MSFS 2020 CTD after todays 8/7 update

udidwht · August 7, 2025, 9:06pm

Just had (2) consecutive CTD while the sim was loading. This was after I had already updated to SU 16 the other day and had several successful flights. Upon start of sim it wanted to update again (Nav aid update?) . Once it updated it began loading then approximately 50-60 percent into loading it crashed. It did this (2) in a row. Running 580.88 drivers (clean install and no NVIDIA app). Did not have this issue prior to today’s update.

The following are the event logs…

Going to do another clean install of GPU drivers with DDU and will report back. Will use 580.88 (no NVIDIA app)

udidwht · August 7, 2025, 9:59pm

Success!

Uninstalled NVIDIA driver software using Revo Uninstaller. Then rebooted.
Disabled network card then rebooted into safe mode.
Ran DDU then rebooted.
Installed 580.88 drivers (no NVIDIA app)
MSFS 2020 started sucessfully

NVIDIA get your (you know what together) you’ve been dropping the ball lately with ■■■■ drivers.

BearsAreCool510 · August 7, 2025, 10:09pm

Nice. And this is with DX11?

udidwht · August 7, 2025, 10:13pm

Likely when switching from one to the other and back.

BearsAreCool510 · August 7, 2025, 10:43pm

Sorry, not sure what you mean. I just wanted to confirm that your fix solved the issue for DX11.

Ashippun5411 · August 8, 2025, 12:12am

To have to do all of that is ridiculous to be able to run any program. Far cry, Red Dead, battlefield, Call od duty, never ever had to do any of that craziness to be able to run after an update.

Asobo needs to hire better programmers.

udidwht · August 8, 2025, 12:29am

Looking as if it’s an NVIDIA issue.

Well after doing what I did in the 4th post I just had the sim CTD again while starting up loading. I had made no changes to the sim settings after the previous clean install.

These are the event logs…

Installed the NVIDIA app and hit ‘Optimize’ and the sim started.

But for how long?

Going to leave the sim settings as they are and report back if I have any other CTDs.

Similar problem here. Crashed with a Space Plane error then wouldn’t start at all. Got this error. Never seen it before.

@udidwht
I spent a bit of time today testing 580.88 with MSFS 2020 and DirectX 11 without the NVIDIA app.

So … if you don’t want to play MSFS 2020 with DX12 - for example, because of a performance drop - you can go back to driver version 577.00.
You won’t get CTDs during loading in MSFS 2020 if you choose DX11, as long as the NVIDIA app is not installed.

In the topic linked below, I explained how to do this properly and shared some additional details on how to correctly roll back the driver.

After some months of flawless flights, in the last two days I have experienced some CTD’s which start as freezing and the CTD. No idea what could be causing this, since no new drivers and no new elements in Community have been added. That’s quite frustrating…after 5 years of MSFS!

udidwht · August 22, 2025, 1:42am

What’s showing in the event viewer log?

Also rnn the following commands (w/admin rights) and when all completed successfully and without error/s. In the following order:

Dism.exe /online /Cleanup-Image /checkhealth

Dism.exe /online /Cleanup-Image /scanhealth

Dism.exe /online /Cleanup-Image /Restorehealth

sfc /scannow

Dism.exe /Online /Cleanup-Image /AnalyzeComponentStore

Dism.exe /Online /Cleanup-Image /StartComponentCleanup

RESTART computer as the last step.

I’ll run what suggested by you and try. I’ll report back in a couple of flights.
