It's a Logitech G500 USB mouse. All the cheap meese's are sized for female hands and my fingertips were dragging on the mouse pad. This is a full size moose with adjustable weights and 4 different speeds. I have it fully weighted for smoothness and the speed set to the max of 2400 dpi. I have looked into the controls section of the vanilla and modded COAS and have not found any difference. POTC and every other game works fine.
