High VRAM usage | P3D v5.3 HF2

[Meowsa]

Hello P3D community.

Lately I've been noticing more and more that my VRAM usage is peculiarly high.
During cruise with all addon aircraft (QW787, PMDGs, FSLabs) VRAM usually does not go below 6.7GB. With the default F-35 I usually hit 5GB just taking off from a default airport. At addon airports with addon aircraft I get OOM's.

I wasn't like that at all with 5.3HF1 or 5.2; and I doubt it's caused by a 3rd party addon since I haven't purchased a new one in over half a year.
I use a 1440p monitor but VRAM usage stays high even when I change the resolution to 1080p.

VRAM usage is apparently not linked to settings because even with "low" settings I still hover around the high VRAM area. Have tried deleting Prepar3D.cfg with no avail.

I have made no changes to my computer (hardware nor software)

I do not have those payware add-on aircraft, but some complex add-on scenery with 5.3 HF2. Overflying the most complex of these I "only" use up to 3.2 GB of VRAM out of the 3.6 GB available to me, so I would say this is caused by the aircraft.

Ditto Jorgen .... flying any PMDG aircraft with maximum display settings and ASP3D/ASCA I typically run 3-6 Gb on my 11 Gb 2080Ti. I've seen some scenery push it as high as 8 Gb.

Something is definitely wrong with your system or configuration. You should never see an OOM due to VRAM when using P3D and DX12 because DX12 allows the application to control VRAM instead of the OS as it was in earlier graphics API versions. Check top make sure you have the Windows option for hardware accelerated GPU scheduling enabled, but I would be surprised if that is your problem. Good luck finding it and please report the solution.

I completely agree, Dan. It might be an idea for people with these issues to check this out:

and, of course, also to check with the add-on developers.

Windows has changed your system with updates...

[JorgenSA]

Like I said in another thread, I have not noticed this, and I have not heard of others that have experienced this.

At least not in Windows 10, which I am going to continue to use for a while yet.

Do you have any information to support this?

I have witnessed this when I updated to hotfix 2... my vram in sim was only getting about 5-8g when I have a 1080Ti and it should have 10G of vram.. in fact on one flight, the allowed vram was changing constantly, which it should never do, only the usage should move...

When I reset my permissions, that was fixed.

[JorgenSA]

Allow me a quote: "the allowed vram was changing constantly"

If you mean to say used out of the allocated VRAM, then it will change during a flight, depending at least upon the complexity of the terrain you fly over, and probably also depending upon the complexity of the aircraft you fly.

The allocated VRAM should not change unless something is running in the background.

thats exactly what Im saying, the figure on the right (the allocated vram amount) on one install was constantly changing as if it were the figure on the left..(the current vram usage)

I reinstalled the sim and it didnt happen again.. Im guessing maybe some files did not have the access required as this happened before I sorted out my permissions.. now on the current build... I load into a flight and for a few seconds everything is fine (default sim) and then 3 seconds later, MANY textures go black for no reason...very strange. refreshing the scenery sometimes fixes this, sometimes doesnt.

I have exactly the same problem, super high VRAM usage.

PMDG 737 NGXu at a basic airport gets 6.9.

QW 787 at a basic airport gets 6.7.

Same exact settings on v 5.2 HF installed as v 5.3 HF 2.

Let's stop making excuses for LM; 5.2 HF was great, no problems at all whatsoever.

Obviously something is skewed, and just because 100% of the P3D users do not experience it, does not make it unreal or false. That logic is myopic.

It's 2022, let's get it much better please.

Agreed 100%. Many of us have several thousand dollars invested in software and hardware trying to enjoy a sim that continues to be problematic time and time again. I'm also tired of LM being so casual and cavalier about known issues with the sim and having us scrambling and frustrated trying to figure out what's causing the issue and how to resolve it or if it can be resolved without a hotfix. They do this to us with every new version and as long as we keep supporting this product the way it is they will continue to do it in version 6 and beyond. I have reached my limit with v5 and will not support further versions of P3D.

BINTL ,

Do you have High Vram usage?

No other pilots posting for the past two weeks in this topic.

Updated my p3d to the latest version and now I have the same issue.
Did you manage to somehow fix this?

Allocated Vram 8GB
flight loads up and used Vram is already 7.1, i change the view (still on runway, not moving or doing anything) and Vram jumps to 8 and OOM!

SOOOOO frustrating

Same problem here mate right after updating my P3D to the latest version.
Did you by any chance manage to find a solution to this?

Cheers mate
