Every time I think I fixed it it comes back a week later. I have never experienced such a frustrating issue in regards to flight simming.
Tried and for me instans stutters when “disabling” the rolling cache. But thanks for the suggestion and tip. Good it helps you and hopefully others.
Makes only a small difference and is more like a “hack.” I’ve switched it back on and now follow this concept:
Performance Boost for Strong Hardware – G-Sync OFF + Multi-Frame Generation (MSFS 2025)
Note: You’ll need strong hardware — ideally an RTX 5000 series GPU.
Well, I rolled back to Windows 10 22h2 from the Windows 11 24h2 that I was on. Not a single stutter, both on MSFS 2020 and 2024. Also rolled back to Nvidia Driver 537.58.
Performance looking pretty good. I’ve tested hard yesterday and today.
Weekends were the weak point before, always when the server load was bad, the stutters came. Not a single one until now. Looks promising.
I rolled back to 566.36 and after several different sessions the audio static associated with latency spikes went away. After that, I decided to try the latest driver again, but this time I used the studio driver instead of game driver. Flew two different times and again no audio static. If anything changes, I’ll give an update.
This. Thank you! For months I have been having this issue and THAT is what fixed it for me. I tried everything before that. Disabling EXPO, disabling PBO, even re-installed windows. It never came to my mind that the darn audio devices are the problem.

Please update on this
Glad to hear my solution helped you 
I’ve been having this issue with a brand new build (5090 and a 9800x3d)
Will try the studio driver to see if any difference
Just coming back to confirm that this solved the problem for good.
No more stutters and overal +10fps in performance. The sim is behaving way better on windows 10.
I updated my bios and seemed like things got fixed, but I started running into the same problem again. I was getting major CPU spikes associated with latency spikes. I started doing some searches and found through Ai overview that some people with x3d chips had bottlenecking issues. I decided to disable SMT in bios, but my bios didn’t have SMT. Found out if you enable Turbo Game Mode in Ai Tweaker bios, it shuts down SMT. It’s been almost three days with the smoothest flights I’ve ever had in 2024. No more latency spikes and no static in my headphones. One thing you’ll notice especially if you use this method is that your CPU usage will be high, but temps remain the same.
This! Exactly this. I also had enough of the awful overall performance on Win 11 24H2 and got to the point where I just nuked everything and reinstalled Windows 10.
And just like for you, its solved my issues as well. Am also seeing better performance with Win 10 than I got in Win 11.
Thanks for putting the idea in my head. It’s been a pain to back up all my data and basically start from scratch but its been well worth it.
Glad to help!
I bought another NVMe just for windows, that made the transfer way easier. Even that way I lost some good 12+ hours of transfering everything and making new configs.
It was WEEL WORTH IT. I can’t even describe how much the sim is smoother right now. Better graphics, more FPS. It looks like things just work on windows 10.
For anyone wondering if you should do It, don’t even think, just go for It. It’s WAY BETTER.
I think the problem was related to windows 11 24h2 new energy saving settings, putting our CPU on eco mode sometimes. It’s been a discussion on many of my IT groups about this new policy making things a mess. And It looks like Its happenin’ across many CPU intensive aplications, not only MSFS.
Hope Microsoft get things right soon, but until then, I’m laughing on Windows 10.
Until recently, I was using Windows 10. I also had Windows 11 23H2 and had blocked the update to 24H2 and I didn’t experience any audio stuttering back then.
I’ve now been running Windows 11 24H2 for some time and still no audio stuttering at all - so personally, I wouldn’t blame Windows itself. If anything, it’s more likely caused by user-applied system and/or BIOS settings or even an outdated BIOS, which can also affect performance and stability.
Additionally, factors like scenery loading in MSFS 2024 and the quality of the connection between the client and game servers can have a significant impact on audio stuttering and overall stability.
I hope you’re not mixing up the Efficiency Mode (ECO mode) for apps with some kind of CPU eco mode that’s usually found on laptops - those are totally different things.
In my case, Ryzen 7 9800X3D performs as expected under load, with no signs of eco mode or throttling - and that has remained consistent regardless of the Windows version.
Could you please share the links where these discussions are taking place? I’d like to look into the hardware configurations and system settings other users are reporting - especially those related to Windows 11 24H2 energy‑saving policies.
P.S. As for Windows 11 - in general, version 23H2 is definitely better for gaming than 24H2. I’m on 24H2 now just to give it another shot… let’s see how long it lasts. I already had one forced reset to default settings …

Hi! Sure, here are some examples:
On both of this forums you can see many users, on many topics talking about this stutters.
In CS2, it’s becoming more prominent, so you could start with that as well.
No, actually Windows 11 on 22h2 implemented some new ways of dealing with E-cores and how Windows itself interacts with the CPU. This update was further optimized in 23H2 and 24H2. It’s really good for people with newer CPUs, but users with older Intel CPUs, like me, have reported a significant drop in performance.
Also EcoQoS sometimes not really giving the best results in some applications, as seen on forums above.
Intel’s Thread Director generally works well on platforms like Windows 11 but can mismanage core migration under heavy multitasking or mixed foreground/background workloads. The stutters are likely tied to scheduling inefficiencies and context-switching overhead.
Additionally, older or hybrid CPUs (such as Alder Lake) face real limitations with AVX2/AVX-512. AVX-512 support was disabled on many chips from early 2022 onward, and both AVX2 and AVX-512 can trigger turbo frequency downclocking due to power and thermal constraints.
Thanks for the links. But just to point out - those threads are actually quite old, from around 7 months ago. Back then, it’s true that Windows 11 24H2 was not in a good state for gaming - I even mentioned that myself here on MSFS forum.
I was more interested in links or sources specifically about CPU Eco Mode bug - you mentioned something about it earlier.
When I was still running an i9 13900K - I also noticed that MSFS performed better when I disabled the E-cores directly in the BIOS. So yeah, I’ve definitely seen first-hand how Windows’ handling of E-cores can impact performance, especially in more demanding or poorly optimized games.
As I mentioned earlier - in my case, the Ryzen 7 9800X3D performs exactly as expected under load.
Also, I didn’t see anyone in those threads actually post a screenshot showing “ECO icon” next to a game process - which would confirm that Efficiency Mode is really being applied in that case.
Here’s an example of what I mean:
I also haven’t seen anyone mention anything about a bugged ECO mode at the CPU level either. Most of the discussion seems to focus on general stuttering or performance issues.
If you’d like to continue the discussion, feel free to quote my last post from this thread and reply in the topic linked below - it’s more focused on Windows and especially the 24H2 build, so it might be more useful for others as well.
It’s a better fit for this topic and might help keep things organized for others following the discussion.

Hi all,
I have this annoying pop and crackle of sound with a small stutter when playing the game.
It happens in all aircraft, and usually when panning around the aircraft.
I have a
5600x
RTX 5070
32gb ram 3200
It’s getting really frustrating to fly because it’s Happening all the time.
Thanks
Will
Are you Win 11 24H2? Seems like many that are having these audio stutters along with a CPU spikes are on that version of Windows
