I wanted to play the campaigns vanilla (SupCom, not FA yet) before I tried multiplayer or anything to get used to the game, and even on the first mission stutter gets extremely bad. It's not a constant low framerate or anything, so I'm not sure what to do. I googled around a bit but there's nothing too concrete on this issue, especially with modern hardware. Any help is appreciated.
update: I think it's because I'm moving my mouse. It causes an extreme lag spike for a minute, and it does it on Dawn of War as well. Tried disabling steam overlay, does not work.
