P3Dv5 Excessive vRam usage

How on earth would this issue not come up in Beta testing? It's a serious question and I would be interested in your opinion. Not a slam to LM dev's.

There was a new beta build just 8 hours before release..

None of my video cards on my tests PCs have CTD with the settings I run the sim at. Neither other beta testers.

Everyone here with the problem is not indicating:

What settings they use. What video drivers they use, what card they have, etc, etc.

The combination of variables are unlimited.

Please provide data to LM..

You are more than welcome to ask to join the next beta and when this situations occur in the future I will ask you the same question. Let's see how you feel and respond.

I just noted when I turned my setting from unlimited to 30FPS, my video card relaxed and all was good.

Well this has become a tricky situation. Clearly using the extra Vram has played a part in better performance, but now scaling it all back in order to mitigate Vram OOMs will degrade the visuals we now have with the new airports and all the PBR in aircraft and airports. Be grateful LM is willing to work for a solution for our crowd, otherwise, the alternative  since P3D is marketed to a corporate commercialised crowd, is to swallow the pill and invest in very expensive hardware that has a whole lot of Vram. Surely there will be a solution that provides a balance between the two, but we saw this coming. People demand better visuals, better features, but they will most certainly use more Vram, more powerful GPUs, CPUs down the road.  Dont be surprised that 12gb Vram will be mainstream in due time.  After all  we said 4gb of ram was plenty years ago, then 8gb became mainstream, and the cycle repeated. Now in a year or two 32gb of ram will be common place.

It seems clearly related to TRUESKY. Which to be fair is considered a feature in Beta.

 

When I turn it off I gain 1.2 Gigs of memory, depending on the situation.

The odd thing though is that the amount of cloud coverage does not seem to influence much. Having it active even in clear sky has a noticable VRAM impact.

Agree

When disable true sky no problem over EGLL and London City altough as allready mentionend in 4K still i only have 400 - 500 MB left. Which is not enough for a FSL A320 i guess 🙂

 

-- Update: 

Restarted P3D -> Same Settings only Enabled True Sky with Medium Cloud Resolution and Locked FPS internaly at 60 FPS and i could do the same flight over London City but had a ussage of max 9 GB Ram so very close to OOM. 

But before i had the oom directly after takeoff now i could fly over the whole city without issues

Well we should be thankful that they have a return policy at all. With digital products you usually don't get those.

Flight1 provides a 30D refund for I believe most all of their vended software.

Having just built a new PC strong enough to run P3D well enough I decided on March 7th to purchase v4.5.  I used v3.4 on the old build for the past 4y, and v2.x before that.  I paid $199 for v2.x, $199 for v3.x, and now $199 for v.5.  I had heard v5 was coming along but didn't know how imminent, recalled their history of 60d refunds and besides didn't want to install 3.4 on the new build.  Well, a few days ago I learn about v5 releasing April 14.  So I contact LM and asked if they would kindly extend the refund offer, or at least discount v5 for me having bought v4.5 all of FIVE WEEKS AGO:  Here is there reply:

Hello,

If you have purchased Prepar3D within 14 days, per the refund policy, you can request a refund and then purchase the desired license of Prepar3D v5. There are no exchanges, upgrades, or discounts available.

Regards,
The Prepar3D Team

Yeah, regards.  Wretched policy for a loyal customer who never scammed them w/ the academic license.   I know I'll be happy to continue w/ v4.5, it's very good w/ all of the wonderful add-ons we know and love and I use it a lot.  I'm looking forward to MSFS2020 and will be more than pleased to lose the charade EULA 'not intended for entertainment purposes'.

Also an exception to the rule.

I´m quite happy now. 

I know if i want to fly with FSL or PMDG i disable True Sky which is in Beta and all is good. 

I fly now my fourth circle over London city (all sliders full right) also could raise SSAA to 4x from 2x and no oom nothing and i have 33 - 35  FPS with locked frames, no Autogen Popping everything crisp and nice. 

With 4.5 even with the default aircraft i hardly reached 11 FPS with not everything fully right. So i´m happy for now.  Hope to see PMDG and FSL soon then all is nice.

 

FlyTampa, Flightbeam , LatinVFR and ORBX are allready there 🙂

From Virtuali at FSDT,  "Be CAREFUL with your settings, because P3D V5 consumes a lot of VRAM. A video card with 8GB is strongly suggested. Better if you have more...the sim now has an indication of your spare VRAM memory, so you'll know when you are going too high".  I take this to mean anyone with a midrange system or lower will have a lot of difficulty unless they drop their settings to the minimum, or close to it.  With my 4GB card, I know I don't have a chance until I upgrade.

That's what I needed to hear.  Cannot build new system until at least after this pandemic, and really wish to wait until MSFS 2020 specs are out in the open.  Having trouble with my aging FSX setup now, so really in a bind.  System specs appear below.

I am noticing performance improvements over P3D v4 for sure. I'm running in 4K, with pretty high settings (not fully maxed out). And I'm getting GPU Memory 5/6.7GB and Frames are hovering between 30-50fps. This is on a vanilla install of P3D btw. The only add-ons I currently have running is Chaseplane. I'm going to wait for the third party developers to release official P3D v5 installers before I can get a real taste of what my actual fps will be with all add-ons. I'm hoping for the best. So far so good though.

[jabloomf1230 2,445]

Has anybody experimented with this setting in V5?

UseGlobalTerrainView=True

The default is False. It makes a blurry mess of things in P3d4 if you constantly change views, but as I recall it does reduce VRAM usage in V4. I assume that TrueSky is probably a VRAM hog also.

[mikeymike 360]

Ok now it’s getting confusing reading some of the comments where by most are running high settings and are almost running out of vram and some are not.

on a 2080ti or 1080ti 11gb

If you don't fly 4k you will be fine! The issue is happening to users on 4k with high SSAA settings all P3D settings Maxed!

All I have is a 4k 50in tv for a monitor. No way I'm dumbing down my hardware for a P3D upgrade version. Nope. Now I normally run x8 MSAA on my 1080Ti but I see others still having issues. IMO, this v5, in it's current state, is a failure.
