are out of supply. We do see that the 14nm LPP yields are good and we are ramping up production steeply. So we expect that that will equalize as we go through the quarter. We are also very soon going to launch the rest of the Radeon RX family. And so you'll see three products in the third quarter in terms of overall product momentum.


Tambien en RTG esoperan mejorar el software de controladores y sus derivados.
RTG libera el kit de desarrollo y bibliotecas para TrueAudio_NEXT junto con el Advanced Media Framework, el primero para el trabajo de Audio y el segundo para tratamiento de video y audio en el GPU radeon.

GPUOpen escribió:TrueAudio Next

AMD TrueAudio Next (TAN) is a software development kit for GPU accelerated audio signal processing. As part of the LiquidVR™ technology initiative aimed at enabling a fully immersive and comfortable virtual reality experience, TrueAudio Next enables full real-time dynamic physics-based audio acoustics rendering.

TAN SDK Features
Fast OpenCL™ parallel batch convolution engine
Multi-threaded, multi-queue, real-time architecture
Extendable open source API
CPU and GPU implementations for all functions
Sample applications for GPU acceleration of Virtual Reality audio

Benefits
The TAN SDK provides real time audio applications the ability to leverage the OpenCL™ toolchain and to co-exist with graphics.
Accelerating VR game audio on the GPU frees CPU bandwidth for game physics and AI, while enabling advanced interactive acoustics modeling on many audio streams.
Virtual Reality audio has greatly increased compute requirements:
Conventional gaming audio rendering is only satisfactory for flat screen games
Quality of existing 3D positioning, attenuation and occlusion simulation satisfies the functional needs of FPS gamers
No expectation or even desire for “audio immersion” as it would not match the graphics experience on flat screens
Artificial, studio-derived models are used, and are sufficient for needs (audiophiles aside)
More realistic audio nice-to-have but not essential to the experience of a flat screen game
Virtual Reality demands Presence (Immersion, Suspension of Disbelief)
Presence requires all perceptual aspects including audio to simulate consensual reality
Audio approximations and artificial models break presence – no matter how good the HMD is
People instinctively know the difference between the auditory real world and rough approximations
Our ability to perceive reality through audio cues helped us survive and evolve – we are all audio experts
We don’t need to solve the problem of 3D audio using Head-Related Transfer Functions
This problem has already been solved for about 20 years and runs fine on today’s CPUs
Although necessary, 3D audio alone does not equal audio presence
Physics-derived audio benefits from real-time, time-varying convolution performed on every audio source. TAN Convolution leverages the power of the GPU to provide reliable time-varying convolution for many audio sources.
Most advanced audio algorithms depend on high-performance FFT or FHT (Fast Hartley Transform). The TAN library enables these algorithms to leverage the GPU.
The TAN library may be used in conjunction with Radeon Rays (formerly FireRays) as foundational accelerated algorithms for a complete physics-based audio solution.

GPUOpen escribió:The Advanced Media Framework

The Advanced Media Framework SDK provides developers with optimal access to AMD GPUs for multimedia processing. This SDK may be used in developing wireless display, remote desktop, video editing, transcode and playback applications. Specifically, developers can use the AMF SDK for accessing AMD media accelerators for video encoding and decoding and color space conversions.
Advanced Media Framework Benefits

The AMF SDK allows optimization of application performance by utilizing CPU, GPU compute shaders and hardware accelerators for media processing. These optimizations are applicable to a wide range of applications such as gaming or content creation. Programming of AMD Video Engines (UVD and VCE blocks) is also an important part of the functionality that AMF provides to developers.

Jeff Kampman, techreport.com escribió:AMD turns on multi-GPU frame pacing for DX12 titles

Here at TR, we've long considered multi-GPU rendering something of a false grail for graphics-performance scaling. Potent multi-GPU cards like AMD's Radeon HD 7990 and R9 295 X2 have tended to deliver world-beating average frame rates in our testing, but our Inside the Second frame-time measures usually put a big fat asterisk next to those cards' numbers. That's because issues with consistent frame delivery have often made those CrossFire-on-a-stick cards feel much less smooth in practice than their astronomical frame rates might suggest.

To get around this problem, Radeons include frame-pacing algorithms in their drivers to make sure that inter-GPU timing issues don't mess with smooth frame delivery too much. At least in the red team's case, that technology apparently wasn't available in DirectX 12 titles—at least until now. AMD tapped some guy from its performance-testing department to explain the technology and its benefits in an informative, concise video that's well worth a watch.

