For some odd reason lately (The past few months) whenever I play a PC game my mouse moves much slower if I'm pressing buttons on the keyboard. So like in an FPS game if I am standing still and move the mouse to look around it's fine, but if I start walking forward or back or side to side or pressing any other buttons (like crouch, sprint, etc) my look speed is MUCH slower. The first time this ever happened, on Chronicles of Riddick, I figured maybe it was just part of the game (Like if you were moving you couldn't turn as fast) but it does it in all my games. It does it outside of games too but I rarely have to use my keyboard and mouse at the same time so it doesn't bother me. I'm 99% sure this is a software problem and not a hardware problem, as it works fine when I use my mouse and keyboard to play UT3 on my PS3. Any suggestions? If it helps my keyboard is Logitech and my mouse is Saitek (I know it's not the best mouse but it was a gift)
