Hi Bob,
that's about right. If you want the best 3D performance then you need a
native driver for NVIDIA cards. I believe ATI cards are already supported
in the distributed drivers, other cards I have no idea about I'm afraid.
The fallback when no native GLX is available for your graphics card is to
install the Mesa package driver. That does software rendering.
You can test if GLX is working by running the "glxgears" command (a score
of a few thousand FPS seems to be sufficient).
Cheers,
Peter.
