I'm not sure if I'm 100% right on this but I think that the controller settings affect your mouse settings. Aim acceleration is turned to 10 by default in the controller settings. I was wonder if you guys could turn all controller settings to 0 and test to see if I'm correct with this. It wouldn't change the fact that you still need to crank up the dpi if you're a low sens player but it could help with matching sens.
