P3Dv5 Excessive vRam usage

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

I'm running W10 PRO. My Task Manager shows me with 11.0 available for my 1080ti 11GB card, but in P3D V5 the upper left corner readout shows me 9.6 GB available...something's up.

Shows for me, too.

I am sure they are. We'll look forward to their updates!

Nothing is suspicious about the "discrepancy". We don't really know what LM means by "available VRAM". All we do know is that Win 10 itself can use anywhere from 500 MB to 1 GB of VRAM with no apps running, so it makes sense that with an 11 GB card, one will not be able to use all the VRAM for an app.

Can you do the same screenshot without P3D running?

I took a shot of my Task Manager after a fresh boot and then after loading in the AS A330 at FB KSFO.

Where did you read that?

In my primary forum, flightforum.ch. The guy tested now a 8GB card, there he gets 7.1GB instead of 6.6. A small step, but at least in the right direction.

This is why I don't jump right in to a new program.  Looks like I'm staying with v4.5. Cheers S. Sumner

Just that little bit would make a big difference for me. No matter what I do xxx/6.6 is the max for my MSI RTX2080 Gaming Trio.

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.

 

 

No I'm not saying that the task manager is lying 🙂 but probably it shows you what windows is using, not what it has reserved for program x

Win 10 1909 reserves 20% of the available VRAM for the OS. Win 10 2004 which is being rolled out gradually and is available to those in the Windows Insider program appears to use less. An 11GB GPU shows 10.1 GB available and an 8GB GPU shows 7.1 GB available, so it looks like the new Win 10 version reserves 900 MB VRAM, but that needs to be confirmed by users with >11GB and <8GB VRAM.

As others said...that's normal with Win10 1909 and an 11GB card...at least from what I've experienced with my 1080ti 11GB card.

Another data point anyway.

I didn't know that there was a new build of Win10 on the way.  I'm thinking if it reduces OS use of vram that's good -- but they haven't seen some of the wallpaper I have :)  -- talk about vram use.  heh.

I've noticed the DXGI_DEVICE_HUNG crash in P3Dv5, which I do not think is the same thing as vram starvation (?), but maybe it is.  DEVICE_HUNG might be the same crash we saw with the TDFi 717 in v4, it sure looks similar.  When I had the DEVICE_HUNG crash my vram was well below the limit.

It not only reduces the OS's VRAM usage but it seems to do it more sensibly. Rather than reserving a fixed percentage of your GPU's VRAM, it now reserves a fixed amount. This benefits cards with large amounts of VRAM, but whether this impacts cards with less VRAM in the same manner still needs to be confirmed.

youd think by 30 pages people might get the idea. I'm amazed LM didn't pick up the issue in testing.

I have a GTX 970 4gb, at the moment with 1024 textures I get about 2.8GB our of 3.4 available with standard scenery and airplane. Hope that after the hot fix that LM will release i am going to be able to play the game. Don’t have the money for a 1070 or something
