Myself and probably every other person playing this game has horrible mouse controls and sensitivity.

Either you have to deal with V-sync and having a delayed response to your keys and mouse movement, but have even sensitivity

Or have V-sync off but having the Y-axis being 3 to 4 times more sensitive than the X-axis because the Y-axis is tied to the frames per second you are getting.

I have no found a solution to this and not sure if anyone else has either, but PLEASE FIX this horrible issue.

made a topic about this aswell, seems the only thing we need is a option to support "hardware mouse", until then its

best to can your FPS using a program UNTIL they fix it, IF they fix it
