I tend to think its performance related. I'm running 1440p and not 4K and DLSS, no AI traffic and so forth. And don't have these problems except in extreme scenery areas.

I agree this is an issue that Asobo needs to address. No other program on my machine even 2020 has this issue. Please better optimize 24, a 4080 with a 5800X3D and 64gigs of memory should not have this issue.

may be anecdotal.  But I had tons of these spikes from time to time.  I've noticed they have largely gone away since right around the time I went from 32gb to 64 ram.  Not saying one caused the other.  Just sharing. 

I did two flights yesterday in the PMDG 737-700 on MSFS 2020 using VATSIM and ActiveSky, one over the Rockies from Montana to Wyoming and one from Honolulu to Lihue. The flight over the Rockies was a stutter fest and the flight over the ocean did not have a single stutter. I am starting to wonder if it is tied to data downloading for scenery tiles, I wonder if 24H2 changed how it delivers data to MSFS. One other thing that I have noticed is that I have a super smooth takeoff and landing, stutters seem to be bad at >4000'. Prior to both of these flights I removed my overclock to see if that had anything to do with it. Prior to the removal with RyzenMater, the max temps I saw was 72*C after the removal it was 61*C so I don't think it had anything to do with the OC. 

 

I am debating on re-installing Win 10 since I have seen that people are also starting to see the same issues with the stuttering on 23H2.

I don't use on board MB sound because it adds more work for the CPU. I use sound blaster card that has it's own processor and let my system CPU handle other processes.

Hmm... I haven't thought of that, but it makes sense.  Less work for the CPU eh?  I gotta look for that recent sound blaster card someone gave me and now stored somewhere and try it. Thanks for mentioning this.

Hmm, was in another thread, possibly one of Noel's where I also mentioned having these small audio cutouts or just quick hiccups. It was, oddly enough, worse at cruise (In the Fenix) and that's almost where the CPU was the least impacted. At airports, will full traffic and a town around, everything seemed okay. This was 2024, I'm running 64GB of RAM and an external audio device (Roland Bridge Cast). I think the issue is to be found either in the sim itself, Windows update or something beside a personal hard- or software issue. 

I’ve had this issue of spikes and stutters as well on my system (5800X3d, RTX4080 Super, 32 gigs ram) running 2024. My flights did not involve LAX, instead, departing DD’s KDCA and over the quite complex scenery of the DC metro area. I found the severity of the spikes and stutters varied considerably by aircraft. With the steam gauge default C172, there was nary a stutter at all. Also, when flying the A2A Piper Comanche, the flight was very smooth, even though this is a quite complex aircraft. The worst results were obtained with the Blacksquare Analog Bonanza. In this complex scenery area, the Bonanza produced a stutter fest. So, while it is possible to fly the 2020 BS Bonanza in 2024, it would seem that it needs some optimization before it will perform nicely in complex areas. Your mileage and results might differ from mine.

I'm getting this like crazy in 2020. Seems to be a recent thing as well. Never had the issue. Wonder if this is a MSFS thing, Windows thing or Nvidea thing. It seems like its the sim that is indicating a spike.

Okay I added a sound blaster sound card to my PC just to remove the CPU load on sound. The sounds do sound better and everything seems a lot more clear with the sound card. But the issue still was there. CPU spikes still present. So this definitely has to be a a Asobo issue, or a Windows 11 issue

You're on stage 1 😄

Running a 5800X3D with an RTX3080 with FRG and AuroFPS plus 32GB RAM and I am having the same issues.  Also the GPU fan is running like the clapoers nearly all of the time.

It's really tempting to go back to MSFS2020 until ASOBO can get MSFS2024 into a non beta state.  The fact that MSFS2024 has been released in this condition in nothing short of disgusting.

I run 2020 smoothly in ultra whilst 2024 is a stutterfest in high settings and barely looks any better than its predecessor to me.

I'm pretty sure that most of the recent 'sound spikes' are just the sonic partners to breaks in the sim stability and are linked to peaks and occasional overloads in the server infrastructure.

I've been determined to get to like MSFS2024 (I'm pretty much 100% VR and VR in MSFS2024 is presently 'a challenge' ).  As part of that, I've spent pretty much 3 full days fiddling about with settings in MSFS2024, comparing and recording the results to MSFS2020 and noting what settings I've changed to what. 

And, like we all do, assumed that the crackles and then stutters were related to my own settings and equipment.  But there was a pattern, highlighted by a couple of days ago which brought my testing to a halt.  It was shortly after I'd done the 2.5GB update to MSFS2024.  My update went OK.  Half a day later, after changing lots of settings in MSFS2024 and all the supporting software links and packaged the the stutters, pops and crackles started.  To a point that it became unusable.  What had I done?  Should I revert to the previous settings?  In the end I just switched it off and went to bed.  Following morning, turned it back on ready to reset and start my process again - but, without changing anything, all was splendid.  Almost certainly, the pops, crackles and stutters were the effect of the update going round the world, with folks downloading it, trying it out, all over the place, all over the same time periods.

And the last time I got similar pops, crackles and stutters?  Yesterday evening...that'll be Friday...when gamers throughout the Western Europe server catchment were switching on...

This morning.  Smooth and perfect.  Same sim.  Same settings.

I'm using headphones with Sound BlasterX G6 DAC/Amp connected to USB-C, Win-11 24H2 and haven't noted any sound problem with 2020.

+1. I am experiencing the same......at the same times as you.....I am located in EDDF

Serverwise performance IS in my opinion influencing the sim performance incl. sounds!

It's my impression as well. I get random FPS drops and frame time spikes (and audio cutouts) even though I have more than enough FPS headroom.
