Now that I have a high end CPU (9800X3D) and GPU (4070 S) I've found a whole new set of things to adjust.  I am on a 1 GB Xfinity connection and the system has 128GB of NVMe rolling cache.  

Sim is running at 75+ FPS with TLOD 400 / OLOD 200 / Buildings and Clouds at Ultra, everything else at High.  GPU is at 98% load but only 9GB of 12GB GPU memory is in use.  CPU is about 45% busy and only 28 GB of 64 GB system memory is committed.

Flying at 4,000' AGL in Idaho mountains I see a lot of scenery popping when I look out the side windows or switch to external camera.  Some of that scenery that pops into place is within a couple miles of the plane as it flies.

Is there anything I can do to eliminate or reduce the scenery popping into place?  

What about the "Off Screen Terrain Pre-Caching" setting? On Ultra? That should help a lot.

I have it on High now - I will try it on Ultra

I use Map Enhancement all the time but it has a huge cache and I seldom see any network activity if I stay in the same area.  In this case I've been flying around Idaho for a couple days.

If you’re talking about terrain morphing then it’s a well know issue and a part of the engine used by MSFS. It’s been mitigated in FS24, but if you look closely it still exists. Not as bad as MSFF2020. 

If you’re talking about the scenery/objects popping in to place then it’s the shocking aggressive LOD that msfs is using. Way worse in 2024 than in 2020. 

TLOD @ 100 for best results.

Are you using AutoFPS? 

I have a similar system to yours (same CPU) and I would get scenery popping into place and stutters when panning around at high TLOD. What worked for me was to lock the FPS at 60 and use the FPS Cap mode in AutoFPS, and set TLOD Base=50 and TLOD Top=400.  With that, I can pan the camera all over as fast as I can, internal and external views, with no stuttering or terrain popping. Base and Top TLOD are almost always higher than those minimums, but when MSFS 2024 is busy working hard, the limits get lowered to give it some hardware cycles to work with.

In other words, let AutoFPS constrain your performance to below what it can handle, creating headroom that can be used in high-demand situations.

I changed Off Screen Terrain Cache to Ultra - flying Idaho mountains I saw one brief instance of terrain popping into place about 5-minutes into flight and then no more popping at all.

What worked for me was to lock the FPS at 60 and use the FPS Cap mode in AutoFPS, and set TLOD Base=50 and TLOD Top=400.

Where do I lock the FPS at 60 ?  RTSS?  AutoFPS? Sim Graphics Settings?  I will try you AutoFPS idea.

I used the in-game setting in MSFS under Settings > Graphics > Frame rate limit: 100% monitor refresh rate. I have a 60 Hz monitor, so that ends up being 60 fps. In AutoFPS, you would use Expert Options > Auto Method > FPS Cap, and then set Target PC FPS Cap to 60. Note that this setting in AutoFPS doesn't actually set your fps cap; instead, you're just letting AutoFPS know what cap you set in the sim.

You have more control over the actual fps cap that you set, if you don't use the in-game settings and instead set a cap using another app, but I haven't run into a need for that. The in-game cap described above works for me.

Sorry if I'm a failure...
But I don't see any difference with the terrain pre-cache, whether it's on Ultra or Intermediate...

Where should I see a difference in terms of scenery?

And on FPSs, too, I don't feel like it takes up much FPS between Intermediate and Ultra.

For me is not really popping but I get this sound distortion when planning around after takeoff and during flight and at the same time frame drops. Then it's smooth again locked at 40.  I shouldn't be experiencing this with my setup and I have Internet speeds of 600mbps. This never happens with 2020. Any advice? Now I'm on the latest version of win 11 also.

Turn off dynamic settings in the sim if you have it on.

I had this start to get a lot worse along with the delayed cockpit rendering after SU4.  Yet same settings with SU3 - absolutely perfect.  I wish I could go back to SU3.

Some people say they don't really see either issue, but their perception of it must be different.   Every MSFS YouTuber video I have watched since SU4 shows it clearly.

Sorry to bring this older thread up.

So i primarily fly in 2020

So i decided to jump into 2024 for a flight.

And i noticed scenery morphing.

Its crisp but it pops.

Dynamic settings off

Pre cache ultra.

Settings high and ultra .

64gb rolling cache, deleted and refreshed.

1gb internet fibre.

Latest nvidia drivers

Win11 up to date

System 

9950x3d 5090 64gb ddr5 ram

M2 ssd x2 at 4gb each.

1500w psu

I do not use auto fps for 2024 only 2020.

Msfs 2024 i have 200tlod and 200olod

Thanks
