Description

Specifies a mouse speed that triggers accelerated cursor movement.

When accelerated, the cursor moves more than one pixel for each one pixel movement of the mouse.

The amount of acceleration depends on the value of MouseSpeed . If the value of MouseSpeed is 1 or 2, cursor speed is doubled when the mouse speed reaches MouseThreshold1. If the value of MouseSpeed is 2, cursor speed is quadrupled when the mouse speed reaches MouseThreshold2 .
