Any time I'm in a vehicle - aircraft, land, sea - using internal view, the game freezes and crashes. Starts with audio stuttering and frame rate dropping. Sometimes will bounce back, but usually leads to freeze/crash. Sometimes it's so severe I have to restart my computer. It never happens with external views.
Update: After weeks of frustration, I found out it's my Logitec G933 headset that is causing this issue. I ran it earlier with speakers through on board sound, and there appeared to be zero issue beyond the fact that I can't use any VOIP or in-game voice.
