Sorry to raise this thread from the dead.
Recently re-installed this since getting my new PC, brute force power finally runs this game as it should
Single player is smooth as butter, however multiplayer is another story .....
The frame rate seems to jump around like crazy, seemingly 15-30 FPS depending no how it feels. I get the feeling its down to my co-op players system having an affect on things, such as if it runs like shit for them, it tries to match it on my system to keep everything in time.
Does anyone know if this is the case ? Or is it just borked ?
