I disabled and deleted the rolling cache and the manual cache as well. This had two nice effects for me:
- stuttering disappeared nearly totally - instead of stuttering for 20 or more seconds all 5 minutes there are very rare stutters for 1 or 2 seconds
- the problem with disappearing trees while approaching them has vanished.
My internet connection is quite fast (up to 26 MB / second).
My PC specs are:

Similar for me, particularly after the update I was getting stuttering.
I deleted the rolling cache and reset it, and the stutters have pretty much gone.

Keep in mind that MSFS 2020 scales its overall performance (both visuals and fps) up or down depending on your hardware and internet speed. Watch some of the official MSFS discovery videos, specially the one made by lead engine developer Lionel Fuentes where he talks about how the sim takes into consideration your hardware and internet speed.
Yesterday I was watching a video made by a youtuber where there was a lot of jankiness at an airport he landed at. He’s got a nvidia gtx 1060 gpu and mine is a 1080ti. There was a huge difference between the scenery he has at the airport compared to the scenery I got.

You stated that you have the GeForce GTX 1050 Ti, and I have a suspicion that that too is contributing to the issues, and it’s not the sim’s fault necessarily.

You may be right … but the main thing for me is that things work better now, whatever the reason might be in some other case …
A better PC / Laptop is planned in 2 years, until then I need some workaround solutions.

Skip the laptop. your CPU is very good. Way better than mine (and I have no performance-related issues so far). IMO all you need is some more RAM and one of the RTX 3000 series cards. Heck…if you can find a 1080ti (which is what I’m using) or a 2080ti for an ultra-low price (and their prices should be going down now significantly), you will get amazing performance.

OK, i will think (and dream) about it. Thanks for your advice.
I have also disabled it and see no adverse effect. I will report later if I notice something noteworthy.
One point tp consider is that (unlike HDDs) SSDs come with noticeable CPU utilization, so it could have a detrimental effect.
Another reason for me is that constant caching is not exactly healthy for SSDs. It will not be a problem if you replace it in 2 years anyway, but write cycles largely determine the lifetime of an SSD, so it could be a problem in the long term.

That’s right, I don’t use it anymore. This is - regarding my PC specs - the best solution for me now and it works fine. I get constant 25 FPS, no stutters (and no disappearing trees anymore - the main reason for that change) and I’m very pleased with it.
