I am running Windows Vista x64, with a core 2 duo and an 8800 GTS G92.

Occasionally while playing, I get a white screen and a popup notifying me about how the Nvidia OpenGL display driver has stopped working. I also get the same problem if I click "Apply now" in the graphics settings.

I get this problem using both nexuiz.exe and nexuiz-sdl.exe.

If anybody has some advice on how to play the game without it crashing, I'd like to hear it.

Try installing a new version of the nvidia drivers.
