Hopefully we will get closer to 1 to 1 mouse movement instead of the joystick emulation we have now! As it is, it tends to make me a bit sick, especially in the water. Love the gameplay, and I want to love the flying it's just the controls are keeping me from getting there.
Yes we have now enabled a way for you to get to 1:1 mouse input in flight and swimming as well as fixed a bug that was causing symptoms similar to negative deceleration in aiming.