We haven't verified these results for ourselves yet—doing so would require use of an FCAT rig that I don't have set up here. Still, given our history, we're inclined to trust that AMD guy in the video above. DirectX 12 frame pacing for Radeons is available in the Radeon Software 16.10.1 release that hit the interwebs yesterday. If you've got multiple Radeons churning out frames in next-generation titles, you'll most definitely want to install that update post-haste.

Segun WCCF Tech RTG|AMD dejara de desarrollar el software 'Gaming Evolved APP' proximamente. Este software esta basado en el programa RAPTR, y que era la respuesta al 'GeForce Experience APP' de nvidia. 'Gaming Evolved APP' permite hacer capturas de video del juego, transmision en streaming y buscar configuraciones optimizadas para los juegos instalados.

Asi que para los nuevos controladores Crimson oficiales ya no veremos en las opciones de instalacion este programa 'Gaming Evolved APP'.

Anthony Garreffa, .tweaktown.com escribió:AMD to drop RX 470 price to $169 to battle GTX 1050Ti

Exclusive: AMD is preparing for a big fight against NVIDIA's purported GeForce GTX 1050 Ti which is expected to be unveiled and released soon, by dropping the price of their mid-range champion graphics card, the Radeon RX 470.

AMD launched the Radeon RX 470 at around $179, but will be dropping the price of the RX 470 by $10, with a fresh new price of $169, according to my industry sources. NVIDIA's GeForce GTX 1050 Ti won't match the speed of the Polaris-based Radeon RX 470, which will be 30% faster - and fully VR-ready (with more performance on the Oculus Rift, thanks to the latest updates unveiled from Oculus during their developer conference, Oculus Connect 3 last week).

NVIDIA is expected to price the GeForce GTX 1050 Ti at around $149, but it won't match the performance of AMD's Radeon RX 470 - and that's going to be a huge win for AMD in the mid-range market where 1080p monitors are dominant. 1080p 60FPS gaming at $159 with VR-ready goodness, and cheaper FreeSync monitors for AMD Radeon owners is a great thing for the 80% of the market AMD is targeting with Polaris.

Implementing LiquidVR™ Affinity Multi-GPU support in Serious Sam VR.

Introduction

Let’s say you’re in a store deciding which headphones to buy. You don’t want to spend too much money so you settle for a nice inexpensive wired pair with good sound but an inexpensive cable. Inevitably, the cable is damaged and you’re back in the store – you already spent money on this and you don’t want to break the bank on headphones. We all know how this ends. You end up purchasing the most expensive pair of headphones that you should have bought in the first place.
Short term development

Similarly, when you first need to add virtual reality rendering support to an existing game engine, you want to do it as quickly as possible just to be able to see the results and then decide where to go from there. You’d usually do this by simply rendering the entire scene twice with different matrices for each eye. The problem with this approach is that it results in bad performance because it doubles the draw calls, but on the other hand it gives you a correctly rendered VR scene without too much effort. The more efficient approach would be to render the entire scene in one pass.

Taking a single pass approach means we only run the rendering once per frame, for both eyes simultaneously, which significantly decreases CPU overhead. This is obviously what we want to have in the end, but the downside is that it’s often a lot harder to implement in an existing engine as it requires changing a lot of code.

We wanted to add LiquidVR Affinity Multi-GPU rendering support to our engine because two GPUs can render the two eye views in almost half the time compared to a single GPU and this would greatly reduce our GPU bottlenecks. Affinity MGPU can either be done in one pass or with a separate pass for each eye, in which case we reap the GPU side benefits while the CPU workload stays the same.

Required changes to our Engine

The root cause of the incorrect eye display was that our engine wasn’t affinity-aware – e.g. binding a texture on one GPU prevented us from binding the same texture on the other one because it was already marked as bound. Easy fix – just forget texture states after rendering each eye. Then we found out that we read from a surface that is empty on one GPU because we only rendered to that surface on the other one. This can be fixed by setting affinity to both GPUs before any render to texture that needs to be read on both GPUs.

We discovered many similar problems and we worked on this simple solution for a couple of weeks and actually managed to fix almost all of the rendering issues. This resulted in a solid performance boost in GPU bound scenarios, but we gained nothing in cases where we were constrained on the CPU. We would need to spend more time to find and fix the remaining rendering issues, so we decided to bite the bullet and move to single pass rendering.

