I have deadband turned off or maybe just slight above off. Try turning it off and see what happens. Deadband, per my understanding, is intended to eliminate pot/signal spikes due to worn or older pots on your joystick. Why that has anything to do with nose bounce is beyond me, but it does.
Just to clarify, nose bounce is when you release/recenter your stick and the aircraft nose oscillates in the pitch axis. Even with nose bounce reduced, stick inputs must be done smoothly to eliminate oscillation. Increasing dampening 'forces' smooth inputs but removes the option for quick movements.
