Summarize your bug Not only do I have terrible mouse lag, I also have keyboard lag, meaning, it takes between 0.5 and 1 second to my character to react to my keyboard presses. Also on fast flicks, I can see my mouse cursor, meaning the game does not pull exclusive focus for the mouse when playing with dual monitor setup.

Yeah is this a joke? The game has been out a year and this * is still not resolved.

Not only do I have terrible mouse lag, I also have keyboard lag, meaning, it takes between 0.5 and 1 second to my character to react to my keyboard presses. Also on fast flicks, I can see my mouse cursor, meaning the game does not pull exclusive focus for the mouse when playing with dual monitor setup.

I tried literally everything. Mouse polling rate, settings reset, disabling every overlay I could think of (good job btw EA that you can't disable the origin overlay when runnning the game through steam, complete amateur hour once again). I'd refund the game, but I've been tinkering with this for more than two hours so I can't. 

Oh yeah and my CPU is at 100% non stop when playing. I really can't believe this is real.

THis is my user.cfg with an 9700k
