The game is really cool, but I can't get my refresh rate to go above 60hz which is annoying becuase the screen keeps tearing and I don't want to put vsync on. Does anyone know how I can change the refresh rate is this game? My refresh rate stays the same in all my other games so I don't know what the problem is.
Doom 3 limits your FPS in the regular game. I believe to 60 fps like you stated. Try running a time demo, in that the limit is disabled. I'd try looking around and seeing if there is a way to edit the config file to allow higher fps in regular mode.
