Re: Game lags when I move my mouse

This happened to me last night too.

High end pc. 

No hardware or setting changes that I made (any invisible updates??)

48 hours ago it was fine, 24 hours later I log in and it is unplayable. 

There is no FPS drop unless I am moving my mouse. I can strafe, move, shoot, etc. Insane, unplayable FPS drop when moving mouse. Even in menus, if I move my mouse, FPS drops and game stutters. 

All other games are fine.
