OpenGL Quake - Quake II
Quake II and III can use other OpenGL implementations beside 3Dfx
Voodoo. To date, there are only three types of hardware acceleration
supported by Linux - 3Dfx Voodoo cards, nVidia Riva cards (128, TNT,
TNT2, etc.), and Matrox G200 and G400 (experimental).
You have to tell Quake II what type of rendering to use. See the command-line options for an example of
how to do this.
