Forgive me if I missed it already being mentioned in the 29 pages of this thread, but that workaround for the INTENTIONAL camera movement speed is only a small part of the issue. I personally could be very flexible when it comes to how much I have to move the mouse to rotate the camera a CONSISTENT amount. The problem is that, regardless of what the rotation speed is set to (or how it's set), it seems to randomly spin at an extremely large multiple of that rate. Perhaps some sort of bugged attempt at "smoothing." It's good to have read that a patch somewhere temporarily fixed it (must have missed that one myself), but it was most definitely a problem every time I've played (including yesterday).
