thank you. I added this to my XF86Config, and now glxgears reports:
880 frames in 5.0 seconds = 176.000 FPS
878 frames in 5.0 seconds = 175.600 FPS
883 frames in 5.0 seconds = 176.600 FPS
880 frames in 5.0 seconds = 176.000 FPS
878 frames in 5.0 seconds = 175.600 FPS
more than 50% better. However I ran into unexpected trouble building
gltron and have been too busy/distracted to make it work it yet.
If you know of a good open source opengl benchmark, I would be
grateful to know about it.
