NVidia - Frames Per Second


I recently upgraded to Mandriva Linux 2006. It seems like everything is a bit choppier. I installed the nvidia drivers and after running glxgears, it shows 694 FPS. Is this average for a NVidia GeForce2 MX440 card?

glxgears
1061 frames in 5.0 seconds = 212.200 FPS
1141 frames in 5.0 seconds = 228.200 FPS
1169 frames in 5.0 seconds = 233.800 FPS
1126 frames in 5.0 seconds = 225.200 FPS
1157 frames in 5.0 seconds = 231.400 FPS


That's on a Geforce 2 GTS Pro (64MB), which i thought was a better model than the MX.. maybe not

glxgears is not a very good benchmarking program to compare cause it depends on what size/resolution it is and of course color depth.
here is output when i change it's size
Code:
3623 frames in 5.0 seconds = 724.600 FPS
4981 frames in 5.0 seconds = 996.200 FPS
2837 frames in 5.0 seconds = 567.400 FPS
1895 frames in 5.0 seconds = 379.000 FPS
651 frames in 5.0 seconds = 130.200 FPS
perhaps show your x config and the output from
cat /proc/mtrr
and x log

remember too that bad kernel throuput = bad performance for everything

I am not sure where the X log is. Could you tell me how to find it.
