I just got a WMO and since I started using it - first I didn't install any drivers and my FPS crashed randomly all the time. So I turned of FPS counter and it isn't my FPS going down but it still jitters randomly all the time. So I installed drivers and rebooted ect but the jittering keeps happening. It's making LG / rail ect impossible. Only happened since WMO though.

Any ideas? :S
