10 second stutters when moving camera at Aerosoft Oslo ENGM after cache clear

ISSUE DESCRIPTION

Description of the issue:
I use Aerosoft Oslo ENGM (i think version was 1.0.2 or something), installed from Aerosoft One Launcher. I also use the Aerosoft VDGS dependencys and a GSX Profile from flightsim.to, that supports Aerosoft VDGS.

Whenever i am at the ENGM Airport, i have rythmic stutters codependent of camera movement. With no camera motion and no airplane movement, there are no stutters and around 80-100 fps. When i first move the camera after waiting for a minimum of around 10 seconds, the intial movement has a 0.5 - 1,5 second stutter (main thread shows red). After that its instant back up to 80-100fps.

When i let go of the camera and move it again after 2 seconds (so not wait until the 10 seconds), there is absolutly no stutter and everything is fluent.

I am talking about very slow movements of like 5 degrees left or right. The stutters do not care wether i am looking onto the cockpit ground (where absolutly nothing else is visible), or if i am looking at the terminal with many objects.
So please keep in mind, that i am not talking about 180 degree turns in quick motion. I know the limits of the sim and my setup and this is no performance issue.

Also worth to mention, that when i keep moving (either moving the camera very slightly in circles), or when taxiing, there is one 0.5 second stutter every 10 seconds (not exactly 10, i always head counted, but always 10-15 seconds).

Every other time, my fps is completly up. Even when flicking the camera quickly around i have at least 30-40 fps.

I did also notice that for the Salvuz Bergen Airport. Not sure if this is a compatibility issue, or has something todo with the sceneryindex, or something else.

When i take-off btw. the stutters vanish completly (like already at 300 feet they are fully gone).

Tested also with the newest M’M Simulations Tromso Airport, absolutly no stutters there. In general these are the only stutters i have in the sim.

Did you experience this issue before you joined the Beta?
I did encountered this kind of stutters already in 2020 and 2024 before. They were gone for a long time, but now they are back. I always noticed them first after clearing shader & scenery caches.

[PC Only] Did you remove all your community mods/add-ons? If yes, are you still experiencing the issue?
No, as this is a third party issue (at least until someone can confirm he had same behaviour at native airports)

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)?
Currently always at Aerosoft ENGM, but i can’t tell how i fixed it the other times. Often it was said it would be 3rd party application issues, but as i only have it at certain airports, i can’t generalize this. Afaik it always first appeared after cleaning caches (clean shader cache, clean LocalState cache, clear sceneryindex and simobjects and streamed packages, directx cache, rolling cache)

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

  1. Spawn into Aerosoft ENGM with Aerosoft VDGS Tool installed.
  2. Clear the caches mentioned above
  3. Restart PC
  4. Spawn again into ENGM
