slow Nvidia graphics

I'm getting slow graphics on my nVidia system and I can't figure out why. I'm getting these numbers from
Quote:
$> glxgears
4476 frames in 5.0 seconds = 895.030 FPS
4408 frames in 5.0 seconds = 881.434 FPS
4651 frames in 5.0 seconds = 930.001 FPS
5761 frames in 5.0 seconds = 1152.103 FPS
7254 frames in 5.0 seconds = 1450.671 FPS
7244 frames in 5.0 seconds = 1448.692 FPS
7692 frames in 5.0 seconds = 1538.254 FPS
7574 frames in 5.0 seconds = 1514.779 FPS
My system has given me good performance in the past, but I couldn't say which update(s) may have done it as I've just been running 'yum update' the last month or so. I have a nVidia 7600 GS. I get no 'WW" or "EE" from the Xorg.0.log and /var/log/messages and dmesg show no errors or warnings either. System loads show nothing
more than a few % here and there.

I'm running the latest bits:
kernel-2.6.24.3-34
nvidia-kmod-169.12-3.lvn8 nvidia kernel modules built for kernel 2.6.24.3-34.fc8

Could my xorg.conf file be somehow off the end? Check for sanity, please?

Are you running any kind of compositing engine? IE: compiz, compiz-fusion, berl.

glxgears is NOT a benchmark tool, just a crude test of DRI. The fluxuation in your FPS indicate that the system is under load from another source.

I understand that - I posted the output just to show the fluc not having anything else to show, other
than 'my systems sucks" when I play games.

I had the compiz desktop effects running. I shut those down and things run much better.
Funny they didn't show up as producing a load on the system anywhere else, just slowing
down graphics terribly.

Thanks for the tip!

The desktop effects are loading down the GPU, which is not monitored, not the CPU....
