Logicamente los filtros consumen, cierto, como modificaciones graficas que son, por lo tanto, desactivarlos aquellos que sufrais "relanti" en los juegos.
Os recomiendo dejar la opcion de mame.ini en AUTO o bien en GDI, notareis perdida grafica pero ganareis velocidad, eso ya depende del equipo que tengais. Os dejo una captura de donde se modifca eso exactamente:
No os fijeis en lo que esta marcado, eso es para otra cosa que aproveche la imagen, lo que os interesa es la opcion VIDEO, os dejo un copy/paste del manual oficial en mamedev de las opciones posibles y la expliacion:
Core Video Options-video <bgfx|gdi|d3d|opengl|soft|none>
Specifies which video subsystem to use for drawing. Options here depend on the operating system and whether this is an SDL-compiled version of MAME.
On Windows:
Using ‘bgfx‘ specifies the new hardware accelerated renderer.
Using ‘gdi‘ here, tells MAME to render video using older standard Windows graphics drawing calls. This is the slowest but most compatible option on older versions of Windows.
Using ‘d3d‘ tells MAME to use Direct3D for rendering. This produces the better quality output than gdi and enables additional rendering options. It is recommended if you have a semi-recent (2002+) video card or onboard Intel video of the HD3000 line or better.
Using ‘none‘ displays no windows and does no drawing. This is primarily present for doing CPU benchmarks without the overhead of the video system. The default is d3d.
On other platforms (including SDL on Windows):
Using ‘opengl‘ tells MAME to render video using OpenGL acceleration. This may not work on all platforms due to wildly varying quality of stack and drivers.
Using ‘soft‘ uses software rendering for video output. This isn’t as fast or as nice as OpenGL but will work on any platform.
Defaults:
The default on Windows is d3d.
The default for Mac OS X is ‘opengl‘ because OS X is guaranteed to have a compliant OpenGL stack.
The default on all other systems is ‘soft‘.
Y para quitar los filtros si los habeis puesto, pues es aqui, poniendo a 0 la opcion GL_GLSL_FILTER, siempre entendiendo que poneis como VIDEO OPTIONS OPENGL, que es para este modo los filtros que puse.
