As long as you can adjust the DPI of your mouse you can achieve the exact same result by doing that.
Technically it is a lot better too since raw input has less packet loss and you won't skip pixels like a madman.
I've added third-person now, you can select between first and third in the "View" special option.
Note that changing the distance by scrolling in or out does not change the FOV, so the sensitivity is the same regardless of distance.
of course is not same feeling , its smoother
just spend a week get use to it
