Short answer

Updated Oct 8, 2026

'Enhance pointer precision' is Windows mouse acceleration: the faster you move the mouse, the further the pointer travels. MouseSpeed, MouseThreshold1 and MouseThreshold2 set to 0 turn it off, so the same hand movement always gives the same pointer movement. In the registry it sets MouseSpeed to 0 under HKCU\Control Panel\Mouse, and 2 more values.