Summary

We needed about a week to modify all shaders and to make sure that correct data is set for each eye. Single pass rendering with Affinity Multi-GPU gave us a huge speed improvement on both CPU and GPU from our original VR implementation. In the end, it took us less time to do single pass rendering correctly than it took us to fix all the problems caused by multi pass multi-GPU rendering.

The ROCm Platform bringing a rich foundation to advanced computing by better intergrating the CPU and GPU to solve realworld problems.

On April 25th, 2016, we delivered ROCm 1.0 built around three core foundation elements:

Open Hetrogenous Computing Platform (Linux(R) Driver and Runtime Stack) optimized for HPC & Ultra-scale class computing Heterogeneous C and C++ Single Source to better address the whole system computation not just a gpu device HIP acknowledging the need for platform choice when utilizing GPU computing API

Using our knowledge of the HSA Standards and, more importantly, the HSA Runtime we have been able to successfully extended support to the dGPU with critical features for NUMA class acceleration. As a result, the ROCK driver is composed of several components based on our efforts to develop the Heterogeneous System Architecture for APUs, including the new AMDGPU driver, the Kernel Fusion Driver (KFD), the HSA+ Runtime and an LLVM based compilation stack for the building of key language support. This support starts with AMD’s FIJI Family of dGPU, and has expanded to include the Hawaii dGPU Family in ROCm 1.2 ROCm 1.3 expands this support to include the Polaris Family of ASICS.


Radeon Open Compute Platform (ROCm) 1.3


At SC16, AMD (NASDAQ: AMD) today announced a new release of Radeon Open Compute Platform (ROCm) featuring software support of new Radeon GPU hardware, new math libraries, and a rich foundation of modern programming languages, designed to speed development of high-performance, energy-efficient heterogeneous computing systems. AMD also announced planned support of OpenCL™ and for a wide range of CPUs in upcoming releases of ROCm, including support for AMD's upcoming "Zen"-based CPUs, Cavium ThunderX CPUs, and IBM Power 8 CPUs. The advances further cement ROCm's position as the most versatile open source platform for GPU computing.

"Radeon Open Compute is a platform for a new era of GPU problem-solving, designed to harness the power of open source software to unlock new solutions for HPC and hyperscale computing," said Raja Koduri, senior vice president and chief architect, Radeon Technologies Group, AMD. "Today's release of ROCm gives developers consummate flexibility in where and how they use GPU compute. We're excited to show off some of these incredible applications at SC16."

"An open source approach to heterogeneous computing can help bring the benefits of high-performance computing directly to developers, providing the flexibility for them to use available compute resources and extract the best possible performance from their available hardware," said Denise Dumas, vice president, Platform Engineering, Red Hat. "As a leader in helping to nurture and maintain open source communities, we are pleased to see that AMD has elected to take a community-focused approach to ROCm."

"The combination of AMD's GPU support of ThunderX® along with the breadth of features of the ROCm software release is a valuable addition to Cavium's overall solution for the HPC and Hyperscale server market," said Larry Wikelius, Vice President of the Software Ecosystem and Solutions Group at Cavium, Inc. "Today's announcement by AMD is an excellent complement to the innovative features of ThunderX® that include 48 ARMv8 cores, integrated I/O and dual socket configuration support that our customers and partners are deploying today in these markets"

The new release of ROCm introduces a wide range of updates, including:
Expanded GPU support – ROCm now supports all Polaris architecture-based graphics products, including the Radeon™ RX 460, 470 and 480 graphics cards, and the Radeon™ Pro WX 7100, 5100 and 4100 GPUs, growing the rich portfolio of devices supported by ROCm devices. The Polaris architecture is specifically designed to benefit low-level programming, helping developers to extract the most from the hardware.
ROCm Virtualization of the GPU hardware via OS Containers and Linux®'s Kernel Virtual Machine (KVM) - ROCm now supports Docker containerization, allowing end-users to simplify the deployment of an application in ROCm-enabled Linux server environments. ROCm also supports GPU Hardware Virtualization via KVM pass-through to allow the benefits of hardware-accelerated GPU computing in virtualized solutions.
Heterogeneous Compute Compiler (HCC) – HCC is a single source ISO C++ 11/14 compiler for both CPU and GPU, with support for the C++17 "Parallel Standard Template Library". It is built on a rich compiler infrastructure including LLVM-based GCN ISA code generation with assembler and disassembler support.
Heterogeneous-Compute Interface for Portability (HIP) – HIP enables developers to port CUDA applications to ROCm using HIPIFY which automates the conversion to the HIP kernel language and runtime API, creating portable applications that can run on virtually any GPU using either NVIDIA's CUDA Compiler or HCC.
New Math Acceleration Libraries – ROCm introduces support for new advanced math acceleration libraries with support for BLAS, FFT and N-dimensional tensor contractions.

