When i disconnect my PC entirely from the internet (both cable and wifi), the sim seems to be running without stutters. So it seems to be indeed network related.
When i disable the Online Functionality within the sim, it does not help and the stutters are back. So it seems to me another service is the problem. How can i find out which one?
windows 10 or 11 installed?
Start easy. Close background apps one by one to see if one of them is the culprit.
As I said above, use resource monitor in Windows to see which process is using network at the time your stutters happen. This can get a little tricky though, so I would just get a free version of Glasswire. It has a graph of network usage. You can click on a spot in the graph corresponding to when your stutters happen and it will show which processes were using the network and where they communicating to. There are other tools that can do the same thing as well or better, but that is the one I used to find out dasHost.exe was creating stutters.
A more powerful tool is sysmon (Sysmon - Sysinternals | Microsoft Learn), but it is admittedly more difficult to set up and use.
I too have a stuttering problem not just in MSFS but other games like DCS and itâs driving me crazy, and I see the same constant refreshing in device manager that you mentioned. I have not come across a previous reference to Microsoft edge possibly causing a problem though. You said the solution at the bottom of your post but seems maybe you forgot to post it? Could you clarify?
@WartedSummer2 , thanks for this! I used Glasswire and found indeed that dashost.exe was connecting every minute to the internet. After disabling this service, the stutter was gone. Super!
As dashost (or DeviceAssociationService) is a default Windows service for pairing wired and wireless devices, this sounds to me like a problem at Microsoft. But why do only a few people have this problem?
Anyway, i am glad i found it and was able to solve it. Thank you all!!!
Iâm glad you found the culprit. I would imagine quite a few people have problems with it but just donât know it.
A word of warning: dasHost.exe is a windows process that is important for pairing your computer to other devices. Disabling it entirely may present other problems for you. If not, great. If so, please consider below.
I noticed my stutters were caused by dasHost.exe communicating with my Amazon Fire TV Stick. In a sense, it was the Fire TV Stick causing my problem, not dasHost.exe. Its communication with other devices did not cause stutters. I also read in forums (ED) that the same issue was caused by smart TVs.
What I did was create a firewall rule that blocked incoming and outgoing communication between dasHost.exe and the local IP address for the Fire TV Stick. That way dasHost.exe could function normally otherwise.
If you notice problems with functionality, particularly communication between your computer and other devices, itâs probably because you have disabled dasHost.exe. It will then be worth it to investigate your issue further. See which device the process is talking with that is causing the problem. Make firewall rules to prevent communication with that device.
Hi GregP7617
If you click on the âblue text, framerate drops rapidlyâ in the earlier message it will take you to the full post.
But below is a copy of what you need to do to fix the problem.
If you have the ârefreshing problemâ in device manager, To Fix it, you disable the SSDP Discovery Service, and the problem goes away. Maybe not a solution more of a workaround until Microsoft waken up ( Thanks to CharlesHanson2 on the Answers. Microsoft website)
1, If you are on Windows 11 right click the âStart buttonâ and open Computer Management.
2, click on Services and Applications then Services ( a long list of services will open )
3, Look down the list for SSDP Discovery
4, Double-click on SSDP discovery, and then properties will open, where it says " Instartup type " just Disable and save".
The " Flickering Device Manager " stopped immediately for me.
I wonder if this service gets disabled when Windows game mode is enabled? One of its functions is to disable/suppress some services during gaming to better facilitate game play.
I thought i should add to this, in case anyone else is suffering and nothing else is workingâŠ
TL;DR: Check Windows Event Viewer for repeated âPlug and Playâ events, and fix that issue
After having the freeze-every-minute symptoms I ran sysinternals processmonitor and took a capture for a while and looked at things going on during the freeze. Looks like msfs is reading all the capabilities of usb devices. But, I heard no usb disconnect/connect sounds.
I took a look at Device Manager. if i just let it sit, after about a minute, it refreshes and the system device and network adapter trees fly open. if i collapse them, itâll do it again in a minute. So i look at windows event viewer. Its FULL of âplug and playâ events. Every minute!!! And looking at the details of the entries points to my networked PRINTER! 
I opened up printers & scanners and removed the printer. Now, device manager has stopped refreshing and nothing new is appearing in event manager! We did have a power outage a few days ago, and when that happens the printer gets a bit stupid, itâs âonâ but not really functional. I rebooted the printer and reinstalled it in the printers control panel. With the reinstall, device manager opened the same trees and there was new plug & play events in event viewer, but only once.
The freeze is gone!
I was also having a large stutter occurring every 62 seconds, thanks to this article i uninstalled my network HP printer and the HP software and it seems to be fixed!!
