I've tried several things to get my refresh rate above 60Hz in Tribes 2 and other games. ReForce was no good, setting stuff in the ATi control panel was no good, DirectX forcing it with dxdiag was no good either. And I can't seem to edit my registry since the only instructions I've heard of are for win9x not 2000 (i can't find the file in the registry they talk about). I set my monitor down to 1024x768 and it still runs at 60Hz in some games.
I sure don't know what to do. I have to use vsync to prevent tearing too, which limits me to 60FPS max in the games affected by the problem.
