It is pretty basic how it works. The mouse portion just replaces the right joystick, and that is about it. Other than that everything is just a remapping of the buttons. You will not be able to turn around any faster, because the game accepts a max x & y value and that is the same as holding the joystick all the way to the side. It will provide better control overall, but not necessarily faster speeds.
At least, that is how I understand it
