Gamers engaging in popular FPS games such as Counterstrike generally play with the mice configuration set at the lowest sensitivity level for more precise and accurate targeting. However this results in having to move the mouse over a large surface area repeatedly when moving in-game, like for example making a 180° turn. With current 2nd generation sensors, this swiping action causes the cursor on screen to move unintentionally away from the targeted area.
