SYMPTOMS
If you use the True Color (24-bit) color mode in Windows, the number of frames per second (FPS) that are displayed on the screen may be reduced (as compared to other color modes).



CAUSE
This behavior occurs because 24-bit DirectDraw is not supported by most video adapter drivers. The 16-bit and 32-bit modes are faster, and are typically recommended over 24-bit mode.



RESOLUTION
To resolve this issue, first try changing the color mode in Windows:
 * 1) Right-click a blank area on the desktop, and then click Properties.
 * 2) In the Display Properties dialog box, click the Settings tab.
 * 3) In the Colors box, click High Color (16-bit) or True Color (32-bit).
 * 4) Click OK.

If the High Color (16-bit) or True Color (32-bit) setting is not available in the Colors box, your video adapter driver may be outdated. Contact the manufacturer of the video adapter to inquire about obtaining an updated driver.
