Right now unless they fixed it on PC the mouse acceleration is out of this world. And yes I have all my mouse tweaks done, mark7 and all. I bought the game when it came out on steam and got my money back real quick. I really wanted to play it being that is was going to be my first in the call of duty series. Maybe later when they actually take the time to make it PC friendly, like maybe when they get dedicated servers. Thanks for adding the Mouse Sensitivity for this though guys, right on the money as usual.
