The answer is included in the glxinfo output:
[3]------ glxgears
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
Right. You want it to look more like this:
[mlapier@mushroom ~]$ glxgears
20670 frames in 5.0 seconds = 4133.959 FPS
20746 frames in 5.0 seconds = 4149.087 FPS
20731 frames in 5.0 seconds = 4146.106 FPS
20744 frames in 5.0 seconds = 4148.615 FPS
20741 frames in 5.0 seconds = 4148.097 FPS
20570 frames in 5.0 seconds = 4113.860 FPS
20724 frames in 5.0 seconds = 4144.629 FPS
glxgears IS NOT a becnhmark and was never one!
I never said it is a bench mark, or that it ever was one. What I said
was that his display is locked to the refresh rate of his video screen
and that he should look there for the solution.
He didn't state what glxgears was reading before as compared to what it
is reading now. I would only use glxgears to indicate a *relative*
change in performance from one configuration to another. The actual
result is essentially meaningless except for a comparison between two
configurations on the same hardware. Without the result from a previous
run, under similar conditions, there is nothing to relate to.
Example:
I went from using the Open Source nouveau driver at about 200 FPS to the
proprietary Nvidea driver at 4100 FPS. A *relative* improvement. The
proprietary driver also gave me 3D acceleration that was not working at
all under the OS driver.
