Logitech SetPoint Utility
About
SetPoint is the name of Logitech's unified driver suite for its mouse and keyboard products. It is the successor to the company's MouseWare and iTouch driver suite.
For mice, it has three sections: Mouse Button Settings, which allows the user to change the function of each button and have different settings for different programs; Mouse Movement where movement settings and sensitivity can be changed; and Mouse Game Settings, in which the gamers can change settings for in-game, set up to 5 different resolution presets, and have separate settings for different games. If a Logitech keyboard is also used, 2 extra sections are added, in which key functions can be changed.
