Hello,i dont know why i have this crazy fps situation…im on pc,steam,and time to time huge fps (from 40 to 4/10)as im not the only one exprience this.But after i put the sim in windowed mod the graphic card or the cpu,not sure restart working as normal with normal power and of course its down again and if i switch to fullscreen happen the same thing.
I dont know if i explain myself,here some pics.i think it is bootleneck…
You have very high VRAM usage, what GPU do you have and what sim settings do you use?
And this airport is it an addon? Does this happen at other airports too?
Basically when your VRAM is full and the GPU needs textures that don’t fit in the VRAM it has to do something to get the textures elsewhere. Maybe this addon airport has very large textures, i have had problems with some badly optimised addon airports too.
it’s 4K HDR 
…
but yes, we need some additonal informations which are requested in issue-template.
ehy,thx for the answare first,i have rtx 2080 ti here are my setting pic,and tes the airport is an add on but happ
en even when i fly,but time to time.
could be the airport but happend also in a vanilla one,could be anothe addon…i have alot of them
Try turning off live weather. Yesterday I was at 20 fps solid all day, this morning I was getting 9-11 fps, turn off live weather and its back to a solid 20 again…
i think the vram is the problem as u say…now i have 10gb usage out of 8…so the gpu cant handle it of course
on ground there is often a very high load… it seems you overstress the 2080TI. The problem is, there is a high range of performance requirement in that game. I own this card too, but have only “near 4K” 6MegaPixel instead your 4K with 8MegaPixel ( with add. HDR on ). In most situations the game works pretty well , but I not wonder about that I get sometime bit lower fps on ground. The 2080TI is just not the newest GPU
So, just try to lower the settings a bit 
yeah just did some setting change and the result is the same,i think the add on is the problem,im gonna removit and give it a try
Okay that picture with the GPU dip is probably full VRAM probably because of the addon, i have it with multiple airports and i have 12GB VRAM. Some devs use huge textures and no optimisation or compression, you have texture resolution on Ultra so it’s taking up a lot of unneeded space.
If you have problems in flight it’s likely a different cause, there are multiple different performance issues with MSFS. Check what your “GPU Mem” numbers are. If you get “Limited by Mainthread” instead of “Limited by GPU” it’s likely another issue. There are currently a lot of topics on various performance (degradation) issues in the forums.
Yes which airport is that from which developer?
I dont have the scenery but near 18:57 in this review video there is a big freeze does that look similar to your problem?
yep preatty the same
Ok so the scenery seems to be the problem unfortunately. Not something you can fix.
Other problems during flight are things we all experience sometimes but are mostly not GPU related.
yes,really…thx again
