I'm running i7 6700 1080ti 16GB RAM on 4k Getting 40-60FPS but the mouse lags so hard it takes sometimes a WHOLE second before it moves on the screen. The whole game feels choppy like it was running below 20 FPS (I'm running the inbuilt counter and Fraps to make sure it doesn't) . Seriously this makes this game unplayable. Another thing is you can't change the resolution from the native to lower cause the game resets itself. WHAT IS THIS GARBAGE PERFORMANCE AND OPTIMIZATION????
