I remember posting a thread like this yesterday about this issue but man it's becoming dissapointing and I really wanna play this game that **** bad. However whenever I enable V.Sync the game seems to stutter alot and iI'm wondering if anybody had this issue and found a work around it? OoSuperMarioO

I had this problem, very annoying. Got rid of it by enabling the Dual Video Cards in the options menu in COD4.

I don't have Dual Video Cards and you may not either but it seems to get rid of the problem.

I have Vsync on and can't stand it off so i can see why it racks you off.
