Slow OpenGL on 7.3
I installed the Nvidia 2960 drivers for my TNT 1. I read the readme.txt and all the libraries seem to be correctly installed. I can run KDE fine and there is an Nvidia splash screen when I start it now. Unfortunately, my OpenGL screensavers don't work at all and when I run Quake 3, it runs at about 1 frame every 5 seconds. What could be wrong? How do I check to see that q3demo is using the right GL drivers? (when i use "ldd" on q3demo, it says it's not a dynamic executable). Here is a paste of what q3demo says when it is starting up:
----- R_Init -----

I fixed the problem... at least for Quake 3. Basically I had to edit /etc/X11/X11Config to include lower resolutions like 640x480, 800x600, etc. The problem was that since these video modes weren't listed in the X11 config file, Quake 3 used the Mesa OpenGL (software) instead of the Nvidia OpenGL. Now it's running smoothly. I haven't tried other opengl application yet.
