Like many others, after updating to the MSFS to the 40th Anniversary Edition I am experiencing stutters, momentary freezes and CTDs. I've unsuccessfully tried a variety of solutions.

Yesterday I happened to see this item:

https://learn.microsoft.com/en-us/windows/release-health/status-windows-11-22h2#lower-than-expected-performance-in-some-games

On October 18, Microsoft released Windows 11 22H2 (build 22621). Microsoft published the issue statement on November 10, the day before MSFS 40th Anniversary was released.

I have submitted this to Zendesk.

@FederFlyer,

Thank you for the important note!

- Luckily enough my Win11 is running MFS Su 11 + 40 th smooth & silk.

Yesterday I even decided to push the very last Nvida driver and installed it. Then I deleted the Win Shaders cash, and after starting MFS all was fine.

This sim is so bad for me 😞  I wanted to find some good reason to uninstall it for good, but I can't... 😞

A couple of weeks ago, 22H2 was installed on my PC. I immediately noticed a loss of performance in MSFS. Everything else worked fine. Fortunately, I was able to roll back to Win 11 21H2, which works great. I recently read that MS halted deployment of 22H2 due to gaming performance issues. I believe that the article said that MS had enabled (and left enabled) some debugging modules in 22H2 which caused the issue.

How did you roll back to the previous version of Windows?

 

In the 1st 10 days after install, there is a roll back option shown on the Windows updates page. Press the Windows key, type "updates" and press enter.

Edit: I just noticed that 22H2 is now available again for me. It has been showing a "Not recommended for your machine" label next to the update since a couple of days after I rolled back. However, the article I mention above states that it still has problems and was written today.

Microsoft confirmed that a GPU bug in Windows 11 version 22H2 is lowering gaming performance on some systems. As a result, the company placed a compatibility hold on affected devices, preventing them from receiving or installing the update.

"Some games and apps might experience lower than expected performance or stuttering on Windows 11, version 22H2. Affected games and apps are inadvertently enabling GPU performance debugging features not meant to be used by consumers," said Microsoft.

I'm still on Windows 10, and haven't read about an equivalent update for my OS that is causing issues, but the stutters since the update are terrible (and inconsistent — most of the time they're present, but sometimes they inexplicably disappear).

Last night I noticed that if I switched to offline mode (after seeing so many of the network errors that others have been seeing) all of the stutters disappeared immediately until I reconnected to the network again later on. No idea if anyone else has experienced this?

That sounds a bit weird.
It must have something to do with the cache or similar.
Is your C drive full? Someone told me it needs 150 GB free space to operate MSFS properly, regardless of where it's installed.
Or if your MSFS drive is full, maybe it's trying to cache the scenery when connected.

Update: I received a response from the Zendesk team that they looked at the link that I provided regarding the Windows update issue, and have forwarded it to the development team.

Probably why I had to download the 22H2 optional update 3X in 3 days for WIN 10.

I posted this before, follow this simple tutorial and you will have 60 days to rill back to the previous version instead of 10. I always use Macrium Reflect to do a full image of my Windows drive as well before any major update.

Can you expound on this, what is this win shaders cache?

If like me the 10 days have expired to enable a roll back you might like to try this suggestion from a reddit post that advised people to disable an Nvidia service called "NVIDIA FrameView SDK service".

The person reported that I clicked "Stop" on that service and ran the game again. All the stuttering issues disappeared; the game worked well now.

 

Here is the reddit post, I have NOT tested it with MSFS myself:

 

My server has the latest W11 updates incl this one and I have not experienced any framerate drop…

It still baffles me how Microsoft can hype, beta test and the hype some more a 40th anniversary product and yet not test it thoroughly on their latest update, using the most common recent ndivia drivers. 

Just baffling.

I did a recent install of Windows and now they pretty much force you to sign in with a live account,when you install Windows 11, so they can spam you with stuff from the app store.

For those who don't want to give Microsoft your data
