Which axes do I need?
After many frustrations with jittery views I merely turned off the axes I wasn't needing.
All I need is:
YAW - looking left and right
PITCH - looking up and cown
X - moving my viewpoint, or virtual body, from left to right.
The result?
Buttery smooth panning from left to right and up into the turns.
Sometimes less is more!