In addition to today's release of ROCm, AMD also announced that it is working to expand the ROCm ecosystem through increased server CPU support, and planned support of OpenCL. Upcoming releases of ROCm are expected to support AMD "Zen"-based x86 CPUs, ARM AArch64 CPU architecture starting with Cavium ThunderX processors, as well as IBM Power 8 CPUs and servers to meet customers' growing hyperscale and HPC needs. OpenCL is being built on a ROCm runtime and compiler foundation which give much greater low-level control of the GPU via its direct-to-metal access.

Forward Rendering

RTG muestra un 'nuevo' metodo de renderizado para mejorar el rendimiento en la VR, dando un menor frame time [tiempo que hay entre un fotogram,a y el siguiente] y con ello un video mas fluido, ademas, Forward Rendering ofrece mejores tecnicas de antialiasing y efectos luminosos mas espectaculares y realistas. Por ahora este metodo es soportradio por el motor Unreal y el motor Unity, pero RTG|AMD esta en comunicacion con otras casas desarrolladoras para que implementen el soporte a este metodo Forward Rendering.

AMD, Developers Embrace Forward Rendering in Unreal Engine 4 to Improve VR

Compromise. It’s something many VR developers today deal with in their ongoing quest to nail the right mix of technical features and computational power for the best balance of performance and visual fidelity. Many of today’s big game engines use a technique called deferred rendering. Deferred rendering does all of the geometry work first and then shades pixels.That worked well on the last generation of consoles, but it’s not a great fit for VR.

With the forward rendering path in Unreal Engine 4, developed by the amazingly talented engineers at Epic, developers have more choice in how they render for VR, helping to achieve a stunning-looking game while delivering the high frame rates necessary for a good experience.

Discussed on stage at AMD’s “Capsaicin” webcast and press event at the 2017 Game Developers Conference, the forward rendering path provides a strong alternative to the popular deferred rendering method, allowing developers to hit the demanding frame rates necessary for smooth VR experiences with improved image quality. Forward rendering has been showcased in games such as Epic Games’ Robo Recall, and is planned in upcoming VR titles from awesome developers like First Contact Entertainment, Limitless Studios, and Survios.

Technically Speaking: Deferred vs Forward Rendering

Let’s dig in and talk about this a bit. Deferred rendering has a performance cost for each frame, in addition to higher GPU memory and bandwidth requirements compared to forward rendering . While deferred rendering does support some nice features like screen-space reflections, those features are generally too costly to use given VR’s ~90FPS requirement.

Current head mounted display (HMD) resolutions being what they are, VR also really benefits from high-quality edge smoothing. Deferred rendering unfortunately doesn’t mix well with multi-sampled anti-aliasing (MSAA) because there are performance and image quality issues. But MSAA is arguably the best AA technique for VR. Post-process AA methods like FXAA don’t work terribly well with stereo views in VR. If you’ve tried a game that uses it, you know it doesn’t look good.

All told, AMD feels that deferred rendering exacts a toll in terms of time, memory, and image quality in VR, and the payoff just isn’t there.

The alternative here is to adopt a form of forward rendering. Interestingly, it’s not a new technique; in fact it’s how GPU rendering started. It’s lighter weight, simpler, and faster. Also, forward rendering works nicely with MSAA, letting us improve edge quality very efficiently. So we think forward rendering is often a better fit for VR applications.

We’ve worked diligently to test and optimize the forward rendering path in Unreal Engine 4.15 for the best performance on AMD hardware. A number of VR development partners are using Unreal Engine, and we showed the performance benefits during our Capsaicin event at GDC.

“AMD has been on a continuous mission to make VR accessible to as many people as possible, and Epic’s forward rendering path in Unreal Engine 4 is a big step in that journey,” said Raja Koduri, Senior Vice President and Chief Architect, Radeon Technologies Group, AMD. “Anyone who has experienced Epic’s Robo Recall will immediately attest to the benefit of forward rendering in VR. We are working with VR developers to explore the benefits of forward rendering, which can result in beautiful, high-performing games on Radeon graphics.”

