So when playing any FPS, when I slowly move my mouse it feels like the screen moves pixel by pixel. Quite jittery. However when the actual game moves the camera slowly, everything is smooth as baby's butt.

Screen is at 144hz 1900 x 1080
AMD 7970HD GHZ edition
Ram 8 x 2
Win 8
Inter i7 3770k

Please help.

Thanks.
