How do I enable the so-called 22-bit color feature on the Voodoo3?
A. Just go in the Advanced Options in the 3DFX Tools, and set 3D Filter Quality to High and Alpha-Blending to Sharper. If you are using Pa3PyX’s driver, instead of changing 3D Filter Quality (cuz it’s not there), you need to change Image Filtering Mode to 2×2. It’s the same, only that it’s under a different name. Note that all of these features need to be change separately in each video mode (D3D and OpenGL/Glide) and also note that it won’t exactly “dramatically increase image quality”, only slightly, and in some games can give visual defects.
