My system crashed twice then I went to Microsoft updates and updated windows and the crashes stop. There’s a new windows update out there that hasn’t been implemented version 21H2
Temps make no difference. Any clues in eventviewer? … and if not then 100% it is spike protection but it doesn’t necessarily mean there’s a fault

Those were the only errors that happened at the time of the PC shutting down.
Machine Check Exception certainly sounds like a protection process but I still think it’s this driver
Are you running Ryzen Master in Win 11? If so, try uninstalling that and update the latest X570 chipset drivers.
I did update to the latest x570, but am also running Ryzen master… so Ryzen master defaults to a prior chipset revision?
Tried 497.09 to check CTDs… ( Win 10 / 1080Ti 12Gb / DX11 ) crashed loading first flight. Rolled back immediately to 496.76, setup the exact same flight - no CTD.
Incidentally, 496.76 fixed all the lighting glitches that had been present since SU5 for me.

exactly the same here !
same here, my fan is litterally making my pc taking off the floor !! can’t even hear the game in headset with volume on Max. This update from Nvidia is GARBAGE.
I had such an improvement after SU5, when Asobo promised a perfect balance between CPU and GPU, then came SU6 along, and since then my fan is on 100% almost all the time through a flight. not allowed to fly when family is watching tv, because they can’t even here themselves think.
My wild guess is that it has been optimised for xboxers, and pc users have been left aside since SU6. so disappointed…so much
Did not upgrade based on CTD thread below this one, going to wait and see. Current driver works fine.
how do you go back to previous driver ?
The motherboard is not applying voltage to the CPU in the amount required at that particular moment in order to perform the L3 cache swaps fast enough and feed the GPU as dictated by the MSFS engine+GPU driver.
[EDIT]
What a mess… 
I have excessive cooling so I actually like the FPS increase I’m seeing.

This is what the new driver did to me. Blue squares on the terrain.
I also CTD 100% of the time when loading/spawning, or shortly after take off. Safe Mode ON.
Have you tried a DDU reinstall for that yet ? I had those issue when I installed the patch fix for the last driver update. I had to go back to a clean install to get rid of it.
With Windows 10 and DX11, I had one CTD immediately after updating to 497.09. I restarted FS, and then flew for a little over 5 hours with no problems. Frame rates appeared to be unchanged (55-60).
Yeah xboxers…that’s why your PC ■■■■■ itself hot when you run this …“xboxed” sim… Just. Come on…
