These numbers all sound weird to me. I get 300 fps on an ancient Matrox G200
on a system with a 700Mhz Athlon. At work we typically get around 1600 fps
in glxgears with Radeon 8500's on systems with 865 chipsets and 2.4 - 2.8 ghz
P4s. Sub-100 fps for glxgears seems slow even for software rendering.
