I had no problems with my nvidia card in mandrake 10. I just upgraded to 10.1 yesterday and glxgears is slow as balls. Almost like the problem i had with my old ATI cards. Don't tell me that Nvidia is going ATI's route now. If you need anymore info just let me know. And thanks

Heres what glxgears gives me

1154 frames in 5.0 seconds = 230.800 FPS
981 frames in 5.0 seconds = 196.200 FPS
1260 frames in 5.0 seconds = 252.000 FPS
974 frames in 5.0 seconds = 194.800 FPS
851 frames in 6.0 seconds = 141.833 FPS
281 frames in 5.0 seconds = 56.200 FPS
401 frames in 6.0 seconds = 66.833 FPS
405 frames in 7.0 seconds = 57.857 FPS
405 frames in 6.0 seconds = 67.500 FPS
270 frames in 7.0 seconds = 38.571 FPS
269 frames in 6.0 seconds = 44.833 FPS
270 frames in 5.0 seconds = 54.000 FPS
270 frames in 5.0 seconds = 54.000 FPS
270 frames in 5.0 seconds = 54.000 FPS
270 frames in 6.0 seconds = 45.000 FPS

Try reinstalling the driver. Normally the kernel is changed during an update and the NVIDIA module stops working. Try urpme NVIDIA and then reinstall...

another mistake is not checking to see if the nvidia module is loading. run lsmod, if its not there then do modprobe nvidia. double check your XFree86 or Xorg.confg file to make sure its loading nvidia and not nv.
