$ glxinfo | grep direct

And here is my xorg.conf part:

EndSection

Section "Extensions"
   #Option "Composite" "Enable"
EndSection

What can I do to get reasonable performance? A very old NVIDIA card I used
to have 5 years ago could achieve 10000 fps with those old NVIDIA drivers
when running glxgears in very old hardware like Pentium4 2.4 GHz and default
depth 16.

Cheers,
Panos.
