the sensitivity is messed up on mine. before with my logitech optical wheel mouse (the ambidextrous red mouse), i was able to move my cursor to where i wanted it to with ease. now, i usually either fall short of where i want to click or i go too far with my cursor. i tried adjusting the settings already but it still doesn't feel right. trying to play quake or counterstrike is terrible. does anyone have this problem and what is your sensitivity settings in windows?
