Mmmmh i mean it could be. Maybe it has something to do with a windows update. I’m on the latest Windows 11 version, Nvidia driver 591.74.
Apart from that, I haven’t actively changed anything else on my system.
Unfortunately, I have no idea what might have helped or whether this is just a lucky streak.
I’ve had this kind of problem in the past. Windows Update would regularly overwrite one of my drivers without any warning… 
You can disable automatic driver downloads from Windows Update by changing a registry setting. Open regedit and go to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DriverSearching
then set the value of SearchOrderConfig to 0
This will prevent Windows from automatically downloading drivers.
Restart PC.

Soo… ive never had an issue with the audio stutters after SU4 anymore.. until today. I experienced some performance issues, so i completely reinstalled NVIDIA Drivers , BIOS update(disabled/deleted the High definiton nvidia audio and that) and it happened again. Now the dreading stuttering is back.
- Rolling cache is disabled 0.0
- No Audio drivers except realtek
BUT… i have found something that causes this as well. Ofc, this happens in the air, but what i noticed, it now happens if you change the date of the weather! Look at this!

I get the same thing its like when something is loading from the hard drive I get stutters and audio cracking. Hope someone figures this out.
I fixed all my audio and stuttering problems by matching my display output to what my CPU/GPU is capable of handling. I was demanding TAA @ 120hz in 4K on a 55” TV, which normally my hardware can do it. (It does it fine in BF6 etc) But the way MSFS works between the rolling cache and separate page file the sim creates every time you load in, the only solution for me was to run it in 60HZ mode in 4K. Then tweak the in sim settings to match the on screen latency of 16.67ms. Once this was complete, the only other thing I did was I went into the aircraft.cfg files of each of my 3rd party aircraft and disabled pushback tug and any other active services BUT leave jetway active otherwise your jetways become static. Asobo still hasn’t fully fixed the loading of default assets on the ground when on short final. Now no more problems, sim runs smooth as silk native 4K @60hz, I only use FG to give the smoothness feeling of 120hz. No DLSS
For reference I have a 9950X3D and a RTX 4090 with 64GB CL30 6000mhz ram.

I did more troubleshooting and figured out the rolling cache (also) seems to cause this. I’ve always had it disabled. Now turning it on for the first time again.. horrible stuttering.
Has anyone tried SU5 beta yet with windows update 24h2/25h2? or do we still need to stay on 23h2 for no audio stutters? thats been my case so far, never one stutter in 23h2 and always audio stutters in the newer versions.
I tried it a few times earlier today, on 25H2, and the only audio stutter I heard is the one I usually get during the sim loading process. Nothing after spawn in though.
Ok, and you had audio stutters on SU4 with 25h2?
Yes, but again only as the sim is loading. I never get them when flying. It’s the same effect you see with lots of games as they load, where they have a progress bar or spinner of some kind, and it’s animation stutters as it loads assets into memory, sometime accompanied by an audio glitch as well.

I’ve heard a lot of opinions about ReBar and I still don’t understand what it does lol, and I’m a technical person
REBAR is a fonctionnality that theoretically allows the CPU to access VRAM more efficiently.
Rebar ON:
- Advantage = a few more FPS (approximately 5 FPS)
- Disadvantage = consumes VRAM, and therefore less VRAM is available for MSFS.
Rebar OFF:
- Advantage = more VRAM available for MSFS
- Disadvantage = slight FPS loss (approximately 5 FPS).

I see, so this would most likely help systems that are CPU bottlenecked, right? Don’t think it’s my case, so I’ll disable it and report back
Well, disabling rebar seems to have done wonders for my vram. Thanks for the suggestion.
After many months of not one audio pop and stutter, this morning it came back with SU4. Wonder if their servers are getting hammered again. There has been no change to my system or settings within those many months.
I wonder if these stutters are related to public beta testing? The last time I had this stutters was during SU4 beta and they disappeared after SU4 release, now they seem to be back soon after SU5 beta has started. Even if we don’t participate in beta, the servers must be running two separate sessions to provide different data to beta and non-beta users.
Amd9950x3d,4090. After monts of audio stutters - it suddenly went away for the last 2 months. Thought maybe a new windows Update. And now this evening the audio stutters are back. Strange. Not in su5 beta.
