Quick update. I wrote a little too fast in my earlier post and mixed up some terms. It was turning off head tracking (not eye tracking) that helped keep the view centered.
So I gave it another try again tonight and I can definitively tell that it something happenning with the headtracking part.
I’ve resetted everything in the Game Hub, put Eye Tracking sensitivity to 0 and had the same problem. It feel like by default, Tobii make my character head look up by about 20 degrees higher than normal centered view. Disabling head tracking and having only Eye tracking worked as expected: I was able to look around as it should and my in-game view was centered (when my head and eyes were).
The only thing that helped me having an in-game centered view (with my own head and eyes in normal position) was to increase the Start point parameter (I mixed up the term with inflection point in my previous post). It act of course like a dead zone, but it doesn’t feel natural.
Can this be a problem with the Game Hub itself? I see no option in Elite Dangerous menu about Tobii…
