Audio Stutters In Menu / Globe And On Ground / During Flight

So I had this and as others have mentioned, it kept getting worse (from a start of random stutters in heavy scenery and no audio stutters).

Deleting the rolling cache and setting the size again to 120GB (since it resets), has had an immediate positive effect reducing not only the amount of stutters but also almost completely eliminating audio stutters.

I have further:

  • Disabled SVM (i’m on an AMD 9800X3D) from my bios
  • Disabled IOMMU
  • Disabled Nvidia Audio HD Driver (tried uninstalling but Windows keeps putting it back, so just disabled it from Device Manager) - this on its own did not fix the stutters caused by the rolling cache. This was the first thing I did and everything else listed here was still needed.

SVM and IOMMU are virtualization options in bios (to run virtual machines, etc. ) so if you’re not doing that, ok to disable. Found some older threads that recommended these to improve stuttering.

  • And I have reduced texture resolution to Medium, since I only have 12GB VRAM.

With all of these, I am now getting almost no stutters and definitely no audio stutters (so far). Tested with A350 inibuilds (very heavy on performance) and a320 FBW (light but still airliner) flying between 2 3rd party airports (EDDH and ESSA).

Definitely Asobo needs to get working on fixing the rolling cache filling up issue + optimizations. It’s not logical that the sim would wait for any scenery to load in, it clearly has super low resolution scenery to put in place when the internet connection is lost, so it should just use that until it can load in appropriate scenery at a rate at which it doesn’t impact the rest of the sim’s performance.

But doing the above has helped me so far. Still waiting and testing.

Has this still not been fixed? :smiley: I’m flying the 2020 again. Uninstalled the 24. I’ll see how it looks in a year. Doesn’t make any sense at all right now.

WOOOOW… I can confirm , removing the NVIDIA HD Audio Driver fixes the Stutter also for me!!!

Crazy, because, there is no audio device connected with. Removed, Reboot, Stutters gone…

I had the same effect at the weekend, I only use a USB speaker via Optical In.

I simply uninstalled the Nvidia HD audio driver and now only use the Realtek USB driver

My monitor has no speakers at all, now the MSFS2024 runs really smoothly after the SU1. :star_struck:

I tried this many times, seems to work at the beginning, until it didn’t.

Im gonna try the BioS thing, I don’t use virtualisation, so .. whata heck, I loose nothing trying this.

I have been repeatedly mentioning for a long time, across various topics, that during the installation of the Nvidia driver, I do not select Nvidia HD Audio and Nvidia App/GeForce Experience, so they are not installed.

So, during Nvidia driver installation, I selected only the driver, PhysX and clean installation – I did not install Nvidia app and Nvidia HD Audio.

I don’t have any audio stuttering issues, and it’s good to read that the driver installation steps somehow help users.

I think you don’t have the problem because you use Windows 22H2. 24H2 seems to be the culprit, but yes not using Nvidia HD Audio Driver is always a good idea.

I have also tried removing the nvidia audio driver. Unfortunately the stuttering is still there after removing and rebooting. It might be a bit better since I swapped the dlss version to dlss 4. But the audio stuttering is still noticeable. As I mentioned beforehand i still think it’s related to Win 11 24H2.

I had the bad audio stutters once again about 20 minutes into a flight, I let it play out and eventually a message popped up saying it was a connection issue. Everything was fine on my end so it’s definitely an issue with their side of things. I was quick enough to grab a 30 second clip right when it happened.

Alright I’m back with the stutters as well. The rolling cache delete is the only one that helped reduce stutters, so that’s a problem for sure, once it fills up. I started having some bad stutters, I deleted the rolling cache, set 30GB this time, and stutters went down. But not gone!

I still have intermittent stutters that also cause audio stutters here and there.
I tried the same route, time and plane (EBBR, EGLC, AVro RJ85, third party airports) and taking off from EBBR causes 1-2 stutters at some point during climb + 5-10 stutters as I get close to London. Solid 60 fps (with frame gen) and VRAM never exceeds capacity at any point.

I’ll keep trying with other planes, etc., to try and find something else to be the cause, but at this point, I’m half convinced that if I reinstall windows with Windows 11 23H2, it will be fine. Too many people reported stutters right after installing 24H2, and it’s caused so many issues for so many games (and also screwed Intel’s CPU launch :smiley: ) .

For me what fixed the stutters was turning Fauna OFF or, if you want to live with Fauna ON, rollback to drivers 566.xx. Somebody say it’s only a placebo but for me it worked. HD audio uninstalled no effect, HAGS off no effect.

Are you on Windows 11 24H2 by any chance ?
I’ll try the fauna thing as well, doesn’t hurt to try at this point :slight_smile: Frustrating that this isn’t even being looked at by Asobo (feedback logged, not bug logged, so i assume they are not fixing this in SU2). I’m so close to just giving up on this sim at this point.

I totally feel this. It really ruins the fun. The sim runs ok otherwise and looks better than 200. But I get those random sound stutters in msfs 2024 only. Tried everything.

Another one here with audio stutters. Seems to have got significantly worse since updating to SU1 RC.
Always accompanied by a frame stutter. I also use BATC which seems to make it worse but probably just because it’s making the sim work harder. Very annoying.

Yes it seems dependent on how hard the sim is having to work. I’ve largely got rid of mine now after taking on board some of the suggestions on here.
However if I increase the sim rate they return and stay with me even after returning to normal sim rate.

Allright I found the fix for me for the audio stutters, just restart pc, and make sure no program is started that uses your sound system (making sound). Then, startup MSFS2024, spawn and load in your airport, and then you can start loading your applications like discord, browser, youtube ect.

I did wonder if BATC is a potential cause - as it’s technically an external application that is using sound. I did a flight yesterday without it and didn’t have any audio problems.
