Many to most have had varying degrees of this since launch, but prior to SU12 I rarely to never experienced this since my optimizations done in 12/2022, which began with a Win 10 and MSFS reinstall, and morphed into other changes as described ad nauseum here.  Yesterday, I did KSLC>KLAS (FlyTampa) in the PMDG 738 and had modest stuttering from maybe 5 miles before touchdown so was acceptable though still a loss of the nirvana previously experienced for 3 months straight.  This might have been secondary to main thread stress, but not sure.  Then rebooted (I do this between all flights now) and did KATL>KSMB (not particularly demanding arrival) and despite have huge headroom in main thread, GPU and VRAM, had massive stutters w/ inability to maintain frame rate--have not seen anything like this ever.  I could barely land the plane.  After SU12 noticed this happening so rebuilt the rolling cache, cleaned DX Shader Cache files, etc, to no avail.  Near as I can tell all of this started w/ SU12, though Win10 did a couple of updates so perhaps there is a possible culprit.

I guess I'm trying to learn how widespread this is, and if SU12 marked a major worsening for you as well.  If you noticed this issue became markedly worse after SU12, did anything restore prior behavior for you?  Since I'm seeing this as likely secondary to SU12 I'm trying to avoid a reinstall of MSFS as I didn't change anything w/ my basic configuration, but again maybe a Win10 update did this.  Today's wretched arrival into KSMB, and others like it, are tempting me to start fresh again w/ a fresh Win 10 and MSFS install--but i just did this in Nov 2022 and would rather avoid it!  I did update a GPU driver to the latest just yesterday, to no avail, as is typical w/ GPU driver updates.

 

I've been experiencing this issue since day one I installed FS2020. I posted this issue on Asobo support forums many times. They know it's a problem. I was hoping it would be resolve with the last few SU updates, but it still happens to me. On user on their forum suggest resetting the data connection in the option menu on approach clears the mass stuttering slide show. I tried it and it worked, which tells me that Asobo server is not releasing or refreshing data during long flights. Even though you have all the headroom on video and system memory, FS will not refresh and use your system resources.

Recently on my system, I flown all day Sunday without a issue after last update. yesterday and today I cant get FS to even start up properly. I get a UI with no options. Go figure.

Same here.  Stutters on departure of small, custom caribbean airports.

I usually have decent locked fps at 30 and most of the time it's fine. Sometimes, even in a small GA plane in a small GA airfield....I will get major...major stutters on final. Sometimes, this doesn't happen at the same spot, time and plane.

This can happen in a higher-fidelity planes as well.

That's pretty much it for me with a lock around 34.  Did this increase or start w/ SU12 for you?  What's odd is that so far a majority of others aren't seeing this but rarely.  Funny thing is departure no matter where or in what plane, hifi planes, no problems at all.  I left on a road trip a little over 3 weeks ago hoping somehow it would resolve itself, based on the idea it is something on the other side of my internet connection, but no joy. On my KLAS-FT arrival about 8mi out I started getting subtle stutters despite main thread hovering around 60-70%, so Alt-Ent twice to toggle windowed mode and this abruptly stopped the stutters, and the taxi in was very stutter-free.  Very diff to troubleshoot and at this point I don't know where to turn and it is a show-stopper.  It does leave me wondering if once again I should start over and reinstall Win 10 and MSFS w/ it's external addons.  Will wait and see how the poll proceeds.

I am also having these stutters upon approach just recently after a complete reinstallation. Today I took a flight in the ATR from Cairo to Luxor and when i started the flight and got into the flight deck, the FPS were really low (not stuttering though...) I changed to the external view and could not believe my eyes - MSFS had spawned a PDMG 737-800 Cargo in ASL livery and an Aerosoft CRJ as static aircraft. No wonder the frames were low with these models on the ground. I reloaded the scenario several times and could see several diffent aircraft types from my installations. I was not aware of this previously tbh.

Here is  a screen shot after i reloaded - again a 737-800 Cargo, this time in PMDG colors: https://imgur.com/a/Pq9VEQC

I've went into General Options - Traffic and set the GROUND AIRCRAFT DENSITY to 0. Furthermore, there is an option USE GENERIC AIRCRAFT MODELS (AI TRAFFIC) - This was OFF in my settings, probably allowing the PDMG and other models to be used in the first place. I can see the additional load when approaching especially bigger airports if these options are active. I just took a flight with GROUND AIRCRAFT DENSITY = 0 and had stable frames when landing at Luxor. Maybe worth checking out...

