Since 1.5.x.0 (currently on 1.5.2.0) I have been unable to fly using VR in the West coast USA area, this has been happening for the last few nights (GMT+1, UK summer time).
I live in the UK and my current server is Western Europe, my Internet connection is 1Gbit/s - typically running at between 800 - 900 Mbit/s.
My PC has a AMD Ryzen 9 7900X, nVidia 5080, 64GB RAM.
VR is Pico 4 Ultra connected via Virtual Desktop.
I am able to fly in and out of London Heathrow and London City airports (both normally quite demanding locations) with no issues with a frame rate at or about 45 FPS (limited at 45 FPS) typically using about 9 - 12 GB of VRAM.
When I select an airport to fly from in the West coast USA area I am still getting 45 FPS and using a similar amount of VRAM but during or shortly after take off the simulation judders to a halt, followed shortly after by the programme shutting down and returning to desktop, VR still working quite happily via Virtual Desktop.
I can reload the flight simulator and if I select a European Airport all works fine but if I again select an airport in the USA (e.g. John Wayne airport, KSNA, LA Intl KLAX, and others) it still crashes back to the desktop at or shortly after take off.
I have tried a number of nVidia drivers from 572.83 through to the current 576.52 and all fail in the same way.
Any suggestions?
I will try other areas of the world like East Coast USA, South America, Africa, etc. to see how they work.
Edit, I have tried a number of GA aircraft and the same happens with each of them.
Edit 2.
Restarted Sim, and tried the following airports:
Logan - OK no issues
Lisbon, Portugal - OK no issues
Beijing - OK no issues
Honolulu - OK no issues
John Wayne - OK no issues
The last one surprised me so I shut down the Sim and tried John Wayne again, this time it crashed to desktop during take-off.
So not sure what is happening.
