I just got this mouse and I have to say I'm surprised how high the lift-off distance is for a gaming mouse. This really hinders FPS-gaming when you lift up the mouse to re-calibrate your crosshair position and the movement goes crazy.
Changing the lift-off distance is something you desperately need to add to your software, other mice like the Naos 5000 and Razer Imperator allow you to lower it via the drivers. Hopefully this is something you guys can fix in a firmware update.
