I ordered today a new 500GB Samsung 970 EVO Plus in order to replace my old 110GB 850 EVO SSD System drive. Hopefully, this also will improve my perfomance when I upgrade to W11… even if W11 still won’t show up in my updates. 
But I’ll trust Microsoft on this one and will not use online Installer untill I get update offered.
You can kick off the download manually by running the Win11 Installation Assistant:

Yes, I know and I may do that in a few days. Just going to wait a little longer to see if anything bad shakes out.
I’ve been running it in Beta mode for a couple of months and I love it. Nice interface, smooth as butter, auto HDR is working great. Basically zero issues or complaints.

I intended on ‘waiting’ as I realize ‘somethings’ gotta becoming soon… we’re at the top NOW… with i9s
I am on the dev channel of Windows 11.
So I get the flaky updates that may not be stable.
Since the update!
Flight sim 100 percent stable
Overclocked system.
Core temp has dropped by two degrees.
Gpu memory temp has dropped by four degrees.
Not a single crash or hang.
Windows 11 is looking buff for MSFS 2020

I’ll second that. Feels real solid…
Installed Windows 11 last night. For a new OS things went better than I expected. I had to update a few pieces of software, but otherwise has shown not any issues.
MSFS started off very cranky, but has now tamed down to at least Windows 10 levels. I checked the resources used between two similar flights (Prestwick to Glassgow). There was very little difference between the two runs. Some resources were lighter in the Windows 11 run V’s the Windows 10 run. This could be purely down to a clean OS install over an install that was at least 6 month old. There was a 5 fps gain taxiing around Glassgow airport, again could just be down to a clean OS.
As far as MSFS goes I saw no detriment from upgrading whatsoever. I did see some issues with some apps though. Spacedesk for ipad needed the latest version. HWinfo works better on the later version 7.12.
Remember any tweaks you may have added for Windows10 most likely need to be reapplied as in (for me) High performance preferred in power profile, nVidia drivers and texture filtering. Turning off “game mode”, “hardware accelerated GPU scheduling” and disabling full screen optimizations on the exe file.
In my case it was HAGS, that I had to turn off again. Had the same experience. All good now.
Best wishes!
It’s been smooth sailing or should I say smooth flying with me just upgraded to Win 11 last night…
I thought HAGS was supposed to be on. Am I wrong?
Installed last night. I have an ASUS mother board and during the install an ASUS ap opened and updated all the drivers. I did have to reinstall my HP printer. I have an eight core processor and while running the sim, I noticed that all sixteen cores were running . So far, very smooth and no regrets.
Power profile one of the first things I sort. Windows used to be a pain for removing minimum CPU power. I sift the system processes also to remove anything I don’t want. But I have to admit I had some stuff installed on Windows 10 that is not on Windows 11. This is why I added the proviso of clean installation.
With Windows 10 I just installed Virpil tools for new stick, along with Thrustmaster for a Hotas. No need for those anymore as all is set up and saved to the hardware. (Virpil constellation alpha sticks are gorgeous)
I have seen realised I lost a macro I spent an hour writing up for diablo 2R. Pretty annoyed with myself for not backing that one up.
I heard that “High Performance” is nothing but the waste of electricity in gaming, as your CPU can already adjust itself and its frequency. This option should only be used for servers.

Just turn VBS off No big deal
Not necessarily as it also keeps e.g. drives and usb from sleeping and maybe your cpu from throttling down unexpectantly. Mine actually uses an AMD high performance plan and my benchmarks are always better with it on.

Well, first of all I want to give a big THANK YOU to all those on this forum who are so willing to help those of us (especially an old 82-year-old like me) when things don’t go as planned. As mentioned above, I suffered severe frame rate loss after upgrading to Win 11. By turning all the graphics options either to off or low, the best I could get was 21 fps and jerky at that! Reading the posts here, I began to experiment with other settings and nothing worked. This afternoon I saw a post about HAGS – sure enough when I looked, Win 11 had turned HAGS on. Turned it off, and just finished a flight with my VR graphics settings all back to Ultra and High (actually, some are higher than I had with Win 10 before) and my frames never fell below 32!!! The sim has never been so smooth and enjoyable. Hope this helps others who may have similar problems. Now back to flying!! – an old guy from Maui.

Wow one would think with the new Windows 11 MS might have got HAGS right this time. It certainly was best to leave it off in Windows 10, guess the same will continue to hold true in Windows 11. Just checked mine and it is off by default ( upgraded yesterday). But I already had in off previously in Windows 10.
I am with this problem too.
