I have been using TrackIR for years now, so this 77 year old just doesn't seem to have many problems with it. Yes, the adjustments require you to be outside the program in which you are using it. Any bright light behind you can cause erratic behavior. Getting back into the program while running is done by clicking on the little up arrow in the group of taskbar icons over at the clock area, opening the TrackIR icon with a right click and choosing the top line (not at that computer now) by left click which allows you to open with your taskbar icon (provided you put one there). I much prefer it over VR for screen clarity, visual access to controllers, and reading and taking notes, charts, etc. In X-Plane, it plays with X-Camera nicely, but it isn't needed in MSFS. Yes, I tried VR as a friend of mine took me to a VR shop in a local mall back before Covid days. They had X-Plane set up and spent a lot of time getting everything set up "properly". and allowing me to fly unlimited by time. They stayed with me and tweaked it many times - trying to make a sale. It was not a clear image and, although I could see the 3D effects, it just wouldn't work. After bringing my friend home and letting him use TrackIR, that's what he ended up buying and has thanked me for "saving him" many times. Set a couple of easily accessable keys/buttons for "center" and "freeze" and you're good to go.
