I am using an ATI card, but this may help anyway. I found that
3D hardware acceleration only worked for 16bpp. Early versions of
Quake3 would force a shift to 16bbp from my usual 24bpp. Descent 3
would not force the shift and I was using Mesa (OpenGL in software).
By getting out of X Windows and restarting in 16bpp, the hardware
acceleration worked. Versions of Quake3 < 1.30 were stable (didn't
crash X) when used as the X client, i.e., no window manager or desktop
environment. With Quake3 1.30, running it as the X client doesn't
work. I haven't tried running it from 24bpp X session, yet.
HTH,

I've got a Matrox Millenium II AGP card. The 7.3 setup seemed to recognize it and the normal video display is fine, but I've noticed that when I try to run various games that (presumably?) use 3D functionality - things like the flight simulator and the Tron racing game - the display is unusably slow (it seems to build a frame every 10s or so!).
Is my card just too old to cope with new fancy graphics, or have I perhaps set something up wrong? I've tried playing with SAX2, ticking boxes in the "3D Settings" at random (in ignorance), but with no improvement.
If it helps, one 3D game is fine. I think it is called Descent iirc. Perhaps this uses different display technology?
Any help appreciated.
