Yes, that’s the only reason I can imagine. It’s strange that it’s only for the shadow though, not the prop itself.
As I’ve said before, I’m surprised they don’t have someone with a bit of common sense checking things at an early stage, and not just in flight but in the UI as well.
It isn’t pointless to have 4K textures on a 1080p monitor though, unless you are speaking of very small objects (which wouldn’t be using such high resolution textures noramlly). Large texture sizes are usually used on large objects like the exterior of an aircraft/building. And if you are close to an aircraft/building you will only see a small part of the entire texture right? Which means that if the texture is of lower resolution you will easily start to notice pixelation even on a 1080p monitor.
And yes I can tell the difference, it’s not just in my head 
If I couldn’t tell the difference I would never bother to turn the setting up in the first place.
I would also like to say that if you are running the sim at a lower than native resolution (without upscaling) I can definitely see why it would look comparably worse.
Well I really wanted the higher rez to make a difference that was worth it when doing a mission. And it simply doesn’t.
However, if you like to zoom right up close to a cockpit dial, or get out the plane with the drone camera and position it a just few inches from a slab of concrete on the apron – then yes you might see some difference 
Just realized what a big negative performance impact fsltl traffic injection has 
I should show this to the developer of some code that looks in depth at these processes. We were discussing this AM. I take a routine flight every AM in my neighborhood in California between Reno and San Francisco that consistently show these problems.
I decided to purchase a 5080 and I can run at 4k at 50 FPS most of the way until the landing flare when the FPS drops to 44 or so… it is imperceptible… but shows you what is going on because at the same time the GPU and VRAM are at 50-70% capacity. The CPU is running no more than 30%. So there are weird things going on in their software like you suggest the propellers.
I think that is just for marketing… performance apparently does not sell?
Do you have the same issue if you follow the OP’s steps to reproduce it?
• I have the same issue. I am on Xbox Series X, so I can’t see vram usage, but after a few minutes of flight time, mesh quality decreases dramatically and the Sim hangs 1-2 sec every few frames.
Provide extra information to complete the original description of the issue:
• Have had it happen in C208, Twinstar, H125. Mostly while close to the ground and particularly in more complex environments (near a town, etc).
If relevant, provide additional screenshots/video:

I guess we are just different 
I found a thread on CapFrameX and it looks like it is legit to use this to check FPS performance. I put up some actual 5080 data showing stutters relating to CPU surges that cannot be explained by GPU or VRAM issues. FYI:
Yo…not saying this is ok, but…you need to tune your settings using debug display FPS , so that you dont exceed VRAM. VRAM eaters are Object levell of detail and Terrain LOD set both to 100. Turn off airport vehicles is another one. Down texture resolution to Medium first of all. Then down anistropic filtering to 8x from 16x, you wont notice the difference. Turn off FAUNA also, again unless you are rat hunting you wont miss it. Now see where your VRAM is at… keep it below max at the most demanding of airports with the most complex aircraft…then you will get silky smooth performance. Try not to think about when you are in cruise and you have 150FPS LOL. Or save yourself all of this agony and get a GPU with 24gb of VRAM (kidding, sort of)
This is from the Dev stream that just finished. It doesn’t not show the bug is fixed anymore, but I’m progress again.
Yep - it was said today that “SU2 was just the beginning.” I expect that this is something that will be ongoing in one way or another for the life of the sim as the “bug” for many users is simply poor optimization, which always has room for improvement.
Agree. This is encouraging. I thought SU 2 would be the best they could do regarding VRAM fix. The current SU 3 Beta is not “the worst” thou, better than the earlier days. However, the sky is vast, improvement is too
Good advice but not aware of a specific setting for airport vehicles.. just aircraft and air traffic. Have i missed something?
Correct, ridiculously just 1 slider Airport Traffic that controls parked aircraft and ground vehicles, yet everything else has it’s own slider.
I’ve not noticed Fauna have any significant impact on performance, but I turn it off anyway to avoid having sheep and cows grazing on the runway.
If using AI Offline, then ships don’t show up even the ships setting is set to Ultra. I hope Asobo will make all of these settings separate like they are in 2020.
That’s interesting, I will give it a try. My biggest issue with this is I just can’t seem to understand why Asobo would release a game that has this big of a problem. While the graphical improvement is noticeable, I do not think it justifies such an increase in VRAM. In 2020 I’m using around 3.5 GB of VRAM (in highly detailed areas such as O’Hare/Chicago) with my textures on high, 1080p resolution, and a similar MED HIGH mix on my settings. I will say when the VRAM is under control in 2024 I do notice the sim runs quite smooth and playable, but when the VRAM gets full the stutters and low FPS begin. So I do believe there is definitely a leak or a bug somewhere in the VRAM that the developers have yet to fix.
This has been discussed to death, but in case you missed it 
Asobo didn’t release the game, Microsoft did. And per representitives from Microsoft, they released it in a state they were very unhappy with - which is code for “my boss set a deadline that we couldn’t meet, but we had to anyway.” Since release they have published dozens of updates and already two major ones totaling in literally thousands of changes.
Launch sucked. The first 6 months have sucked for many. It’s also getting better for many, and with updates like SU2 and now SU3 in a short while, I would say better for most.
The MSFS aircraft are pretty lame so I am using AIG Traffic and they are nice but they also eat VRAM. FYI my Flightbeam SFO rendition made a big deal about adding seagulls.
They really need to optimize everything more and more, aircraft, airports, everything!
I was testing some planes with Dev mode. And all of a sudden i got that warning msg and i saw my vram was above 11gb, i managed to capture above screenshot. i am guessing vram jumped over 4-5gb at once here. An aircraft’s cockpit view caused this, pilatus pc-6. You guys can replicate it. I was at Ultra textures, ultra-high mixed settings, 1080p DLSS Quality. LICJ, just departed, 500m away from airport, over sea.
I opened “Aircraft selector” with Dev Mode, selected and activated Icon aircraft. Stayed on outside view.
Later i choosed Pilatus aircraft. Stayed on outside view.
And i switched to cockpit view of pilatus. Vram usage jumped over 3.5gb+ this time. I tested a bit more and vram jump was over 2gb+ always. 1st vram increase was crazy, 11gb+ vram usage is so high at that place LICJ, just over sea 500m away from airport.
Later i tested some more and i managed to capture 9gb vram usage with that cockpit view. Vram usage slowly drops in time but still difference is crazy for outside view vs cockpit view for same aircraft!
This is same exact place with default aircraft Xcub, 4.76gb
Difference between 2 aircraft is 4gb extra vram… They need to optimize everything!
AIG or FSLTL liveries are now working with the default live traffic in the beta. But AIG or FSLTL does work better with their injectors. However both AIG and FSLTL don’t work nearly as well as they do in 2020. Hopefully this will be corrected by the time SU3 goes final.
