im using fc6 x86_64, have Version: 1.0-9629 and i run glxgears at 15000fps and opengl things -work- but when i try an run quake 3 it doesn't go into full screen, just stays in a window, but it runs fine at constant 125fps, so i'm guessing it's an issue with the latest drivers _sigh_ (and i have load glx in the module section in xorg.conf)
here's a link to my xorg.conf, can't see anything that is wrong
