OpenGl/GLUT and Matrox

Hello Everyone!

I’m developing a game at the university and although it’s still pretty basic (2 spheres on a plane, no textures, no lighting) it runs terribly slow.
The systems are Athlons from 300 to 1400 MHz and Matrox Millenniums 400-550 afaik.
Are those cards THAT bad? It should work without any problems, shouldn’t it?
Could a driver update fix that?
