Low FPS in OpenGL games

Ok… One of my friend have a GeForce 2 MX200… Other friend have a GeForce 3 TI… I have a GeForce 4 MX460… we are running, for example, Quake 3 Arena with the same configuration, but all 3 boards get 100 FPS!!! How??? And how we can “unlock” this “limitation”?


seta com_maxfps “300”

instead of 300 you can put the desired number of fps.
