you should run glxgears to see what your fps is. it would also tell you if you're using software rendering or not.

GLX gears is a pretty unreliable benchmark: I've gotten anywhere from 300 to 600 FPS on this machine at different times. I usually get around 90 FPS when playing fairly recent games like Modern Warfare 2 (on windows). Perhaps you meant glxinfo, which reports whether direct rendering is enabled (and it is).
