This is the problem, I got this logitech mouse (normal, not optical or wireless) and the sensitivity is just horrible, on the highest sensitivity mode it still needs to have the mouse move all the way from 1 side of the mousepad to the other to reach the other side of the screen.

So I tried screwing around with the settings a little but now its even worse. Whenever the desktop is displayed and everything else is minimized I need to move the mouse 3x to the other side of the mousepad to gt the mouse pointer from one side of the screen to the other...but once I open up a window or game, its faster again, but still fucking slow
