There is a problem with the mouse, I just wrote up a thread in the technical support area this morning asking if there is a work around to getting the mouse to work the way it does in almost every other game ever released or at the very least to act like it does in windows. No reponse so far, and I don't honestly expect one.

The mouse moves like it's moving through jelly instead of air, when you stop the mouse movement, the mouse continues on briefly. It is a very annoying aspect of the game and one that makes me just want to pull my hair out at times.

It doesn't appear to be a problem of tieing it to the frame rate since my frame rate is between 30 and 60 which in every other game that I play with the same performance of frame rate the mouse cursor works properly. It's borked in Divininty II in my opinion.
