I have a RTX 2080 and not even medium settings all over. I run on 2.560 x 1.440 Pixel with MSAAx 4 and locked on 30 fps with 2k textures, as well as a scanlinesync/2 to bring it on half of my 60hz that the monitor does, 

So you are running at 2K instead of 1080P (HD).

There is something very interesting on your screenshot as your video card is showing only 6.6GB of VRAM available.. I gather your video card states it has 8GB? if this is the case it means your Operating system is taking 1.4GB just during boot operation which is a bit excessive do you use multi screens? This would contribute to use almost 2GB just for the OS.

Since your PC is consuming so much VRAM just to boot, I would suggest Instead of reducing the sliders all the way to the left to change your textures to 1K (you screen already displays at 2K so your would not notice big difference) this should save you at least 1 to 2 GB of VRAM and give you some legroom.

Isn't that totally normal? My 11Gb 1080Ti shows 9.2Gb available inside v5, this is almost exactly the same ratio as 6.6Gb for a 8Gb Card (83% of the VRAM available).

Interesting you say that; this has been part of this whole discussion. The way VRAM is now managed we effectively have less. I have 8GB VRAM and my OS uses almost none of it. As you can see in this shot, P3D is only giving me access to and protecting 6.5GB of my VRAM, despite the fact that the rest of my system is only using 400M(4.9GB total used), so there's 1GB more that I used to have access to in DX11. I guess(?) this is a DX12 limitation, but it is part of the reason I have to use lower settings in v5 than v4.5.

Are you able to access more of your VRAM somehow on your installation of P3D5? Would be great to know if there's a way to give P3D more of my VRAM.  When I put the 16GB Radeon VII in to test yesterday, P3D only showed 13GB of VRAM available, so it had partitioned off 3GB of VRAM for the OS.

Sadly thats not the case. I wish it would be like that.

I have a RTX 2080 and not even medium settings all over. I run on 2.560 x 1.440 Pixel with MSAAx 4 and locked on 30 fps with 2k textures, as well as a scanlinesync/2 to bring it on half of my 60hz that the monitor does, 

Here you go

 

Yes, its only some of the sceneries i get this problem, mostly the ones already named, beeing LatinVFR newer stuff like KFLL and KMIA. BUT, and that is a big but there....this is in the dash 8 and even standard planes, without a single addon installed. Even if other airports give me 4GB usage only, what happens when GSX and PMDG comes out? Or UTLive? I bet then every halfwy modern airport with v4.5 features (PBR etc) will bring us to the max with a real plane like B747 or QW 787.

Then i can set my sliders to minimum and fly in FSX visuals. And that on a 3k Euro PC.... extra build for flightsim a year ago.

I dont see what LM could here either, its a drectX limit and the addon developers have to handle it. LM is  already trying do something right now and that is that first a popup should appear where it gives a warning that the GPU is nearly maxed, giving you the possibility to hit "retry" which lowers the settings to minimum. Sadly this doest work at all and the sim still crashes. Even if it would work, who wants to fly in minimum settings for the rest of the flight?

THe problem why the device hang appears even with this implementation is that it seems that the popup can detect the nearly crash 1 frame too late. And this is what they want to fix (comment from Beau Hollis). That the popup with the warning appears correctly and not directly throws a gpu hang. 

I love P3d through and through and would not change the sim easily but i see some real problems coming to us and developers with v5. 

 

PS: ignore the unlimited fps in that pic.... the same happens with the mentioned 30 fps lock, no difference.

I have the same card and have come to the same conclusion , add Vr in to the mix which is an added gig of vram with a spike of 1.6 on single pass and I am lost to the answer hopefully LM can create some magic but apart from a rescue box not ideal not sure what they can do.

It seems for P3D dedicated GPU Memory is what matters. 

Mine is showing 0.4/6GB usage prior to launch P3D. And P3D is correctly telling me I have 5.6 available inside the simulator:

Can you check this:

* Reboot (so all is fresh)

* Check your available VRAM prior to P3D

* Then check inside P3D.

Hello,

I am trying to understand this. Apparently, the Task Manager is quite happy that I have 8 GB available and I can see that

P3D v5 is using 4.7 GB and the system is using 0.5 GB, a total of 5.2 GB and leaving 2.8 GB free,

What I am not understanding yet is that P3D is reporting a 6.7 GB maximum, leaving only 2 GB free.

Can you do the same screenshot without P3D running?

Certainly, here you are:

Perfect.. now this is puzzling and I will report it to LM devs.. doesn't make sense.. maybe it is related to the bug of CTD..

S.

maybe p3d is calculating different then windows.

 

I have 16 GB but p3d also shows me "only" 13.6 GB.  

I have  2 monitors :

1x 32 inch 4 k resolution 

1x23 inch full HD 

p3d runs only on the 4k screen the small one shows the desktop.

It seems that the newest Windows 10 version, version 2004, enables 10.1GB on a 1080Ti. Can somebody verify this?

Where did you read that?

 - when is a beta a true beta? When you turn on TrueSky!

I dont think its a bug but how directx and windows handle vram. You have given the answer already with your post, windows reserves the rest. LM is aware of that and says its right behaviour that an 8GB card shows ~1gb + less

Edited April 20, 20206 yr by Senchai

Looking at task manager, Windows reserves 0.5 GB, or are you/they saying that Task Manager is misreporting as well?

Either way, running out of 6.7 GB at conservative settings is not really acceptable.
