public void setRotationSensitivity(float rotationSensitivity) {
        this.rotationSensitivity = rotationSensitivity;
    }
Sets the rotation sensitivity. The lower the value, the slower the camera will rotate around the target when dragging with the mouse.
default is 5, values over 5 should have no effect.
If you want a significant slow down try values below 1.
Only has an effect if smoothMotion is set to true

@param rotationSensitivity the desired value (default=5)