Are you using FSLTL?  I can say closing down FSLTL during final approach does not prevent what's happening I'm pretty sure

Well, I just had the FIRST nirvana flight since SU12, subjectively and corroborated by CapFrameX w/ ultra low FTV and Stuttering:  PMDG 738 KRNO>KSLC.  Four things were different on this test flight that I can think of:

1. Changed USE GENERIC AC MODELS to ON.  Of note, this has always been OFF.  Perhaps something in SU12 changed what this does, as you suggested allowing 3rd party plane models to be used.
2. I probably should be embarrassed by this, but sometime around the release of SU12 I connected a 2nd monitor to access Intel Integrated Graphics which the 9900K does.  I set them up as separate displays, my main display connected by DisplayPort to the 3080Ti as it has been, and an older Dell 19" to the on-board GPU connected by DP on the motherboard.  My assumption has been they don't interact so should not impact performance, but perhaps that's not the case and they do!  I just remembered this major change.  
3.  I did not start ProcessLasso as I have done since optimizing in 12/22 with no untoward effects previously.
4. I changed a setting under Gsync Setup in NCP from Fullscreen Only, to Fullscreen and Windowed Mode.  It's possible I changed this sometime in the recent past as I've looked at many areas as potential culprits.

Time for another test flight!  I think I will reenable the 2nd screen first and see how it goes...

I wouldn't reinstall anything at all. In fact, I'd say reinstalling anything is a complete waste of time. Deleting shaders, uninstalling some freeware/payware mods and resetting NVIDIA CP settings (then setting them back after a restart) seems to fair better. Reinstall of everything is too time consuming with little benefit.

I lowered my LOD and TLOD back to 100 and keep AIG traffic to 50% and GA traffic to 10% (I know it hogs) and it helped. Oddly....when all payware/freeware scenery and all traffic is turned off....sometimes it still happens even in lower fidelity airfields with GA planes.

Yesterday, I flew the ATR from LOWI to LIRF and everything was perfect until about 150ft from touchdown. Absolute ****ing stutter fest. I went from a locked 30fps to 5fps out of nowhere. Today, I flew the same route but from LGKO (Island in Greece) to LIRF. All of these were payware. The last flight did not have any stutters on approach, final or flare etc. I was kind of scared during the final since the stutter fest happened the day before. There was a slow down but I don't leave developer mode on during my flights because I'm an word not allowed and like to log my hours. Haha. The slowdown was small or next to nothing. No changes in settings.

Conclusion: I think this is an Asobo issue mostly.

 

PS I have a second screen as well. I use this for Pilot2ATC, AIG settings, Navigraph charts and general browsing (youtube) etc.

And it's always possible there are more than one factor influencing this behavior so very diff to nail down.  I will try my next test flight w/ the 2nd display connected and see if we have another Nirvana run.  FTV 0.2ms at 99.4% over 58 minutes of flight including landing and taxi at KSLC it's literally been since around SU12 release I lost this completely even on the "good" flights w/o massive stuttering on arrival have not had this sterlingly low FTV which equates to ultimate smooth animation.  🤞🤞

I had this issue once many months ago flying into PAKT where I land frequently even tonight with no issues.

The best part about MSFS is that we can always blame the online severs even if it makes no sense.  Not worried about it.

Cheers

Prior to a major update of my PC to a AMD 5800x 3D cpu, and Radeon 6800 i constantly had stutters or long pauses on approach at most airfields.Since the upgrade last year, thety are pretty non existant.

Yes, with TAA in VR, I have a weird issue of constants stutters only when I move the aircraft when in ground or near, and I am in the VC. No stutters at all or almost when I do not move the aircraft but moving my head, or in the exteriors views moving with cursor or drone around 360º, smooth without stutters, strange: disabling Multiplayer and Live Weather in Sim DATA options, then rebooting Sim, cured the stutters not the problem because I want ofc fly with those settings.

In my experience this is heavily dependent on my settings, which plane and which airport. It is not a severe problem for me most of the time, but it certainly does occur from time to time.

I am minded to put some of it down to my use of FSTL traffic loading on approach rather than the sim itself, although I cannot confirm that. It is no better or worse for me since SU12. I have not compared the experience with no addons or traffic. That's the only way to really tell whether this is down to the sim or not.

Anyone done this test and still got stutters? Be good to hear. The last time I clearly remember some stutters was in the Fenix on approach to RWY 26 at Gatwick with FSTL a couple of weeks back.

Lower settings = problem solved.
