Gears is not a benchmark.

"Gears is not a benchmark." Correct, but I haven't been able to get any benchmarks to successfully run yet. I would be happy to run any you suggest that work. I feel that the low FPS seen in glxgears is indicative of the low FPS seen in other OpenGL apps on my system. Such as OpenArena running at less than 60 FPS.