Radeon ProRender: A free open-source, high performance, real-time physically based ray tracing engine capable of producing lightning fast, high quality renders. With plug-ins available for major 3D modelling and CAD software, this is easy to pick up. We find this is a good application for benchmarking the performance of your GPU.

Radeon Rays: A GPU intersection acceleration library with basic support for heterogeneous systems. AMD developed Radeon-Rays to help developers get the most out of AMD GPUs, CPU and APUs, as well as save them from maintaining hardware-dependent code. Radeon Rays exposes a well-defined C++ API for scene construction and performing asynchronous ray intersection queries. The current implementation is based on OpenCL, which means Radeon-Rays supports execution on all platforms conforming to the OpenCL 1.2 standard. It is not limited to AMD hardware or a specific operating system. Radeon Rays can be easily distributed and through its API helps assure compatibility and best performance across a wide range of hardware platforms.

Baikal Renderer: An open-source implementation of AMD Radeon ProRender (RPR). It is a fast and efficient GPU-based global illumination renderer implemented using OpenCL and relying on AMD’s Radeon Rays intersection engine

AMD distribuye controladores orientados a la minería de criptomonedas
por Adolfo hace 13 horas

Dos días ha tardado AMD en revelar sus cartas al lanzar una nueva versión de sus controladores enfocados en mejorar el rendimiento de sus RX 580 y RX Vega 64 y RX Vega 56 en tareas de minado de criptodivisas.

El éxito de AMD este año no se debe en forma alguna a los gamers, sino a los mineros, que han acabado con las existencias de RX 580 desde prácticamente desde su lanzamiento y que todo parece indicar que lo mismo ocurrirá con las RX Vega.

AMD sabe quién es realmente el público objetivo de estas nuevas GPUs y por ello, a pesar de lanzar revisiones de sus drivers Crimson Relive para jugadores, dedica grandes esfuerzos en mantener su reinado en el mercado que tantos beneficios les está reportando y donde Nvidia poco tiene que hacer.


..
Eso, distribuye drivers para minería y no tiene cojones a hacer un driver como dios manda para vega, y para jugar,
CON 2 COJONES!
Ya lo sacara, pero ahora esta en le recuento de los daños donde por la mala fama en juegos pero aceptable en minado, pues se aventura a sacar esta version BETA.

Ya para el lanzamiento de la VEGA 56 debe tener controladores CRIMSON decentes.
Pues ya es oficial, al termino de sus 'vacaciones' el indio Raja Koduri dejara su puesto de jefe de este departamento RTG y pasara a formar parte de la nomina de intel, como jefe del departamento 'Core and Visual Computing Group' que se encargara del desarrollo de GPU integrado para losp rocesadores intel de nueva generacion.

Beta 13: AMD TrueAudio Next Support

We have just released Steam Audio 2.0 beta 13, which brings support for AMD TrueAudio Next technology. TrueAudio Next lets developers accelerate certain spatial audio processing tasks by reserving a portion of the GPU. Combined with Steam Audio's ability to model a wide range of acoustic phenomena, this enables increased acoustic complexity and an increased sense of presence in games and VR applications. Click here[valvesoftware.github.io] to download the latest version of Steam Audio, or click here[github.com] to grab the source code for the Unity and FMOD Studio plugins.

[..]
How is TrueAudio Next useful to Steam® Audio?

Indirect Sound
Steam® Audio uses physics-based simulation to model two ways in which sound travels from a source to a listener. Direct sound is sound that travels in a straight line from the source to the listener, possibly passing through solid objects. Indirect sound is sound that is emitted from the source, bounces off solid objects repeatedly, and then reaches the listener.

Steam® Audio models indirect sound by calculating an IR using ray tracing. This IR is then used in a convolution reverb effect to add indirect sound effects to either individual sound sources (in the case of source-centric convolution reverb) or a submix of sound reaching the listener (in the case of listener-centric convolution reverb).

Simulating and rendering indirect sound is the most computationally intensive part of what Steam® Audio does, and TrueAudio Next helps manage this workload.

