I found a lesser used one. It hasn't killed my game FPS entirely, and it hasn't exactly been publicized. It's free, and you can record anything with it. Just set the size of the screen, or use full screen.

I have a link in my sig....
I would describe it as a wild PVP beat-em-up, with heroes/villains from different periods of time. Its definitely better than its lame counterpart rumble fighter.
From what these guys are saying...I might as well just record with something like Xfire than edit it with Vegas.
