sRGB is a standardized color space for use with monitors, printers, and the internet. It is supported by OpenGL and Direct3D.

The r_shader_srgb ConVar determines whether sRGB conversion is done through hardware or through software.

• -1: Use hardware cap^[Clarify]
• 0: Use hardware sRGB conversion (Default)
• 1: Use software sRGB conversion

Note: The  Xbox 360 will always use hardware conversion.

There is also a fallback shader srgb that can be used in VMTs to detect whether or not conversion is actually being done through hardware.