Ambisonics
Source-centric convolution reverb can be directional in nature: somebody else's distant footsteps heard through an open doorway sound more directional than one's own footsteps in a large room, for example. Steam® Audio uses Ambisonics to represent the directional variation of indirect sound. The higher the Ambisonics order, the more spatial detail that can be rendered in the indirect sound. On the other hand, the higher the Ambisonics order, the more IRs that are needed in the convolution reverb effect. For example, 2nd order Ambisonics requires 9 convolutions per source. This too, increases the computational cost of indirect sound.

Note that Steam® Audio does not use TrueAudio Next for applying HRTF-based 3D audio rendering. The computational cost of HRTF processing is significantly lower than that of convolution reverb: thousands of sources can be rendered with HRTF-based 3D audio using a single CPU core.

Why does Steam® Audio support TrueAudio Next?
Steam® Audio's existing CPU-based convolution has sufficient performance for many applications, particularly those that rely heavily on listener-centric reverb. However, with TrueAudio Next, Steam® Audio can offer more flexibility to developers.

There are two main reasons why we chose to support TrueAudio Next in Steam® Audio:

If we can provide developers with more flexibility in choosing how their audio processing workloads are balanced on a user's PC, we want to do that. TrueAudio Next allows developers to choose how CPU and GPU resources work together to provide a compelling audio experience on the user's PC.
If we can allow developers to offer an optional higher level of audio detail with their existing content on PCs that are powerful enough, we want to do that. With Steam® Audio, developers just specify higher settings to be used if a TAN-capable GPU is installed on the user's PC. Developers do not have to re-author any content to work with TAN. Steam® Audio can be used to seamlessly select either CPU- or GPU-based convolution, depending on the user's hardware configuration.

Steam® Audio's support for TrueAudio Next does not in any way restrict Steam® Audio to specific hardware or platforms. We hope that our support for TrueAudio Next encourages hardware and platform vendors to provide more options for developers to balance their audio workloads against graphics, physics, and other workloads, which in turn will help them create better audio experiences for their users.

PC Exclusive No More: FreeSync Finally Lands On Xbox One Consoles.
by Jason Evangelho

Variable refresh rate support is finally landing on Microsoft's Xbox One X and Xbox One S, but you may know it as a formerly PC-exclusive perk called FreeSync. Microsoft's Larry Hyrb and AMD's Antal Tungler announced the feature on Microsoft's Inside Xbox show today, and this is very good news for Xbox players.

This isn't a throwaway technical feature Microsoft is slipping quietly into the console. It's truly a next-gen gaming feature and a fundamental shift in how we play games.

When Project Scorpio's hardware specs were unveiled with HDMI 2.1 and Radeon graphics under the hood, we also learned that FreeSync 2 with HDR should be along for the ride, but it didn't materialize during the Xbox One X launch. Questions inside the Xbox community have been persistent, but answers were nowhere to be found. Today's reveal that it's also coming to Xbox One (FreeSync) and Xbox One S (FreeSync 2 with HDR) is a cool surprise.

Nvidia gets the official credit for transforming this landscape. When G-Sync was introduced for GeForce-owning PC players, it was the first time that our monitors weren't dictating the refresh rate. Traditionally a monitor wouldn't display a new frame until it was ready -- based on its refresh rate which is normally 60Hz. This resulted in seeing a "tear" and stuttering on the screen.

With G-Sync, the graphics card was now in charge, sending the frame to the monitor precisely when it was rendered. In a nutshell, that means no more screen tearing and no more "input lag" from using something like VSync. It results in a noticeably smoother, faster visual experience even at lower frame rates. It can even mean the difference between life and death in fast-paced shooters.

After G-Sync, AMD came along and introduced their version of variable refresh rate which, unlike Nvidia's solution, didn't require a proprietary module in the back of monitors. This made FreeSync monitors more affordable than their G-Sync counterparts. More importantly to Xbox One S/Xowners, it opened the door for this kind of game changer on consoles.

So think about the last game you played that was locked at 30fps. The Xbox One S and Xbox One X may be capable of delivering higher frame rates in that title, but perhaps not a full 60fps. 45fps would give you terrible screen tearing and stuttering, though, which is why so many games stay locked at 30fps or 60fps.

What FreeSync allows the system to do is synchronize directly with the monitor, and render the game at the framerate it's capable of because the FreeSync monitor isn't dictating the refresh rate. So perhaps the game now fluctuates between 40fps and 70fps depending on the visual complexity of any given scene, plus each frame looks smoother and is delivered faster because the monitor isn't in charge anymore.

