It weakens it for GI, but doing per-triangle tests for GI when you can only afford a few rays per pixel was never the best use of it. Reflections are still good.

We all know that - but compare the first thing people saw running on Series X and the first thing people saw running on PS5. This was a really really good move by Sony, marketing wise. Next round, 1st party titles from both sides. Exciting times!
Why so much fanboy crap and less excitement about the technology. This technology is beneficial to all. Be happy even if the demo wasnt on your platform of choice. It gives us a good idea of what we should expect from true next gen games over the next couple years.
How is the PS5 powerful enough to render 25 billion of tris in real time, (and that's just tris alone, with GI, 8k textures and everything else?) Surely it's not THAT much more powerful than last gen?! Right now the budget on a AAA PS4 game is like what, 20 mil?
This is some wizardry.

With what I saw in that emo, RT can go to hell for all I care.
But the good news is that tech like lumen means that RT can be used sparingly for things that any raster-based lighting model doesn't account for do well. Eg, reflections.
For those complaining that Assassin's creed is still going to be 30 fps - This demo was 1440 and 30 fps on the playstation 5 and there was no ray tracing
This is a bonkers brute force of this kind of detail and i wonder what it would look like for something targeting 60 fps

The first thing people saw running on a Series X was either Halo Infinite last year or Senua II. Both looked amazing.
I've been a huge fan with everything Microsoft has been doing with Xbox Series X but this was a smart move to show something this awesome running on a PS5. Really hope Microsoft shows off something awesome running on an Xbox Series X because last week's third party showcase was rather meh to me.
This is why the talk about diminishing returns makes me laugh, while this looks insanely better than the PS3, This looks like ass compared to all Sony 1st party games on PS4, let alone great 3rd party games by mid gen. I wouldn't be surprised if we get the same this gen by 2-3 years in.The PS4 demo for comparison
Unreal Engine 4: Real-Time PS4 Tech Demo
Epic Games shows off a new tech demo for Unreal Engine 4 running in real-time on PS4.youtu.be
It is a marketing tool that is only focused on rendering and doesn't have any of the systems games have to worry about running underneath of it. People should be skeptical until we see a game that will actually release.
I am assuming the original model is billions of triangles and UE5 is dynamically doing LOD.
True, but to be honest that really just means downgrades, but in this case, i think it's more they went overkill with the amount of tri's, i can't see any game doing that next gen, you can half the number of tri's & achieve similar results, then use those resources for something more important.
UE4 Elemental Demo for Playstation 4 | Unreal Engine
At the PlayStation Meeting 2013, Epic Games showed its new Unreal Engine 4 "Elemental" demo, the first public real-time demonstration for PlayStation 4!Want ...

Don't forget, this was the equivalent last gen (only it wasn't controllable unlike this new demo)
they said they intended to be playable at gdc, so the spec reveal was affected by covid.... we got just the specs without a demo.
Re: John's comments at 11:05, I'm actually wondering if he (or I) misunderstood. Because I'm under the impression that part of what they described for UE5 is that the mesh adjustments that let them run "movie quality" models in real-time can automatically scale them to platform. Like, the engine "understands" geometry well enough to cull intelligently. John was saying that running this demo on another (lower-end) platform would require manual LOD creation, but I thought the point was that while the detail obviously wouldn't look like this, a title engineered for UE5 wouldn't need traditional re-authoring for assets.
Ironically, Anthem is a concept that would have come much closer to realization with high speed SSDs.
The GPU increase is only like 2.5X from mid gen refresh. The real magic is from use of PCIe SSD and this new engine that allows devs to dump highest detail Z Brush models without making lower LOD versions, saving dev time.
From what i understood, the engine renders only what you see, and polygons per pixels, so it doesn't render the billions of polygons.
over 6x the cpu.
Over 8x the GPU (vs XB1)
Over 6x the memory bandwidth (vs XB1)
Over 100x the IO throughput.
Yes, it's THAT more powerful.
The best thing coming from all this is hopefully lightening up the workload for developers and allowing them not to make near as many compromises to their artistic vision they have for a project.
I'm sure they will have something amazing to show. It's just been interesting lol, to see Microsoft do quite well with XSX so far but fumble their "gameplay reveal." And Sony fumbled their hardware "reveal" but did a great thing by making this their "gameplay reveal."
I wonder how much geometry you could get away with that doesn't use any kind of texture mapping, just storing the data per vertex instead.
I know it would seem like I'm picking sides here (I'm really not, I'm getting both consoles) - but those were cutscenes, this was gameplay. I guess DF agrees with this judging by the "now this is next gen!" in their title: this is the first true glimpse of the next gen visuals, and both consoles will have it, but Sony scored marketing-wise by showing it on PS5 first - and that's a fact. Ball's in MS' court now, and I'm excited to see how they respond.
This was a smart move on Sony's part because now most people will associate UE5 with PS5 rather than the other platforms it supports.
This was a pretty smart marketing move.

Quote from the article :
"Hardware accelerated ray tracing will be supported in Unreal Engine 5, for example, but it's not a part of the PS5 tech demo revealed today. We'll have more soon on this remarkable piece of technology"
Interesting.
The Witcher III was a vertical slice running on NASA PC.
Xbox Inside had "in engine footage representative of expected xbox series X visual quality" => which means PC.
This, is a vertical slice running on PS5 dev kit. That's really, really not the same thing.

Which is strange when you consider how many teams on XGS vs PSS actually use UE5.
I am now excited. I'm just imagining some RPGs looking like that... better yet Knack 3 will look like a pixar movie
People like to say that you pick sides when you criticize a console. I have been called a troll for saying certain things and I have owned all consoles every generation for years.
I think you are right though. To the average gamer, this is ahead of what MS has shown. 1440p 30fps is meh to me, but not to the majority of people. I am more excited because the graphical technology advancements can proceed once again.
Yes, you're right, this was gameplay and it looked incredible. Can't wait to see what's next!
If Lumen is really that dynamic, easy to implement and has a much lower performance impact compared to RT GI, then I can't see RT GI being used a lot in the future, even on high end PCs, atleast in UE5 games. Maybe RT is used more to complement the new raster methods and used much more sparingly rather than replacing the raster effects.
I'm totally mind-blown... Honestly, it's shocking to see this unfold in front of your eyes... I keep frantically visiting every threads on the subject just being mindblown.
This would definitely have helped for context next to Cerny's Road to PS5 presentation. This seems to be basically the 'real' equivalent of the 'pac-man' graphics he used to talk about streaming gobs of in-camera assets on demand.
Better late than never I guess!
This was definitely what I'd consider gameplay. It's actually surprisingly representative of a real game (input, character locomotion, real time physics, etc.)
What NASA PC? Witcher 3 demo's were shown before even the GTX 980 was out, it just got downgraded because the XB1 is a shit baseline honestly that CDPR didn't have enough time to work around like say R* can, DDR3 for VRAM cmon. Thank god it won't be for much longer.
This was one of the bigger takeaways I got. Every generation there's this concern about budgets getting too big and games taking forever to make so it's good to see some effort being put on cutting down developer time as much a possible. SSDs, ray tracing, and engine advancements like they talked about in UE5 will be huge.
