Then neither it is related to a recent rpm change.

You have hit the nail on an interesting point: it is not that the fps is 
low, but that the gears turn very slowly. In my previous tests in 10.1 I 
got:

>>  cer@nimrodel:~> glxgears
>>  3596 frames in 5.0 seconds = 719.072 FPS
>>  4023 frames in 5.0 seconds = 804.191 FPS

>>  652 frames in 5.0 seconds = 130.221 FPS


And that is similar to what I got in my recent tests in 9.3:


| cer@linux:~> glxgears 
| 4081 frames in 5.0 seconds = 816.200 FPS       windowed
| 4421 frames in 5.0 seconds = 884.200 FPS
| 4412 frames in 5.0 seconds = 882.400 FPS
| 4342 frames in 5.0 seconds = 868.400 FPS
| 2366 frames in 5.0 seconds = 473.200 FPS
| 611 frames in 5.0 seconds = 122.200 FPS        full screen
| 608 frames in 5.0 seconds = 121.600 FPS
| 607 frames in 5.0 seconds = 121.400 FPS
| 3664 frames in 5.0 seconds = 732.800 FPS       windowed
| 4407 frames in 5.0 seconds = 881.400 FPS
| 4372 frames in 5.0 seconds = 874.400 FPS
| 4396 frames in 5.0 seconds = 879.200 FPS

except that here the wheels turned very fast, the eye can not follow them.


It would be interesting to know if the problem exists on another distros 
using the same kernel.
