Same here, MSI RX5700XT, but only in the Reverb G2 VR. In 1080p flat screen no problems, Previously in the Rift I didn't have problems either while GPU load was also maxed. Except a restore of Windows I tried about everything, so I'm now going to do that.

Glad I didn't restore Windows. The AMD 20.9.1 WHQL driver seems a well working, stable version. My above problem seems to be gone. I immediately noticed a difference when switching between headset and desktop, the framerate would much faster settle.

More here, I didn't do the under-voltage or other tricks, just the driver 20.9.1:

Keep in mind i have also found certain liveries ... free ware Addons, ... payware addons conflicting with each other....

In my case, it can happen with an empty Community Folder.

But after alot of messing about i rolled back my drivers to version 20.8.03 and carried out the advice from HERE And i was down to maybe one or two every few days.

I tried this and it did NOT help, gave me CTD on first try. I would not recommend this as a majority of CPU/GPU vendors recommend using their latest RECOMMENDED drivers.

I am using latest recommended AMD driver with better success.

Of course they do, otherwise why release updates? But that doesn't mean that the latest drivers for any product are necessarily the best for every user in every situation. Unless an update provides a patch for a security issue, there can be many good reasons not to update drivers, or indeed any program. If it ain't broke...

I just completed a total flight time of over 5 hours (including both active and 'passive' pause) without any issue. Well, I did experience a crash, but that was me failing to flair properly on landing - still getting used to the Thrustmaster Airbus controls in the A320! Maybe that was just co-incidence that I didn't CTD, but that was my first flight after rolling back to 20.8.03, following the two CTDs I had earlier in the day. I might have more CTDs waiting to happen. only time will tell...

Exactly the issues i was experiancing until i rolled back to that earlier driver set up, and the tweak they suggested to the performance settings. Just about every flight ended in ctd.as  I tried each new version as they came out, and the only difference i got was experiancing ctd's  2-3 times a day.

The game changer so far is i have now run the latest driver released a couple of days ago, and have not had one ctd since. still flying 3-4 hrs daily.

Unfortunately, it was the Adrenalin 2020 Edition 21.1.1 Optional which I'd just installed and was continuing to result in CTDs, so I will stick with 20.8.03 for now and see how that goes. Another overnight flight just completed without failure👍🤞 If I can steer clear of CTDs, I'll probably wait until such time as AMD release another driver with an MSFS-specific tweak.

Ah, good you have got it stable now, yeah i don't blame you for leaving it as it is, i was the same for weeks.

Since I too was having CTDs with the latest driver, I would urge caution. Be prepared to roll back.

20.9.1 is working for me, not the latest but it works. May be different for others depending on configruations.

A successful 16 1/2 hour flight from Antarctica to Rio de Janiero with 20.8.03 and the aforementioned tewaks. Definitely sticking with this while it works.👍

Good news, glad its working. I had the one ctd last night on the latest driver, but at least it was'nt the normal driver timed out error. Tonights was a Vcc Runtime error, removed them, and re installed so far so good.

Is this a 5700xt Specific thing ? Im on the latest driver and i haven't got any ctd's. Granted my max is three hour flights at a time but since Friday when i switched cards apart from dialing in the Overclock for the card and getting rid of the occasional stutter there has been no issues (6800xt).

Probably not, I'm also running 6800 XT. Before January I had smooth sailing, 80 hours of CTD-free flight. I didn't touch a single setting, but now for the last 4 weeks CTDs have become quite frequent (the VCCRUNTIME140.DLL combined with AMD driver crash and recovery). Roughly one CTD every flight or for every 2 hours of flying. Both with newest drivers and the recommended one 20.11.2, which I rolled back to this week. 

I have tried most of the recommended fixes but so far none have fixed it for good. The only thing in common with the CTDs that I can think of, is that I was flying over terrain I hadn't flown over before.
