Pre-Requisites for Good CRT Simulation
Most discrete GPUs work (Radeon, GeForce, Arc).
Some fast mobile GPUs work (iPhone 120Hz with “Prefer Page Updates Near 60fps” turned off).
Recommended: 240 Hz OLED
Minimum: 120 Hz LCD (non-FALD, due to local dimming lag)
Fantastic: 360-480 Hz OLED
Display ideally configured to SDR mode (LCD or OLED).
This is because the current formulas used in the shader (gamma2linear and linear2gamma) is expecting the ability to calculate a photon budget for brightness-spreading over multiple refresh cycles for brightest pixels. This lowers persistence of average brightness pixels, and brightens the CRT simulation significantly. If you do any HDR boosting, you may need to readjust the GAIN_VS_BLUR constant and the GAMMA constant until banding disappears.
