1. Submissions have to be related to games

Video games, tabletop, or otherwise. Posts not related to games will be deleted.

This community is focused on games, of all kinds. Any news item or discussion should be related to gaming in some way.

2. No bigotry or harassment, be civil

No bigotry, hardline stance. Try not to get too heated when entering into a discussion or debate.

We are here to talk and discuss about one of our passions, not fight or be exposed to hate. Posts or responses that are hateful will be deleted to keep the atmosphere good. If repeatedly violated, not only will the comment be deleted but a ban will be handed out as well. We judge each case individually.

3. No excessive self-promotion

Try to keep it to 10% self-promotion / 90% other stuff in your post history.

This is to prevent people from posting for the sole purpose of promoting their own website or social media account.

4. Stay on-topic; no memes, funny videos, giveaways, reposts, or low-effort posts

This community is mostly for discussion and news. Remember to search for the thing you're submitting before posting to see if it's already been posted.

We want to keep the quality of posts high. Therefore, memes, funny videos, low-effort posts and reposts are not allowed. We prohibit giveaways because we cannot be sure that the person holding the giveaway will actually do what they promise.

NVIDIA confirms DLSS 5 uses a 2D frame plus motion vectors as input (videocardz.com)

NVIDIA had earlier described DLSS 5 in a way that suggested a deeper understanding of the scene. The follow-up answers paint a narrower picture. When asked whether the model reads PBR (Physically Based Rendering) properties from the engine, NVIDIA said: “DLSS 5 only takes the rendered frame and: “DLSS 5 only takes the rendered frame and motion vectors as inputs. Materials are inferred from the rendered frame.” In other words, the model is not reading metallic, roughness, normal maps, or other underlying material properties directly.

That may explain why some preview images raised concerns. In one example, a character appears to gain hair detail in an area where it was not visible before. In another, facial details appear altered enough (like the nose) to raise questions about whether the model is changing the look of the character rather than only improving lighting. NVIDIA’s response was that “the underlying geometry is unchanged,”

Slow down there Kenobi. It may technically not change the underlying geometry, but that’s because It ignores it. You never see it.

Technically correct is normally the best kind of correct but here we are...

This was intuitive and obvious to anyone paying attention to AI and who knows video game engines. Nvidia trying to imply anything else is really shitty.

Calculating each mesh or surface in the scene instead of one big collective pass would be even more demanding. And will likely be beyond their capabilities for a very long time.

So from fake frames to fake ray tracing with a AI Only Fans filter.

Plus, yeah that nose

For leaving the underlying geometry alone, that nostril grew twice times its size.

[–] HarkMahlberg@kbin.earth 16 points 4 hours ago

Oh my god I see what happened - DLSS thought the SHADOW of the nose was actually part of the nose. That's hysterical.

You are forgetting the €5000 graphic card you'll need to access these coveted features.

[–] NekoKoneko@lemmy.world 3 points 2 hours ago

I think we're being too quick to judgment on this. We're forgetting that this is a vital step in Jensen Huang's plan to make $1 trillion from selling AI accelerators to new data centers, which I think we can agree is what really matters to most gamers.

So is not so different from an Instagram filter, huh

[–] MyTurtleSwimsUpsideDown@fedia.io 3 points 2 hours ago

It’s a really fast instagram filter.

[–] inclementimmigrant@lemmy.world 2 points 3 hours ago

It sure doesn't seem like it.

Daniel Owen's interview with the Nvidia's Jacob Freeman which is where the analysis of this article is even more illuminating:
