There's your problem, DRI (Direct Rendering Infrastructure) is not enabled. When you run
Code:
glxinfo
or the fglrx-equivalent, you should get a message telling you DRI is enabled and the name of the driver; the driver name should Not be Mesa-something if you're using (for example ATI's) fglrx drivers, or nvidia's official drivers; Mesa is an open source driver and probably doesn't get the best out of your card. Without DRI enabled with the correct drivers for your card you obviously can't get good fps, because no 3d accelaration is used that your card should. There are quite a lot of posts and threads here explaining how to install ATI or nVidia (or other?) drivers, how to get DRI working etc. so please use the search tool at the top of the page to discover them.

Just so you know the difference it makes in 3d acceleration
Code:
[shrikant@shricore64 ~]$ glxgears
43528 frames in 5.0 seconds = 8705.303 FPS
43809 frames in 5.0 seconds = 8761.651 FPS
43809 frames in 5.0 seconds = 8761.619 FPS
43829 frames in 5.0 seconds = 8765.746 FPS
43895 frames in 5.0 seconds = 8778.933 FPS
43835 frames in 5.0 seconds = 8766.816 FPS
43967 frames in 5.0 seconds = 8793.363 FPS
43129 frames in 5.0 seconds = 8625.718 FPS
X connection to :0.0 broken (explicit kill or server shutdown).

i tried to add "Section"DRI"
Mode 0666
EndSection"

but there is no effect on 3d acceleration...
