Gosh, I had the same thing. But that was with a 5080. Check all your graphics settings are not conflicting. Also, use ddu and go back a few drivers. 577 i think folks were recommending. There are a few threads here about these Driver issues

Or send a private message to TenPatrol. He is very helpful.

Hello and thanks for your answer,

how can I have ‘conflicting graphics settings’? Who conflicting with what exactly?

Chris

Okay, it wasn’t the driver. I did ddu and installed 577.00. I’ll write TenPatrol next.

But then I’ll re-install the game. But via Steam. It’s on sale here in GER (47.99€, Premium Deluxe). I hope I won’t have to deal with these stupid MS apps ever again because that’s where the trouble lies. I mean, the MS agent literally re-installed WIN 11 remotely. How can that not fix everything?

Cheers, Chris

There are obviously 4 different sets of graphics settings. Nvidia, screen, windows and the sim itself. If not all working together it causes issues. Secondly, there are reports of the nvidia app itself causing problems particularly in 2020. And then Dx 11 is incompatible with later nvidia cards. Really, get a hold of TenPatrol. He knows pc’s

FYI, I helped the OP with his issue. As far as I know, Microsoft support also tried to assist, but they couldn’t solve it.
The important thing is that MSFS is now working for him :slight_smile:

Thanks so much for the kind words! But if you tell everyone to send me private messages, I won’t have any time left for virtual flying - just kidding :rofl:
Microsoft support staff tried to get creative, but sometimes overthinking things backfires :smiley: Still, they also deserve thanks for their good intentions.

OK, no more messages :sweat_smile: :+1:

So, other than TenPatrol saved the day, what was the actual fix for this, in summary?

This would be useful for others to know if they ever encounter a similar issue and find this thread through a search.

We eventually reset WIN 11 and I updated it until the latest 25H2 version, marked as a preview version. It wasn’t an easy fix but it seems to have worked. MSFS is running again but I am still picking up the pieces (installing scenery, all the 3rd party apps etc…).
Reset WIN 11: Settings –> Recovery –> Reset this PC –> Keep my files
Before the reset, all apps to be removed will be shown via link. I, for one, saved all my e-mails before reset, for instance.

One of the Windows updates got bugged - it was an update that couldn’t be uninstalled, so the only solution was to restore Windows to a state before the update was installed and then update it again.
