Well here’s hoping more of us are not affected. I am happy Asobo is looking into it if it is affecting many users. Each time you talk about the audio stutters you also include just the word stuttering as well. Are these then complete system stutters where all systems in the machine are being affected at the same time or do you have times when only the audio stutters? I have experienced system stutters in past testing (which are hugely diminished these days) but never just audio dropouts by themselves. BTW, I typed this prior to your post edit.
How are you getting your final sound, from a speaker system or headphones? There are external pre-amps with wonderful equalizer features that could do what you are asking without any additional taxing of the computer.
Edit: I should add that I have friends that are audiophile purists that play an album from CD and then from a vinyl record and swear they can hear vast differences. Me no.
Headphones these days my neighbours complained about droning engine sounds through the walls when I used speakers. 
I prefer CD to Vinyl for the sound quality, the dynamic range of Vinyl is limited to about 60dB and they take a lot of looking after to avoid clicks n pops.

When I mention “stuttering”, I’m referring to frame stuttering — basically, the game freezing or hitching momentarily, not the entire system. Audio stuttering or dropouts are mentioned separately when they occur. So when I say “stuttering” alone, it’s the in-game frame hitches, not a full system freeze.
In MSFS 2024, we’re dealing with all kinds of stuttering - both frame stuttering and audio stuttering. Frame stuttering also affects audio: when the game freezes for a 0.5 or second, the audio stutters at the same time. This is the main issue in MSFS 2024 and only when it’s properly fixed will I consider uninstalling MSFS 2020.

The SU4 Beta performance is outstanding, and this comes from someone who has never experienced significant performance issues with MSFS2024—just an occasional stutter, but overall, it’s been great. What really stands out to me are the UI improvements; it used to feel clunky, but now it’s seamless. I’ve also noticed that the stutters have completely disappeared with SU4 Beta. However, I’ve reverted back to SU3 for now so I can enjoy flying some of my other airliners like the PMDG 777 and Just Flight’s Avro RJ. I will return once the Beta allows me to fly the airliners I previously listed.

I agree on the smoothness - if it weren’t for the stuttering, I’d call SU4 the best beta I’ve ever tested for both MSFS 2020 and 2024. Unfortunately, the stuttering really spoils the overall experience.

I see a few stutters on the ground, usually when turning during taxi. But its inconsistent, so I mostly blame it to environmental circumstances like weather, lighting, AI traffic that are different on every flight, basically changing every minute.
But so far I had them so little, that I do not really consider it an issue. Never had audio stutter so far.
So I consider myself lucky to coincidentally found a suitable mix of settings to suit my system and I will not touch any setting ever again unless a new build destroys my current happiness with performance.
All I need for overall happiness now is working jetways, navdata update on the A350 and working A380. But performance is not an issue here.
Extreme flickering with DLSS even from main screen makes it unplayable. Had to switch to FSR3 to go away but….
For what it’s worth was a 120hz TV running nicely previously…
I would be happy with audio stutters atm. Voices in SU4 beta are really soft, especially ATC - real hard to hear let alone understanding what ATC has to say. Didn’t have it in SU3 or before. Also reverted back to SU3 and all audio is ok. Any advice?
Especially because it seems only a few encounter this issue. See link below
As you probably know, I was hit by stuttering and audio stuttering. It occurred in SU3 and the SU4 beta.
Initially, I thought it was caused by the SU4 beta because the audio stuttering and stuttering appeared right after installing it. But I left the beta, and I also had stuttering in SU3.
I haven’t had any stuttering for the past two days, and I’m testing at different times of the day since, luckily, I can afford to do that. If the stuttering comes back, I will let you know. I changed my system version from Windows 11 24H2 to 23H2 and one system setting, specifically HAGS. HAGS probably doesn’t affect stuttering, but it does have a significant impact on MSFS 2020. I will write about its impact on MSFS 2020 in another thread.
I had similar after 1.6.5.0 but after double checking I’d cleared all Nvidia, Direct X cache and rolling caches, and restarting PC I have now got back to the stutter free performance I had in the first SU4 Beta version.
First flight, low over London PG was a bit stuttery (graphics only, not audio) I’m guessing it’s re compiling all the texture caches and the rolling cache? But after about 10 minutes or so it all smoothed out.
I’ve tried again today and flown in a number of heavy PG areas and it seems to be fine, the best performance I’ve seen in any version of MSFS. 
hope it stays that way.

Tested the Beta today and wow, for me a great improvement vs SU3!
(first time shaders & caches must be generated, but when it´s done (1-2 short flights) it´s smooth as butter!)

