I’m using head and eye tracking, but I tweaked the default settings. Here are the values I set:
0.93 Eye vs Head tracking ratio
0.80 Eye tracking responsiveness
2.00 Head tracking sensitivity: pitch/yaw
0.14 Center stabilization
1.00 Head tracking sensitivity: Roll
1.00 Head tracking sensitivity: Position
0 Head tracking auto-center
If you don’t want eye tracking you can disable it by setting the Eye vs Head tracking ratio to 1.00.
Additionally, ensure that in General Options → Accessibility “Cockpit Interaction System” is set to “LOCK” otherwise it will be harder to interact with the knobs by using the mouse.
