The polling rate indicates – in layman’s terms – the speed of communication between mouse and driver. The higher the polling rate, the more often the driver “polls” the mouse. The more frequently this query is made, the faster mouse movements and keystrokes are processed. So if the speed is important, mice with higher polling rates are to be preferred. Mice with lower polling rates such as 125 “stutter”, i.e. transmissions, occasionally stop. It should be noted, however, that an extremely high polling rate can overload the driver – in this case, the mouse requests would be processed late. In practice, the polling rate is irrelevant in most cases. However, if you are looking for an extremely fast response, as your favorite games require enormous speed, you should choose a mouse with a high polling rate.
The mouse correction, also called Angle-Snapping or Mouse Prediction, is especially useful in graphics programs. This is a function to “falsify” the actual mouse movement. If the mouse detects that a straight line is being drawn, it will hide all other incoming signals and keep the cursor on the straight line. The drawn mouse line is smoothed artificially, so to speak. In the gaming sector, such a mouse correction is an enormous obstacle. If you try to move the mouse precisely, the mouse correction may intervene and prevent it. For this reason the mouse correction should be able to be deactivated at least in the mouse driver.
What better way to try and illustrate this than with Paint?
The Lift-Off-Distance indicates the distance that the mouse sensor must be at to the ground to stop scanning. This value is especially interesting for players who lift the mouse and reposition it. With an unlimited lift-off distance value, this new placement would lead to unwanted and uncontrolled cursor movements. For gaming mice, the value should normally be between 1.5 and 1.8 millimeters.
