Looking for Tips to improve long pause stutters

Looking for advice on how if even possible to reduce bad sim stutters that last a second or so when loading in complex 3rd party airport scenery. For example last night I was departing from FSDT KIAH I get really good performance until I hit about 500 feet and it loads in the 3rd party KHOU scenery causing a long pause stutter or 2 then happened again when overflying the KAUS airport at 36000 feet and then lastly descending into OKC loading in the inibuilds scenery. This happens regardless if I’m in a 3rd party airliner or a light GA aircraft. Once the assets load in frames go back to normal

My specs are Win11, Asrock X670E Taichi, 7800X3D, RTX4080FE, 32GB DDR5 6000 RAM, SSD dedicated for MSFS and a 240HZ 1440P Ultrawide 45" LG ultra gear Oled.

I ordered a new 64GB ram kit to see if that helps any. As for settings I run a mix of high and ultra with things like clouds and Texture quality set to high. DX12 with frame Gen on, Gysnc Off due to flashing, TLOD 180/Object LOD 200(reducing these a little doesn’t change anything) I dont use Photogrammetry or AI air traffic, just FSTL models for Vatsim model matching. And the only programs I have running along side the sim are usually just V pilot and Navi graph sim connect. I built this new system to avoid stuff like this while being able to maintain nice visuals and while I’ve been dealing with it for almost a year its become more of an issue now that I’m mostly flying on vatsim and things like bad stutters right after departure cause issues when trying to Fly a SID and stuff.

Have you tried clearing your Shader Cache? This works for me, and I try to do it once a month or so:

i’m pretty sure this is the problem right here

i wouldnt worry about it, 2024 is a month away and very likely this kind of stutters proble will be greatly improved, AND it will have model matching of its own (allegedly)… so you wont need fstl

To resolve the issue you’re experiencing, I recommend starting by clearing the MSFS and Nvidia cache. This is often a good first step in troubleshooting.

You can find the correct instructions by expanding the section titled “How to delete MSFS and Nvidia cache”. Follow the steps outlined there to properly clear the cache

How to delete MSFS and Nvidia cache

13 Click temporary files > scroll down > check box DirectX Shader Cache
14 scroll up > click Remove Files

15 Restart PC.

16 Launch MSFS.
Delete rolling cache.

Next, test MSFS without any modifications. To do this, rename the Community folder to Community_copy, then create a new, empty Community folder.
Also rename exe.xml to exe.xml_copy

Launch MSFS without running any external applications like FSUIPC, FSLTL or similar software.

In the MSFS graphics settings, set to Ultra Off Screen Terrain Pre-Caching.

Also, make sure to disable traffic in the MSFS settings. This includes AI,
,live an multiplayer traffic.
Once you’ve made these changes, be sure to save them before testing MSFS again.
