In directdraw is the Pixel format for 32 bit surfaces always the same ??
If I click on the DirectX icon in the Control panel I can see that the format for 16bit is shown for each resolution but it is not for 32 bit..
Didn''t quite understand you''re question but perhaps this can help. 32 bit color should be the same for all. It is divided into four 8 bit sections for red, green, blue and alpha. You''re video card may have constraints performance or otherwise as to what color depth it can display at resolution x, but the actual pixel format of that color depth should be the same regardless.
