P3Dv5 Excessive vRam usage

Recommended Posts

Add a little PBR and EA (if LM ever makes it worth using), and 8GB is suddenly obsolete. 

EA would make 0.6Gb difference (but is not in use) and PBR is running at present. So no major problems that can't be handled.


Intel i7 6700K @4.3. 32gb Gskill 3200 RAM. Z170x Gigabyte m/b. 28" LG HD monitor. Win 10 Home. 500g Samsung 960 as Windows home. 1 Gb Mushkin SSD for P3D. GTX 1080 8gb.

Someone mentioned on this thread I believe, that their may be some improvement in a coming windows update (21H1) to the handling of vRam. I upgraded today to that version on my sim, and I have noticed an improvement. I was able to raise my LOD from High to Ultra, and select "use high texture terrain" and not have my sim crash due to vRam overload. This test was done at an heavy piece of scenery, KMEM from FSDreanTeam in heavy weather. So I do think something may have been done in Win10 as suggested by the member.

It would be nice if others who upgrade to this new version of windows report their findings, confirming or not my observations.

Thanks,

Michael.

Watching this for sure… New windows and new P3D V5.2 

Curious to know how LM helped out the vram usage.

LM has optimized the VRAM usage quite a lot. This was one of the major topics for them to improve. And they have decreased  the overall usage and stabilized it also more (when flying and changing things).

I can highly recommend 5.2 over 5.1.

I concur. I just upgraded to 5.2, and where I had all my settings set below the P3D default, I now have them all at their MAX and the GPU load is only 38%, the CPU is also lower. Great job LM.

I’m on a 2080 Super 8GB as it seemed the best option budget wise during the time I was getting my PC, I’ve kicked myself every day since for not going with the 2080TI-hoping this will be a done deal now.

One thing I have found was that using 8xMSSA over 8xSSSA reduced the load on my GPU by approx. 50%. I also found that EA did not produce the clouds and their development that good; I found turning it OFF produced better and more realistic clouds.

I now have nearly everything maxed out except for the Autogen Buildings which remains at normal, and all this on a GTX1080 with an i7/6700 and 16Gb of Ram. I must say LM did a great job with this update - 5.2.

Seriously? That's insanely good...

VRAM management is much better, but it's not a total panacea. I still can't use the NGXu at LVFR's FLL + MIA without having to drag settings down or turn off EA to prevent a DXGI on a 8GB card.

why do you want to have two airports active at the same time within 30nm? I have both but disable the one I am not flying from/in.

I am on the way from EDDV to ESSA with the PMDG 737 NGXu. In VR (Rift-S), VRAM never exceeds 2.7GB. Frames are around 30fps and smooth. I am flying not very high (FL340). I see some slight wafer clouds, but only temporarily when the sky is re-arranged following a weather update by ActiveSky. I am glad to have updated to v5.2!
