Once you've updated to 1.16.200 you'll notice an indescribable stiff sensitivity, which isn't affected by changing sensitivity, which I'm certain you'll get a lot of complaints about. Hard to improve a problem you can't observe. It's horrible to say the least. You now have lag when turning, that you didn't have on the previous and no it's not due to drivers or any settings. When you implement this great graphics engine onto other platforms make sure to allow them to demo it first.
