They broke TrackIR in the update. They knew they broke it during the Beta and pushed it out broken anyways. If TrackIR loses sight of a LED (like you look away for a second, take a drink of your coffee, sneeze, etc.) then it turns off. If you pause trackIR, then it moves view back to center and turns off. You can use the Camera tab in the toolbar to turn it back on each time or even assign a option to turn it back on, but that doesn’t stop it from turning off again and again. And it doesn’t fix the issue of you no longer being able to pause to look at/adjust an instrument.
There’s a bug thread at Track IR Stops Working PLEASE VOTE to have this fixed. The thought of flying without TrackIR is a real bummer and my flight simming has currently been put on hold. That includes any spending.
