I recently bought, installed and calibrated TrackiR 5 and it seemed to calibrate correctly (although I know I have some tweaking to do). But there are a couple of things happening that I don't think have anything to do with the setup.
1. While flying in MSFS, I can get the target airport marker (the blue "bubble" with the distance above it) to disappear just by moving my head to the right place. And it's easily repeatable. When panning from side to side, I can see the label slowly fade to invisible, then reappear as I visually cross the spot where the label and marker are located.
2. When I start a flight, I hear a lot of random clicking sounds, as though switches are turning on and off in the cockpit. And the plane randomly starts and stops....even without my doing anything. I'm POSITIVE it's related to TrackIR somehow because MSFS works perfectly fine if I disable TrackIR.
I know there are others with issues and I'm not feeling very optimistic because most of the threads I've read don't have any answers, or are many years old.
So hopefully someone, somewhere can help.
