I think that some of the video problems are caused by the Physx engine, my game had some choppiness, so I tried increasing the video detail to max and clicked all the buttons, helped but my XP machine with a 8800GS and a 19" widescreen LCD still played the game perfectly and my Win7 with a GTX260 and 22" widescreen LCD was still a tiny bit choppy, so I tried installing the newest version of Physx, as soon as I did this and restarted my game the machine was crashing every 5 min and artifacting something terrible, so I undid the changes and will put up with a little stutter, mind you it is little, but I thought I'd pass this along