Seriously, you need to see it for yourself. The first time I saw this technology in action it was like comparing the difference between VHS tapes and DVDs. Whether it's G-Sync or FreeSync, variable refresh rate gaming is truly next-gen, so it's a perfect fit for a next-gen console. And it's nice to see it leaving the exclusivity of PC for more people to enjoy.

FreeSync 2 with HDR for Xbox One S/X should be available in the Alpha Ring for Xbox Insiders within the next few days. Original FreeSync will be available for the standard Xbox One. You'll need a FreeSync-compatible monitor.

Announcing Real-Time Ray Tracing
by Dan Flatt

The level of visual detail required of CAD models for the automotive industry or the most advanced film VFX requires a level of visual accuracy that can only be achieved with advanced ray tracing techniques. Ray tracing maps the path of light rays from each pixel of the rendered object back to the camera, realistically simulating light interactions like shadows, reflections and transparency. Ray tracing is very processor intensive resulting in long render times and low frame rates. Alternatively, rasterization (or scanline) rendering uses algorithms to approximate the appearance of 3D objects, surfaces and textures. Rasterization can be accelerated by GPU hardware resulting in real-time rendering and high frame rates making it an ideal fit for gaming. Of course the trade-off with rasterization is that the approximated renders are nowhere close to the photorealism of their ray traced counterparts. These trade-offs between rasterization and ray tracing traditionally impose corresponding constraints on 3D designers who would have to choose between realistic illumination and real-time speeds depending on the priorities of their project.

The differences between rasterization and ray tracing at a computational level have made the combination of these processes a desirable but difficult problem discussed more often in academic papers than practical application. AMD is announcing Radeon™ ProRender support for real-time GPU acceleration of ray tracing techniques mixed with traditional rasterization based rendering. This new process fuses the speed of rasterization with the physically-based realism that users of Radeon ProRender expect for their workflows. At a high level, the process achieves these results by using rasterization to draw basic structures and surfaces before a ray tracing process is used to compute advanced light-effects like reflections, shadows and transparency. The flexibility of the process allows users to decide when these advanced light effects are actually necessary and add noticeable new dimensions of realism to their renders.

So how could real-time ray tracing actually change the way 3D professionals work? Professional users of this new process will be able to achieve far faster render times for their projects saving valuable time and system resources for 3D projects of any scale. Game developers will also be able to achieve a greater degree of photorealism without sacrificing the high frame rates required for smooth real-time onscreen animation. (We’ll talk more about how the new rendering technique can enhance gaming graphics in future blog posts.) Like many of the other open source tools available from GPUOpen, real-time ray tracing will give users more control over the development process unlocking even more performance from your GPU.

Access to real-time ray-tracing will be made available to AMD partners by contacting your AMD representative. You can learn more about the process in our session with Takahiro Harada at GDC on March 21 and stay up to date by signing up to receive the AMD Developer News newsletter.

Y parece que GCN aunque ya este empezando a mostrar 'achaques' sera una buena opcion para el tema de voxels, que seria una tecnica volumetica enl ugar de poligonos para el tema de la creacion de los mundos virtuales de los juegos.

Añaden Soporte a la reproduccion UHD por hardware de video para cuando se reproduce video desde Netflix. POR DESGRACIA el soporte esta limitado solo para usarse en el navegador Microsoft Edge.

Asi que si quieren contrar con este soporte deberan instalar el Controlador ADRENALIN 18.4.1.
PLAYRADY 3.0, almenos en version beta con soporte no solo a polaris, sino a VEGA con lo que ya es posible usar la decodificacion UHD de netflix en tarjetas de video VEGA y en los nuevos APUs Raven Ridge.

This will be a one-hour long event presented by AMD's Lisa Su and Jim Anderson. AMD promises to show off "never-before-seen" hardware demonstrations and details of high-performance leadership and innovation. Presumably, we're going to hear more about the second-gen Threadripper processors, and maybe mobile Vega discrete video cards. Everyone is hoping for some more GPU news, but I'm not holding my breath for that one.

Y RTG vuelve a la carga con su concepto de GPUs ompuestos de manera modular, asi en lugar de ser un solo gran chip, los sistemas y subsistemas se reparten en pequeños chips que se encapsulan segun las necesidades y tipo de tarjeta [si sera de gama media o gama alta, si sera mas para juegos o sera mas para computacion heterogenea, etc.]
