Sorry I have not tended to this post in a week

I have tried different USB ports like suggested but same result. Looking for the firmware update on Google brought up stuff about better tracking ability on surfaces, not the lag out part. Its a shame because its only a year old, but then again it is the first gaming mouse I had so maybe it is common. Will put a little more time into research. Not sure if I want to spend money on a new one just yet, but it is really annoying when you are about to finish off your victim with a pistol in BC2, and you just end up running a circle around him waiting for your mouse to come back alive....
