I'm using an Xbox 360 controller.
The right analog stick is too sensitive. The slightest touch will make the camera turn.
Also, after using it, the camera will still spin unless you try to center the analog stick precisely in the middle to make the camera stop turning.

In the System Configuration menu, there is an "Analog Stick Sensitivity" slider. The slider seems to only adjust for the Left Analog stick used for moving your character.
There needs to be one for the Right Analog stick (camera movement).

Would really appreciate a Dev response or acknowledgement.
