I might have a strange issue which i am having for a long time now.
Every minute or so, i get (mostly) 2 stutters. See the following video which shows my issue:
The stutters start in this video at around 11 seconds.
I tried:
changing settings within MSFS
changing windows settings (like HAGS, Game Mode, etc)
upgraded my entire PC with new hardware (memory, CPU, GPU, motherboard, HDD)
checked my internet connection (which is above 60Mb/s)
upgraded to Win11 (and back to win10)
there is no thermal throttling on my processor
no matter what i try, i always get these stutters. I read a lot of forum messages, but non seem to solve my issue.
Can anyone explain to me what causes this? How can i check what causes this?
Any help would be appriciated!
My current specs:
MAG Z590 motherboard
64GB memory (3600 MT/s)
GeForce RTX3070
i9 11900K @3,50 Ghz
EDIT
I noticed in the Task Manager, that during the stutters, the CPU, GPU and Network are dropping down. When the stutter is over for a few seconds or for a minute, the CPU, GPU and network get back to normal.
Try this: DX12, Hags off, Reflex Mode On+Boost. You might want to add Render Scaling 120% in the game settings so you are consistently GPU bound. Restore defaults in the NCP. See this Zendesk article. You need to restart the sim after setting DX12 and Reflex mode, and you need to reboot the PC after changing Hags.
As a test, try turning off just the real time weather as it should improve the CPU utilization on you’re system that is already mainthread limited. When I have real time weather on I have volumetric clouds turned down to high as it helps the cpu and I can’t really see too much difference visually.
I had a similar problem, but only with certain aircraft. I traced it to voice attack, however I recently updated voice attack and the stutter has gone.
Hope this helps someone.
When I built my new PC with an AMD CPU I came across this problem:
It looked exactly like what you experience here, stutters like yours precisely every minute or two. I am aware that you have an intel CPU but since it looks exactly the same you might check your BIOS version. It might be something else but with the stutters happening precisely every minute that’s not caused by the sim or hardware, that’s a software issue. In my case an update to a fixed BIOS version cured it. Any 3rd party addon can of course be the culprit as well, FSUIPC has already been mentioned, its autosave cuases that too.
Have you tried running the sim in offline mode (disconnect your internet) to see if it still stutters?
The network usage bit is interesting. I would investigate it more. Use the resource monitor in windows to see what process may be using network while the stutters are happening.
I had stutters (in MSFS, Elite Dangerous, and a couple other games that relied on internet connection to function) that took several weeks to diagnose. Ultimately, I discovered the stutters happened when dasHost.exe communicated with my SmartTV. Making a firewall rule to prevent communication between dasHost.exe and my SmartTV’s IP address solved the issue completely.
You can use Glasswire to more intuitively monitor network activity. If you see spikes that correspond with your stutters, you can click on that spot in the graph and see which apps were active and where they were communicating to.
I had a very similar issue (maybe the same) a while ago, on a nearly completely freshly installed and high end system. Got a HUGE stutter every minute on the dot. It appeared about 2 days after setting up the system after upgrading. Drove me nuts. I was unable to get rid of it trying all kinds of stuff including using a tool to monitor latencies etc. Ended up restoring a backup of the fully freshly installed system, ie directly post Windows install. Luckily it went away and never came back. So it was definitley a software issue of some kind.
I think it may have had something to do with an HP printer driver, really not sure though.
You’ve tried reinstalling Windows completely from scratch, right? And disconnecting all peripherals?
It’s hard to say what the problem could be as it seems to have persisted through a total rebuild and a fresh install of Windows!
I had a similar problem and if you look at my video below the stutter is at a shorter interval and was a Windows problem where the Device Manager app would refresh every 15secs or so and that alone caused the stutter.
@BearsAreCool510 , yes i did a complete rebuild (all hardware and fresh install of Win10). Just to make sure that there where no old drivers which might cause this issue. But the problem remains…
Hi DutchAirways
My problem wasn’t the USB devices ( see end of post ) it was the device manager applet, when you opened it you could actually see the device manager applet constantly refreshing, and when I opened it on my second monitor the refresh matched the Sim stutter. This problem was related to Windows 11 and Microsoft Edge Browser. ( This is a known problem with Windows 11 seemingly, it was easily sorted, info at the bottom of the post.)
In Task Manager, On the processes page, are any processes showing any sign of increase during the stutter? … Not the Performance page.
Does the Sim run OK without the Ethernet cable plugged in? ( I have never tried it ) as out of all the work you have carried out the only constant is your connection. Out of curiosity have you a usb WiFi dongle to connect your PC to the router by WiFi?
You are not using any Antivirus/ firewall but Windows?
