News Nvidia neural rendering deep dive — Full details on DLSS 4, Reflex 2, mega geometry, and more

[Admin]

Nvidia provided in-depth details on the various neural rendering techniques that will be unveiled with the RTX 50-series later this month. Here's everything you'll need to know about DLSS 4, Multi Frame Generation, Reflex 2, DLSS Transformers, and more.

I’m part of that 80% of gamers who use DLSS; at this point even the well optimised games need DLSS for my 3080 to hit 60 fps at 4K so I’m thankful for the tech. Now if the new DLSS is available for older gen graphics cards and can help performance even more then I am all for it.

With NV everything is great until the next gen is here.
Then, everything was sh!t and now it’s great.

I wish they would provide more details on what features will make it into older cards. as well as detail what changes they made with the 9th gen NVENC.

If the neural textures can save on VRAM, they need to bring it at least to the RTX 4000 series so that their 12GB cards will last a bit longer. and prevent the 4070 from running into its own RTX 3070 situation where it became one of the shortest lived cards due to the lack of VRAM.

There is a table of what makes it to the older cards as far as DLSS goes. The VRAM improvement will work with Series 40. And all other improvements, aside from MFG will work on all Nvidia GPUs starting Series 20.

Actually, the table they showed doesn't clearly indicate where "neural rendering" features land. What it shows is where the DLSS upgrades are coming. So 50-series has MFG, 40-series has single frame generation, and everything else gets the ray reconstruction and transformers upgrades.

I also want a table like that, only for neural rendering features. All we have right now is this:

So, we have Neural Textures, Neural Materials, Neural Volumes, Neural Radiance Fields, and Neural Radiance Cache... are these software features, or hardware? I think on some it's a bit of both. The tensor cores and shaders in Blackwell have been upgrade to support better integration of tensor operations (i.e. the "neural" stuff) within shaders, but it still sounded like all of the same operations are possible for other RTX cards as well, they'll just be slower at it.

Neural Textures, Neural Materials, Neural Volumes, Neural Radiance Fields, and Neural Radiance Cache

There won't be a single game with support for this in the next 2-3 years. And it's unknown whether they will appear at all

Possibly, or more likely Nvidia will partner with some companies to push this tech into the wild. And there's also a new API from Microsoft that's supposed to help support some of this stuff (again, unclear if that's "coming soon" or still a ways out), which would provide a theoretically vendor agnostic standard that would work with AMD and Intel GPUs.

Given the potential improvement in image quality that could come via NTC at the very least, I suspect we could see some real effort to get that used in games in the near term. Slashing VRAM use by 2/3 isn't something to scoff at, even if it ends up requiring a 50-series GPU. For that matter, using NTC to get higher quality textures into games would arguably be more beneficial than the continued push for ray tracing.

Of course, if it's Nvidia doing the pushing, what we'll end up with is a game that has full RT along with these neural features. Just because.
