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.
