didn't even konw logitech mouse had this.
idk men ive been playing fine without it. raw input best input
just minimise as many factors as possible
mouse smoothing sort of takes the raw input from your mouse and makes a accurate prediction of where you want your cursor to be, which is great for older mice, but for newer (gaming) mice you want the input to be as raw as possible.
for gaming you want your mouse to register your movements as raw as possible, any (software or hardware) attempt to alter what is being shown on screen can negatively affect your performance and it’s the same with smoothing.
