Hello, I have this problem with MW3 in both single and mutiplayer. So I have noticed that on my 4830 this game ran like a pig back when the game was first released, so I never gained interest in it. However I was using a 6670 the last few weeks, and we decided with some friend to play MW3 multiplayer. The game ran perfectly on the new videocard and I had no problem with it, however I had to say goodbye to the 6670 and use my 4830 instead. And the problem on the video card is this: normally the game runs at 50-60 fps however there are frame drops very frequently and stutter. The frames drop to 1-10 and the stutter is awful. The game freezes and I can't understand why. I tried with old and new drivers. Nothing seems to help. And I know the GPU can handle this game because I play a lot more demanding games than COD, and in terms of raw power the card is the same as the 6670. Any suggestions?

Raw power does not necessarily bridge the gap over two entire generations of cards, but what CPU do you have?
