Interesting. Indeed when running with compiz enabled (without
INTEL_BATCH FWIW). I get the following results:


[colin at jimmy ~]$ INTEL_BATCH=1 glxgears
libGL warning: 3D driver claims to not support visual 0x64
8107 frames in 5.0 seconds = 1621.257 FPS
8368 frames in 5.0 seconds = 1673.456 FPS
[colin at jimmy ~]$ glxgears
libGL warning: 3D driver claims to not support visual 0x64
6213 frames in 5.0 seconds = 1242.563 FPS
6344 frames in 5.0 seconds = 1268.641 FPS

That's a good FPS improvement!

That said it has been stated time and time again that glxgears is a
crappy benchmark. Still it's still nice to get more FPS regardless :D

Cheers
