FPS uncap command

[jvasquez33]

What is the command to uncap your FPS in-game?

I'm getting terrible performance, crazy chop and stuck at exactly 64 fps and will not go above that. I remember it being buttery smooth with at least 90 fps and never moving from that. Even if I had vertical sync on it would be a 144 fps max, so I don't know dude. What gives?
