Not even lying, I've searched the Internet for like 25 minutes, found NO one else with my exact problem....so I bought MW3 last week and started playing Multiplayer...I have about 4 hours in game and all of them have been great until today...yesterday it was fine...today in game mouse sensitivity is so fucking fast it jumps from 1 side of the screen to the other with one little poke at the mouse...(exaggeration but it's pretty damn close...super sensitive) and my in game sensitivty is so lower, switching it farther down even to damn near 0 doesn't do a thing either. My windows mouse settings haven't changed one bit ever so this can't be it....anyone have help suggestions..I've tried everything to no avail. My PC mouse is just some basic generic USB Logitech mouse.
