Mouse gain / cursor speed
This feature determines how far and how quickly the pointer travels on the screen compared to how far the mouse is moved.
Discussion by Disabilities
Adjustable pointer settings allow people with physical disabilities to tailor pointer behavior to their needs, which may vary greatly from one individual to another. This feature may be most helpful for those with limited mobility who cannot make large mouse movements or to filter out erratic movements caused by hand tremors.
