Is it possible that in a forseeable future we can expect VrayNEXT GPU "out of core" architecture?

[PIXELBOX_SRO]

Hello guys,
i was wonderign if there is at least slight chance that Vray NEXT GPU get out of core architecture like Redshift has?
So that we can chew more memory hungry scenes while being able to utilize graphics cards?
Just thought i would as

Thanks for reply!

Vlado talked about out of core in Siggraph last Summer, they have been working on it for some time. Both out of core textures and out of core Geometry
We will probably see this tech in the upcoming update to Next but I'm not sure.
At the meantime, Vray is the only renderer that supports Nvlink and memory pooling with variety of cards, some of which are very affordable like the 2080/2080Ti
With 2x 2080Tis you can handle up to 130 million polys on GPU, which is insane. Nvlink works nicely in Vray Next and unlike out of core in Octane/Redshift/Cycles, it doesn't affect the rendering performance at all!
In my humble view I do think that out of core is overhyped and you would think twice before going out of core in a production environment. Even RS/Cycles documentation doesn't recommend going out of core unless you have no other option because it affects rendering speed. Let me know about your experience if you tested it in RS or Octane 4 or Cycles
It is a welcome addition to Vray and I don't know how it will affect performance, but like I said using it myself in RS, I do think that it is not usable in production, you should probably stick to whatever fits in your VRAM.
On the other hand, If I ever run out of VRAM on Vray, I swap to C++/CPU and DR
This is another advantage of Hybird rendering in Vray, so you can render your GPU scenes on your local CPU based render farm, even if your nodes don't have Nvidia GPUs..
Another point is that RS will use 90% of your VRAM no matter how big your scene is. Devs say it works this way to make RS as fast as possible, I tried manually setting the VRAM limit in settings and It never slowed down my renders
On the other hand, Vray GPU only uses a fraction of your VRAM depending on how big your scene is. Specially with IPR, Vray is very memory efficient and uses less VRAM compared to Octane,Cycles,RS..
so if you are running other instances of Max or you have other apps that is using VRAM, you don't need to go manually and change anything in settings.
