I have searched up and down for a solution for this so I was wondering if anyone here had any ideas. Started playing cop after I got my new video card and while it plays with fairly good fps it hangs when playing for a bit then will come back. More frustrating though is how long it hangs when going to the main menu or saving. Haven't seen any fixes for this problem but it seems to be something specific to windows 7. Everything is up to date. Catalyst 11.3, steam updates the game so that is patched. I have tried turning off anti virus and shutting off non essential processes. Its not a game breaker. But frustrating considering the plays smoothly otherwise.