I still have mixed emotions with the latest release. For the first two days I had micro stutters and heavy lags on rollout, then these have disappeared. It seemed all good then for the first time in MSFS career, today I’ve got on back-to-back flights dxgi_error_device_hung error. Trying to sort out that stuff, managed to finish a 2hrs flight, but now I wonder when’s the next one…
**EDIT** it seems like the issue came up again, but removing GSX just delayed it. Not sure what’s causing it but both GPU Mem and Swap File being overused. Modified my post below.
SU3 did not have the performance improvements that I was expecting, especially with regards to CPU main thread optimization. I have not migrated from 2020 yet because performance has been way too unstable.
SU4 was a game changer for CPU performance and stability. There are still some areas they need to work out, particularly the VRAM usage, but it is not at a point where the sim renders unplayable like before. Definitely a step in the right direct
That being said, when I first jumped into SU4, I was doing great if flying around, but started to notice some serious issues when sitting on the ground for some time while setting up the preflight. I like to switch cameras and look at the outside of the plane, pan around, see what GSX is doing, etc. I kept messing around with my settings trying to ensure I was deconflicted between the NVIDIA control panel and the SIM. I kept adjusting graphics up and down etc. After a while on the ground, the Graphics Queue would shoot up and turn purple along with my Async Compute Queue, with no recovery. Pausing the sim would not help. I could not figure out what the issue was but as soon as I was in the air around 15,000FT, if the sim performance allowed me to take off, I could go into the pause menu and it would recover. Smooth as butter. As soon as I arrived at the gate and began deboarding and looking around again the spikes would come back again with no recovery, so it seems to be something ground related.
Today, I read @AcTiOn942MeDiC’s post about GSX, I really did not think it would be the culprit as I’ve never had any issues with it. I uninstalled it, and there was significant improvement in delaying the performance issues associated to the GPU, but I still have the excess VRAM usage issue, and it creates some stutters on the ground when panning and moving, but it recovers immediately. When getting ready for the takeoff roll, I get the spike again and it stays there until reaching some significant altitude. It stays solid purple with the timings for both Graphics and Async in the 100ms range. Not sure if this was the case before as I haven’t ever even had performance anywhere near being able to make the sim playable.
Either way, I am very happy with the progress, and if the performance remains the same on the live build and they can sort out this VRAM issue, I will finally be making the long awaited move on my end. If anyone has any tips or suggestions on a workaround to prevent the issue from coming up let me know.

R7 5800x

I suggest not switching to MSFS 2024 on the basis of a currently well-performing beta, as this can change drastically from one build to the next, and would suggest waiting until SU4 is formally released before reevaluating and, if still good, fully committing then.

Original Release
Performance was generally good for me. I could complete free flights and career mode missions most of the time, with only the occasional crash.
Sim Update 2
This was a major step backward. I began experiencing frequent CTDs with the popup message:
“Error: DXGI_ERROR_DEVICE_HUNG (0x887a0006)”
I attempted numerous troubleshooting steps with no success, including:
-
Monitoring component temperatures (all normal)
-
Lowering graphics settings to low/medium
-
Disabling multiplayer and AI traffic
-
Using a single monitor setup
-
Removing all add-ons and clearing the Community folder
-
Full MSFS 2024 reinstall
-
Testing with no peripherals connected
-
Clean driver reinstalls (CPU, GPU, motherboard)
-
Disabling RAM EXPO in BIOS
-
Disabling HDR in Windows
-
Disabling hardware-accelerated GPU scheduling
-
Formatting SSD and reinstalling Windows entirely
Despite all of this, the CTDs persisted in 98% of airliner flights (default aircraft, Fenix A319/A320/A321, FBW A380). Crashes typically occurred during cold & dark startup, pushback, taxi, and descent. Even when I managed a successful departure, I would almost always get a CTD on approach or taxi. GA flights were sometimes completable, but only after multiple failed attempts.
Sim Update 3
Unfortunately, the same DXGI error and CTDs continued despite re-trying all the above troubleshooting and even downloading content to my library. At this point, I had nearly given up hope—until SU4 Beta was announced.
Sim Update 4 Beta
-
I performed a clean reinstall of the SU4 Beta, and re-applied my medium–high custom settings.
-
Initial testing (without any add-ons) went flawlessly—successful flights with no CTDs, even at larger airports with heavier aircraft.
-
After nearly a week of testing across various airports, regions and aircraft (including the Fenix Airbus family), I’ve had zero CTDs and a smooth, stable experience.
-
I then reintroduced add-ons (Beyond ATC, FSLTL traffic injector, vPilot/VATSIM flights) and still experienced no issues whatsoever.
-
For the first time in many months, I can complete full flights: cold/dark startup, pushback, taxi, takeoff, cruise, descent, landing, taxi, and shutdown—with AI/live ATC and traffic.
The sim finally feels as it was intended to be experienced, and I couldn’t be happier.
Final Thoughts
When MSFS 2024 works, it’s truly breathtaking. Stability has been my biggest frustration, and I persisted through many setbacks because I believed it could get better. With SU4 Beta, it finally has.
A huge thank you to the Asobo teams for the hard work and dedication that made this possible. Please ensure this stability is maintained with all future versions and please don’t let the dreaded DXGI CTDs return.

That’s my plan. Assuming that the public release build is in line with the beta, I will make the move
Performance seems good on this build, similiar to the first iteration. I did however have to clear shaders, WASM, cache etc to restore the performance from build #1. However, significantly improved from SU3 where I coudn’t complete a flight over an hour. Would still like to see more improvements for microstutters when panning the camera, but overall significantly better.
Have been doing so careful study of the ILS BUG today which led me to do multiple approaches at KSFO a very complex airport and I was running 90-110 FPS with my 5080 in a B-787. I am not sure why a lot of people are getting bad performance but one word to stay off any instrument approaches except RNAV and I am not sure what else is affected in navigation.
I am sure Discord would kill performance, but I have also noted the Firefox does but not Chrome. I try to shut everything down. But a hidden factor can be OneDrive. If you like can set to pause for 2h while you fly. Finally, I set the FS routinely (defaults to) High Priority in the Task Manager Detail. This cannot hurt.
Clear Skys.
