My bf just installed a GeForce Mx 4000. We play a game called THERE. In the game, we play paintball. In order well to shoot he need to line up his crosshairs on a target. The problem is his mouse is going haywire. Its just too fast, he has turned down the speed, he disabled the acceleration on the mouse. It never used to do that with his other factory card.. I hope that someone can get back to me with some kind of resolution.. I am clueless on graphic cards etc..
