Game dragging

[Fobxmunk]

I am getting a weird kind of lag when i play this game. my video card is geforce 6800gt and runs fine on other mmo's, but when i try to run around or use mouselook and run, when i stop running on my keyboard im still running in the game for a few seconds longer. it doesnt get choppy like lag, its just dragging really bad..... anyone got a clue? ive messed with all the video options and what not, still no resolution.
