For some reason, when I rub up against the wall, a.k.a wall rubbing , I get stuck sometimes and I have to sacrifice the glory of cover, to get unstuck.

Another problem I am having was that when im in-game, im lag free on a Nvidia 6100 nForce 405, but when im in the menu on a 800x600 resolution (when my monitor is like 1440x900) I lag, the interface does not lag, but the mouse is kinda large because I put the resolution so low, and well the mouse lags, it does not do that in such games like Battlefield 2 and other stuff, is this a problem with my graphics card or what?
