Mouse Look Speed
 

Is there any way to fix this? It was fine, but now whenever I log in it takes like 6 swipes across my mousepad to do a full circle. I haven't changed any settings, sensitivity is set at 100% in game, my mouse speed outside of right-click-look is fine as well.

Any ideas? It's so annoyign I don't even want to log in.

Set your frames per second to 50 or lower.

There is a slider bar in display options. Set to 50 or lower and problem is solved.
