I'm not sure what's causing the crashes, but they happen in all kinds of different ways. Sometimes FSX just shuts down and disappears (no "error detected" window from Windows). More interesting is when everything goes black and eventually I'll see a red "overspeed" popup on the bottom because my plane is nosediving. After the plane crashes, the FSX window disappears.
All up to date with 1.62.
And while I'm here: the compass heading bug highlights, but doesn't respond to input.
ETA: Some more details:
Display in FSX and the Vive go black, but it's just the cockpit view. I can hit "esc" and open up the menu to end the flight. But when I get to the main FSX menu, I get a debug/shutdown notice from Windows.
(Also a ton of phantom buttons above the right dash, and the gyro drift knob doesn't respond)
