I was also facing drastic fps drops and stutters after the last MSFS update. I have updated my Nvidia Driver to version 457.30 , which seems slightly to reduce the stutters and gained fps.

Worths a try. It is recommended to you also, if not done yet. Happy flying.

Thanks for the note .I don't think this is related . actually this issue was visible since patch #5 but it got bit worse with patch 7

It happens indeed on every airport. The degree of its severity depends on the airport , for example is very noticeable in EDDF or LFPG or even Aerosoft EDDK. Did you vote comment on the thread? We need to make a fuss about it .

However what really puzzles me , does it happen as well to the rest of us? @pmb mentioned that he didn't notice it . It could be visible if you are GPU limited 

Have voted

For me this happens in 4K, not really in lower resolutions. I have driver 457.30 and a 2080super. I have 35 to 40 fps at medium altitude (maybe 2000 feet or so) but when I go down with aircraft or drone the fps can reach low teens. I found out that this phenomenon is much more pronounced when photogrammetry is activated and is worst when there are autogen trees on top of photogrammetry tree polygon thingies. With photogrammetry off it's much less much still there at least in areas with lots of trees. In my case it's always GPU limited, almost never main thread.

Maybe someone could try a region with very few trees (I recommend Arizona or Egypt 🙂 ). Does this reduce the fps loss?

But the issue is that when reloading that same position (with bad framerates) the framerates are high again.

Very strange

I sometimes (not always) have that too. I restart a flight at a small airport (maybe near Atlanta) and fps while taxiing are over 35. Then I fly a bit and land at the same airport and fps are down to 16 again.

yeah that is exactly what some of us having here and the that is what the is this post about. It gets frustrating if you are landing on an airport that is heavy like EDDF. LFPG or high fidelity third party airports like EDDK or LOWW. Again please comment and vote here: https://forums.flightsimulator.com/t/low-fps-after-landing-on-airports/330541

I don't see that extreme drop in fps while taxiing as the OP. However, I noticed a general drop in fps as well as more stuttering (if I let fps free floating). I also observed being "Main Thread limited" now while I have been "GPU limited" since alpha days and until recently.

Thus, something definitely changed, and not to the better.

Kind regards, Michael

Thanks for the observation. Indeed there is something has changed, I think the stutter to this issue is somewhat related. 

I renamed the Community folder just to have a clean sim from any mods (god I love this system of the community folder :D). Anyway, the issue is still replicable, a screenshot after the teleport:

I think you're on to something here...similar settings and resolution. Perhaps worth a zendesk if you can reproduce as well.

I think this issue it does happen whenever there is a location with heavy 3D models involved, for example if you would try it on a default airports , you won't notice this issue much but however the moment you would have a third party airport for the same airport that has a lot of details, then the issue is visible. I think when people complained about EDDF or LFPG it was this issue but nobody noticed it in other airports with more details until the recent patch which is now visible in other airports as well .
