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

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.

I’ve been running without BATC in all my testing, so that’s not a cause for my stuff.

I’m trying to find the motivation to downgrade to 23H2 to test that hypothesis :slight_smile: But since Asobo isn’t even acknowledging that this is something they’re looking into…

I will not downgrade to 23h2 and I don’t see the point in making my system less secure just because Asobo can’t do it. This post currently has 319 messages and 4900 views. What else should we users do to make Asobo realize that the fault lies with them, or with Microsoft? I can still see the point of updating a driver. But I can’t ask them to carry out a bios update. Even if Asobo hasn’t said this, some people here are doing it (including me) The error should finally be rectified! The simulator has been out for four months now. In my opinion, this is a disgrace what is being delivered. I would love to play the 24. But the problems with the sound are just annoying and ruin the flying experience.

Let’s take a more scientific approach. My thousands of flight hours and extensive experimentation have led me to formulate the General Theory of Stutterevity, expressed as the following formula:

S = c * (1 + l)²

Where:

  • S – stuttering intensity
  • c – aggregate flight complexity, ranked by impact: photogrammetry + DEM detail + LOD + aircraft complexity + other sim settings
  • l – aggregate streaming latency: content-demand-induced latency (how many people are streaming the same content as you) + game server latency (determined by your location, ISP, etc.)

This theory explains why some people don’t experience the problem and why Asobo is unable to reproduce it. In both cases, aggregate streaming latency (l) isn’t high enough to trigger the issue.

Flight complexity (c) alone can theoretically induce stuttering even without streaming (when l = 0, so (1 + l) = 1), which is why I encountered the exact same audio stuttering already in FSX when using highly detailed mesh (DEM). While MSFS is more efficient at handling computational load, the stream-it-all philosophy of MSFS 2024 shifts the break-even point for stuttering, making it more dependent on latency than sheer complexity. This also explains why MSFS 2020, which relies less on streaming (e.g., mesh isn’t streamed), is less prone to the issue.

Due to the variability of aggregate latency (l), the same flight complexity (c) can sometimes induce stuttering and other times not. This leads many users to believe they’ve found a solution, when in reality, they’re falling for a post-hoc fallacy.

Downgrading Windows, changing drivers, tweaking settings, or throwing snake oil at your PC has zero impact on the root cause.

Great post and formule. You are right, I tried All Snake Oil. The problem must be on the server-side…
Due to some new hardware I have been testing the same scenario over and over the past week. Today during the weekend I noticed much more stuttering. Must be server load as nothing changed on my side…

I don’t think this is necessarily server-side. Could be exacerbated, yes, but not the sole reason.

I’ve done the exact same route multiple times, trying different settings, etc. .
There was no difference between when I loading the scenery for the first time, versus the last time when the download meter was almost zero the entire time.

It’s definitely scenery-loading related, though. And I don’t have a problem with a slight graphical stutter here and there, the problem is this stutters the sound at the same time and just becomes an annoying thing after a while.

Anyway, I stopped playing the flight sim for now altogether, I found myself troubleshooting issues more than flying, need a break :slight_smile:
