Ok, thanks for the update! The invert X checkbox works. But, now the up-down is inverted!
Also, it would be great if the Sensitivity range could be adjusted, slider to the left is still too sensitive for me.
More testing: seems like the up-down positioning isn’t right. It’s connected to the pitch axis!
If I move the HMD up the Y-axis doesn’t change. But when I tilt the HMD forward the Y-axis goes up!
