I have topped out the control panel, and it is still too slow. I like a really hyper mouse for gaming. Once you get used to it, it really speeds up your shots.
This is in OSX, so maybe one of you UNIX command line types will know a hidden command?
BTW I changed my mouse LED out for a blue one, very pretty and no change in function. I have tried a couple of mice, but really would like the Apple mouse to move faster, I put four hours into changing that LED. If you do it, go to Radio shack and get a really bright LED, the ones from most electronics shops are not strong enough.
