MSFS2020 simulator freezes or CTD in Windows 11

Hello. I had a problem with CTD and freezes after switching to Windows 11 when minimizing the window and switching to another open program, for example a browser or any other program. By method of exceptions, I found that this happens when you activate the vertical sync mode “FAST”. Does anyone else have such problems? And maybe there are some solutions? I used to use G-Sync, but after the 3rd patch, the opportunity to use this feature is just broken… I would be grateful if someone can what what to help.

I’ve had that problem since I upgraded to win11…
And thanks for finding the culprit!
The “FAST” sync mode in the Nvidia settings seems to be the problem indeed!

Yes last two flights CTD with windows 11
Although it might be down to LEAL I downloaded from flight

But I am an insider had never had CTD since upgrading to Windows 11 and have gsync enabled and vsync on fast in NCP
What should I set vsync to or just have it set to off?

Same problem here when using another program/screen that overlaps with MSFS (especially when in the menu) you almost always CTD when switching between the program and MSFS.
I also use vertical sync mode set to “FAST” for MSFS in the NVIDA control panel.

Interesting. I started noticing this and I think it’s because I recently switched to fast v-sync. I’m trying now with it just set to ‘on’ - hoping it’ll make a difference

Hello. Doesn’t anyone have this problem? Or no one uses vertical sync in “FAST” mode?
