I decided to pull my Voodoo 2 out of the SS7 machine (it needed some cleaning) and play with the Riva128ZX. I have the RIVA128-3.37W9xAGP.ZIP drivers installed for it. Every time I change the graphics mode to either 3DNow! OpenGL or Default OpenGL, Quake 2 reverts back to software 800x600. Is there a magic trick or something else I need to install?

Ok figured out the problem. Windows desktop was set to 32bit mode so Quake 2 was trying to get the Riva128ZX into 32bit mode when initializing. Changing the Windows desktop to 16bit mode and rebooting resolved the issue.

Getting 32.6 FPS on time demo map1 using 3DNow! OpenGL and 1576 with 3DMark99 on a K6-2+ 550 which is a very similar to a Voodoo 2 running on 1x TMU. Very happy!
