So yea, I have a problem with mouselag that can't seem to go away. I have literally replaced every single part in my system, and no matter what, it still persists. Changed the mouse, motherboard, video card, processor, monitor, every conceivable thing. I always have about a half second lag between when I actually move my mouse, and when the cursor moves. What gives? I can't seem to find any online sources to fix this either. It essentially makes playing FPS games impossible. Anyone help?
