I find that very bad, with a GeForce 7800 GTX, I get with glxgears 24bbp:

-default resolution of glxgears which is about 300x300 pixels.
- Full screen is 1280x1024.

SuSE 10.1 64 bits Digital entry : 300x300 -> 16606 fps 1280x1024 -> 3410fps
SuSE 10.1 64 bits Analog entry : 300x300 -> 16791 fps 1280x1024 -> 3383 fps
SuSE 10.1 32 bits Digital entry : 300x300 -> 15710 fps 1280x1024 -> 3410fps

My monitor is an DFP EIZO Flexcan L778 with digital and analog entries.

Michel.
