I recently rebuilt an old PC to use as a secondary PC just for gaming. I installed Win 7 and the MarkC mouse fix, but I still don't find it comfortable when aiming at long range targets. (I also disabled mouse setting in games, for example in Arma2 I've set X axis, Y axis and smoothing to 0.)
Any other suggestions besides the MarkC fix I could try?
The mouse I'm using on that PC is a Genius NetScroll 200, monitor resolution normally is 1440x900, but when I have some time to swap video cards with my main PC I may use 1920x1080.
