MSFS 2020 "Your Graphics card has encountered a problem". Update. Fix-ish
At the point of making this video last week I had not had any crashes since updating the nvngx_dlssg.dll file. Since then I have had one random crash (same error) but it's a vast improvement on what it was.
If you would like to give this a try then the updated .dll can be downloaded from here -

Update:07/03/2023:
Had one crash when I installed the new beta (because msfs reinstalled the old versions of the .dll's).
Since replacing them again with the newer versions I am currently having 4 to 6 hour sessions with no crashes.
