I will list as many reliable servers here as I can find. Note that this recommended hardware list may differ slightly from others, as it is based on practical experience with playability. A PC Computer with a Pentium 133 processor or better. This is the preferred platform for GLQuake as it is the best consumer end 3d accelerator with the right combination of features and speed currently available. The Voodoo Rush is currently a suboptimal chipset due to driver problems.
Performance is unacceptable.
Note that the 3Dfx OpenGL driver which comes with GLQuake is only a partial port of OpenGL, implementing only the functions necessary to run GLQuake. 3Dfx is working on a full OpenGL port. NEC has delivered a working OpenGL miniport to testers. It's not up to Voodoo par, but this is a valid chipset for GLQuaking, and later releases of the miniport are bringing it closer and closer. Plus, you CAN do 800x600.
