This is with either using the mouse directly, or using the mini-stick on my throttle (which I have remapped to mouse) - both incidences, the mouse view, which was once very fluid and snappy in PE is now slow and even, dare I say, jerky somewhat with BH&H II (this with identical settings).
Just pointing this out.
(Edit: Panning with a Hat still works well as before (snappy and fluid)).
