What the hell are you on about? Whats this Mickey... Mickey Mouse?! EH?! Registration?! I don't play CS, so I have no idea on this... High Knowledge Response Users only?... Sounds like a group! To me, this is so **** confusing, the reason why I responded? Because of this: There is a significant amount of RSI that comes from using a standard mouse (the vertical mouse doesn't have much at all!), and the reason why acceleration exists that high, is because of that, I have my acceleration set to the highest possible, because of the 3 monitor setup I have. I hate picking up the mouse and moving it back and forth to get it from one screen to the other. So that pretty much sums it up. Either I have said something useful, or I am dribbling information out of somewhere. But to me it makes sense.
