Everything is working fine now. I have a lot of pleasure flying in MSFS2024.
Here is what I did that probably solved my problems with drifting TrackIR:
- I installed the latest version of TrackIR (5.5.3.317). I thought that having the “check for software updates” checked would be enough, but it wasn’t. I had to manually check for a new version and install it.
- I put a 0.1 dead zone for all axes of my Rhino X56 HOTAS. It was probably once the mini-joysticks that caused the drift.
