Oh I saw them even in DX11 with some remote airports that adobe never hand tailored. However, I have never seen them in big airports (I predominately fly in USA)

I suspect this may not be the same thing. What we are talking about here are disappearing textures. They are there one second and gone the next. Move about and they may reappear and some others may disappear. Happens at default airports, tailored default airports, freeware airports and payware airports. The ground textures just vanish. Sometimes they don't vanish at all, although that is rare for me.

I could be wrong but it sounds like you are talking about airports that may not have been textured to begin with and that would be unrelated to this issue. This is a problem with the DX12 implementation.

I do not have this problem! I'm currently is on DX12 I'm running RTX4090 DLSS on quality.

No, not everyone does.

it seems like no one with 24gb VRAM has this issue...

You don't know that.

And why should someone with any amount of VRAM that is nowhere near their limit be having it?

It's not a VRAM limit problem.

I do not have this problem on DX12 mode with my GTX 1660 Ti (only 8 GB).

I‘m the OP with a 4090 and I had it until I cleared my cache. I guess you didn’t read the first post. 

I did a lot of tests with my 1080ti 11Gb first, then with 3080ti 12Gb and finally with the current 4090.

test base Inibuilds EGLL gate 534 (facing east) Fenix A320, 4k and textures in ultra, from Cockpit view to outside view:

1080ti:

DX11 FPS 30, VRAM 10.5Gb, no ground texture artifact

DX12 FPS 25, VRAM 10.5Gb and ground texture artifact showed up

I then reduced textures to High and LOD to 100

DX11 FPS 35, VRAM 8Gb, no ground texture artifact

DX12 FPS 38, VRAM 8Gb, no ground texture artifact

 

3080ti:

DX11 FPS 38, VRAM 11.2Gb, no ground texture artifact

DX12 FPS 25, VRAM 11.2Gb and ground texture artifact showed up

I then reduced textures to High and LOD to 100

DX11 FPS 45, VRAM 8Gb, no ground texture artifact

DX12 FPS 44, VRAM 8Gb, no ground texture artifact

 

4090 (frame generation ON and LOD 300):

DX11 Not tested

DX12 FPS 70, VRAM 16.8Gb and no ground texture artifact

No need to reduce texture quality

It is clear that the artifacts showed up whenever the maximum Vram of the GPU was reached on DX12.

Anyway, I decided to move to 24GB GPU in order to avoid to ground texture bleeding and I am finally able to enjoy DX12 optimization and better CPU handle in MSFS.

Wrong - I've seen at Aerosoft EBBR while taxiing out a few weeks ago, never on arrival, though.

No I have seen texture issues with only 10GB used from the 24GB.
So nothing to do with reaching the max amount of VRAM

Except that it's happening to people with 24GB 4090's and to others including myself when their VRAM usage is nowhere near their limit. I'm not sure how many more times I need to say it.

If my Vram usage is sat at 10 and I have 16 and it is happening what can we conclude from that?

Do you have an Nvidia GPU?

it was happening to me until I jumped to 24GB

it didn't happen with DX12 under scenarios where VRAM were below the maximum.

As I said, I am not trying to convince anyone, just showed my own experience with test reaults and pictures...let anyone decide.

BTW, LatinVFR KMIA had a ground texture bleeding in terminal J which was a bug and was fixed in the last version but was there until 2 weeks ago.

No, buddy. My card is in my sig.

The first time I saw this the first thing I checked was what my card was doing and how much VRAM was being used and it was nowhere near the limit. It's never been near the limit when it happens. The fact that this is happening to some people with way more VRAM than the sim is using and not happening to people with small amounts of VRAM that the sim can easily eat up suggests that this is an issue which has little or nothing to do with reaching a physical limit and points to some other kind of problem. That problem could be any number of many things and I'm sure they will fix it eventually.

I wouldn't be at all surprised if they already know what it is.

Virtually same rig, absolutely the same result.

Same rig as well .. I live with it as DX 12 is too smooth to go back to dx 11 and it only happens at the departing airport on the apron (mostly). If it was happening to the textures while in flight or at the arrival airport i would have to switch back to DX 11.

I am patiently waiting for Asobo to get to the bottom of this and issue a fix.

Also .. please note this isn't a VRAM issue. My Vram has never even come close to being maxed out .. topping out at 14 gigs out of 16 in the bad old unoptimized days. and on top of that im on 1440p so texture size isn't blowing vram usage out the water.
