KFLL terrible performance in V5, LEMD unable to load

Hi,
I have just purchased the excellent KFLL/LEMD scenery. Visually nothing is wrong with them. However, the performance is horrible. I get 20fps max in the default jet at FLL. In V5 at LEMD I flat out can't load the simulator because my GPU runs out of memory. Surprising to me because I would get 30-40fps at LEMD in V4. I have followed the guide to performance in the manual, for both airports, disabled everything in the configurator. Still 20fps performance in KFLL and can't load into LEMD. Any help is appreciated.
No KMIA Scenery
Not using trueSKY
i5-6500 @3.2GHz
GTX 1660 Super 6GB VRAM
16GB RAM
Thanks

Hi, P3dv5 uses heavily Vram, and that's an issue Lockheed Martin is working in order to reduce these CTD's. I suggest in the mean time to reduce texture size to 1024x1024 in order for it to work whilst they fix it without having those issues. let me know

Hi, unfortunately reducing textures to 1024x1024 doesn't do anything for me.

Were you having these same issues with the P3dv4 version?

No I was not. In V4 at LEMD, I would be getting 30-40fps in the FSLabs A320, most likely even more with the default jet.

There are many performance issues with P3dv5 that Lockeed Martin is trying to resolve, I hope they release a hotfix soon for that, as you can see if it worked well in p3dv4 and not in p3dv5 its a p3dv5 issue.

Just want to add that the only LVFR airport I have installed into V5 so far is Miami and I can barely get it to load.
Once it does load the Vram almost instantly hits the limit and crashes.
I know that LM are working to fix some of the issues with Vram and V5 so far but Ricardo I'm sorry to say there is something it seems with your scenery that is worse than with other comparable scenery.
For instance I have installed:
FSDT: CYVR, KLAX, KDFW, KIAH, KMEM, KSDF, KCLT
Flightbeam: PHNL, KSFO, KPHX, KDEN, KMSP, SEQM, NZWN
FlyTampa: KLAS, CYYZ, KBOS, YSSY
Orbx: LOWI, ESSA, ESGG, LDDU, LYBE
WFSS: ZPPP
Most of them don't even hit 5GB Vram when first loaded from the select scenario screen.
None of them crash V5. The only Vram crash I have had with V5 so far has been at KMIA.
Flightbeam KSFO for example loads at 3.9 and never goes above 4.1
Even FT's KLAS which is an incredibly detailed, complex scenery plus the strip and city and with all detail options selected on loads up at 5.9 and sometimes nudges up to 6GB but doesn't increase.
Miami as soon as its loaded is at 6.5GB and in seconds it hits 6.7 when I move the view and Vram runs out (on my 8GB card) and P3D crashes.
So yes its absolutely true that V5 has some problems and that LM needs to do some work, its also true that KMIA (and it would appear from simple_es LEMD as well) consume far, far more Vram than other comparable complex addon airports.
Going to try my other LVFR scenery and see how they fare.

So I just installed the new Hotfix for V5. LEMD it will load now however I have to use very low settings. If I go too high, I still sometimes get the "your 2080 super has stopped working" message/crash.
With other airports such as Flytampa's Copenhagen this is not an issue.
So maybe my request is if it would be possible optimize this scenery more to make it better compatible with the resource intensive v5 version?
Cheers
Janis

Hi, with PBR textures, and truesky the VRAM on large complex airport is going to be high if you have texture size above 1024.
please use texture size 1024 while truesky is still in beta.

Hi Ricardo, I was also thinking if it is possible to have a “lite texture” option in your airports? reducing some of them from 4k to 1024?
I love your airports but I need to reduce my texture resolution and also some other sliders to keep them under 9.2gb which is my limit.
