I have a 8600 GTS which has been OC'd substantially (it was built to be OC'd, so it is not an overheating issue) and an AMD 64 X2 2.4 Ghz processor. I can run CoH on high settings with out any problems with a drop in frame rate or lag. Red Orchestra, a much less graphically intensive game on the otherhand, has a very low frame rate. Before I upgraded, the game was fine, but now, it is like I am watching a slide show of myself playing the game. Obviously, this makes it rather hard to function. I was asking in game, and some guy said it had something to do with the dual core AMD, but I couldnt find any information about that online, so I though I would as in here.
