You will get stutters in MSFS 2020 as well when you land at an airport, if the graphics settings you have set in MSFS 2020 are beyond what your hardware is capable of rendering smoothly for that airport, and the add-ons you have used for that airport.  It's just that with MSFS 2020, the hardware requirements are lower than MSFS 2024, so more computers in 2025, are capable of handling the graphics requirements of MSFS 2020.

For people that think MSFS 2020 has the same hardware requirements as MSFS 2024, it's not true. Go check the hardware requirements of MSFS 2024, it's higher than MSFS 2020.

I agree 100%.  For the same level of settings, MSFS 2024 requires more resources than 2020.  However, this does not mean that insufficient hardware resources is the cause of every performance issue.  Throwing hardware at performance problems is as old as computers and it continues until today, I know, I came from this world.  If this specific stutter issue were much broader, I would point at the hardware as well.  But this is not the case.  I don't see any stutters in any other phase of a flight on the ground or in the air.  It only happens in the last approximately 500' AGL in any airport.  I don't have custom sceneries of any kind and the problem continues to occur regardless of airport (the last two times, it happened at KBDL and KFLL).  My Community folder has only Fenix, PMDG and Navigraph.  Any activity in airports, including takeoffs, has no stutters.  Takeoff from a runway, no stutters, land on the same runway, stutters resulting in a real ugly landing if you want to call it that. 

I have spent a lot of time tuning MSFS 2024 performance and this has yielded very good results except for this landing stutter issue.  I never tried using Dynamic Settings per some of the negative comments I had seen in the past for this setting but now I am going to give it a try.  I do understand the downside of this setting.  My personal belief is that the performance of this segment of a flight is optimizable, hopefully SU4 addresses this via application optimization.  Thanks for the feedback.

It's been explained before by the MSFS team, but in nutshell, it's because of the huge increase in polygons being rendered when you land a plane at a complex airport.  The polygon count increases significantly, which causes the stutters.

In laymen's terms, almost all the graphics you see in a 3D game are polygons.  The polygon count is lower at cruising altitude, but it's usually the highest on the ground or near the ground, especially at complex airports. I also explain it here:

You can also refer to Roman Design's comment, who has developed several Canadian airport add-ons for MSFS, where he explains how the polygon count can affect stutters when you land at complex airport (especially the complex handcrafted airports):

So what’s the fix then? Or should we just accept that it is that way? And why is this not the case with MSFS 2020 or X-Plane? If they know what it is, then why don’t they do something about it? Or is this never supposed to be a proper flight simulator? The landing is by far the most relevant and fun part of the entire flight. I don’t want to accept that it can’t be any better.

I wouldn't waste my time flying a sim that gave  stutters on landing at a big airport. Sounds like something you would see in a sim 20 years ago..

This is odd. So far, I haven't encountered your issue. The only time I did was when I had Fauna enabled, once disabled, I haven't had any issues while in short final.

The fix is to wait fur SU4 release - at the moment it's looking quite good.
The current betas (beta 1 and beta 2) completely got rid of micro stutters for me (on a very fast PC).

...and it's also happening at non complex airports, explain that one...

Might not be that simple, when some people, even with very similar systems and settings, are having very different experiences.

An example would me for instance, for whom those last minute stutters appear to be gone on my system, making me doubt I need an upgrade from my 4070ti, while up the ladder, somebody with a 5090 is complaining about a slideshow.

The fix is too wait for Asobo to fix it, as stressed already this wasn't happening prior to SU3. Something changed for the worse, it's got better in SU4 beta but it still needs work.

A slideshow would be greatly exaggerated. Actually, I have a very smooth experience (as you would assume with a 5090) but still these occasional 1 or 2 heavy stutters on final. Doesn't seem to be much, but in this stage of the flight it really kills the immersion. But I agree that things are at least getting better and the SU4 better is a very good step in the right direction.

Fauna or no Fauna makes zero difference.

Edit: Hang on in there I had it off after reading about this as a potential fix and yesterday when I had really bad stutters it was on again. Maybe it is connected. Have to keep an eye on it.

Untrue. I had it from the very beginning. It got worse with SU2 and a little better with SU3.

I actually wasn't talking about you specifically, and didn't even know your system specs until this comment caused me to take a look. 😇

I think a video with RTSS overlay might be helpful here.  Long frames don’t bother me (as in makes no difference to my landing and input) so long as they aren’t more than about 80ms.  Might be good to determine the actual duration of the “stutter”.  For example, if I’m running 60Hz monitor so 16.6ms frames and I get some 33ms frames, that’s not a big deal for me … but for some that might be jumping off the building kinda deal … hence why I would be interested in what is consider a “stutter” (which is likely to vary by individual).  

Asobo have the tools to determine what might cause long frames … heck if you go into dev mode you might be able to ascertain.  

If RTSS isn’t sufficient (100ms logging), migth want to try other tools like Intel PresentMon or nVidia’s tools to log output and then match that to visual and run thru frame by frame to see visual identify the source of the long frame(s).

Turning on Dynamic settings is not for me, visual image quality is far more important to me than the occasional long frame that has no actual impact to my flying.

Ok thank you, it's certainly new to me since SU3 and that's when I started to see a lot more reports about it.

It does happen with MSFS 2020 as well.  I explained this already in a previous comment:

Assuming you aren't running other unnecessary programs in the background that add additional stress and workload to your CPU, GPU, and RAM, the fix is this:

1) Reduce your graphics settings until you don't stutter at the complex airports you land at anymore

2) Wait for Asobo to optimize MSFS 2024 further so that it runs more efficiently

3) Get better hardware

Most people don't want to pay for better hardware so 3) is probably out the window. Which leaves 1) or 2).  And if you are running other programs in the background that are unnecessary, just close all those programs and stop running them. This includes any browsers you have open as well.
