This sample application illustrates the three stages in the DirectX 9 graphics pipeline at which gamma correction can be applied:

1. From 2.2 to linear upon texture read (for supported formats)
2. To 2.2 on frame buffer write (on devices which support it)
3. Through arbitrary gamma table on scan out to DAC (universally supported)

sRGBTest Controls

• S - Toggle D3DRS_SRGBWRITEENABLE

• [F2] - Prompts user to select a new rendering device or display mode
• Alt+[ENTER] - Toggles between fullscreen and windowed modes
