The people trying to point out that this falls short of photorealism are missing the point. This is a tech demo aiming to show off the next generation leap unreal engine 5 is making. There’s lots to be impressed about here and this was made using a ton of procedural generation using a team of just about 70 people.<p>Here’s a great deep dive into some of the new technologies that highlights the strengths and weaknesses of some of the new engine tools: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;ib6_c6uliLg" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;ib6_c6uliLg</a><p>This is extremely exciting this is possible on a year old console and not a 3090.

This writeup is unsubtle in being a puff piece. The demoed tech is very impressive! Individual stills taken from the video are pretty convincing.<p>The motion version definitely still exhibits uncanny valley, though—lights that are too hard on flesh, tightness and sharpness where there should be softness. That I have to resort to hand-wavey descriptors is cool; they’re getting close! But crossing uncanny valley is HARD.<p>What this demo convinces me of is not that we’re there; we are not. Claiming that we are is disingenuous, and makes me distrust the claimant. But it makes apparent that we will get there. And that’s impressive.

Thanks to HN, I checked it out on my PS5 tonight. Very impressive. The thing that immediately jumped out at me was the 24fps target. The demo has a cinematic feeling, and thus the 24fps framerate feels “correct.” Compared to 60fps, you can do a lot more when you have 2.5x as much time per frame.<p>The first part is a CGI representation of Keanu and Carrie-Anne. I was shocked at the quality; it had “the demoscene feel,” if you know what I mean - “I did not know the hardware could do that.” Artists going full OCD, just because it was the right thing to do. Great work.<p>Parts of it had that CGI feeling, but most of the first two minutes, I swear I was watching video and not CG.<p>Part 2: the city tour. I am not sure if there’s a detailed YouTube video of same, but the artists used some clever tricks, as any good 3D artist would. You can fly around and peer into offices and apartments through their windows. There are a limited number of static rooms, and they use frosted glass to blur the details. Interiors are fully modeled and there is parallax through the glass. HVAC units on rooftops are robust, down to the warning messages. Great use of LOD.<p>I saw Z-fighting and LOD “popping” when surveying the city from on high.<p>I walked away from this (um, got up from the sofa) thinking Epic’s gambit is to push Unreal Engine 5 as a virtual movie set.<p>They went all out on the character models in the first part, with Keanu and Carrie-Anne. There were a few uncanny valley shots (“dead eyes”) but very impressive overall. Some of the shots could be taken as a reference, or gold standard.<p>Even more impressive is that it’s running on a (loss leader) $600 Sony PS5.

Meh, these guys are still stuck in the uncanny valley.<p>Objects are often absolutely beautiful and realistic, but interactions between objects are ridiculous. Some of this is probably just &quot;not enough processing power&quot;, but it is also due to where the rendering bumps up against the primitive controls. For example, you have a very realistic human. But then the human walks against an object, and she does this standard video game 0 mph duck-walk. Part of the problem here is that real humans don&#x27;t bash into walls. So how do you realistically represent that, when in fact it&#x27;s just Johnny pressing forward on his controller?

I&#x27;m surprised at the amount of comments with a jaded tone. This is one the most impressive tech demos I&#x27;ve seen running on real time, and I watched Second Reality by Future Crew back in the early 90s when it came out.<p>The car chase sequence is mind blowing and then you get to free roam the city by foot, car or even drone. Nanite and lumen are something special.

I think the demo could have been more effective if the non-realtime elements were indicated more clearly; as-is people got confused what was realtime and what was just pre-recorded. I suppose that was kinda the point, but without any sort of reveal the effect gets lost. I don&#x27;t know if the console demo had the option to switch to &quot;nanite view&quot; at any point, or just in the &quot;gameplay&quot; section, if it does then I guess that would help with the situation.

Ok, I was under the impression that the white room scenes were a mix of filmed and digital assets, not 100% renders. In this context it is very impressive. The later scenes are very good, but in as others put it still in that uncanny valley area. We are on the up-slope however!

&gt; The technical demo also puts previously showcased UE5 features Nanite and Lumen on display. After the interactive chase sequence, users can roam the dense, open-world city environment using UE5’s virtualized micro polygon geometry system which provides a massive seven thousand buildings made of thousands of modular pieces, 45,073 parked cars (of which 38,146 are drivable), over 260 km of roads, 512 km of the sidewalk, 1,248 intersections, 27,848 lamp posts, and 12,422 manholes in a virtual world that is slightly larger than the real downtown LA. Additionally, as one drives or walks around the city, you can pass 35,000 metahumans going about their everyday business.<p>That is some amazing tech! It actually feels like Unreal Engine would be really well suited for other genres of games, not just the historically prevalent FPSes, such as creating RTS games or maybe even something like Cities: Skylines, in which being able to create large detailed urban environments could be amazing!

Real time de-ageing + Zoom + remote job = less age discrimination. Have it randomize other characteristics during job interviews to remove other forms of discrimination too.

The faces especially Trinity looks underwhelming, comparing to real life. Like a big gap. I’ve seen better facial expressions I.e Last of Us 2 but with inferior graphics.

It’s notable that they mention the problems de-aging Keanu which really contrasts to the “Keanu is immortal” meme from a few years back. I guess age finally caught up to him.

Keanu looked insanely good at the beginning of the white room scene, but then I realized it was real footage when they switched to the uncanny-valley-esque version at 1:41…<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=WU0gvPcc3jQ" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=WU0gvPcc3jQ</a>

I sometimes think if an article like this got done with actual images of people while claiming it was CG, there would still be a lot of, &quot;I could tell immediately it was CG&quot;. &quot;It is so terrible&quot;, and &quot;The faces look so bad&quot; etc.

A better link might be the press release from Unreal themselves [1].<p>The Verge also did an interview with Keanu Reeves and Carrie-Anne Moss on the process of creating the demo which is quite interesting to watch, too [2].<p>[1] <a href="https:&#x2F;&#x2F;www.unrealengine.com&#x2F;en-US&#x2F;blog&#x2F;introducing-the-matrix-awakens-an-unreal-engine-5-experience" rel="nofollow">https:&#x2F;&#x2F;www.unrealengine.com&#x2F;en-US&#x2F;blog&#x2F;introducing-the-matr...</a><p>[2] <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=0OK80eljWrs" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=0OK80eljWrs</a>

It&#x27;s just a (playable) tech demo, alright. We&#x27;ll have to wait 7 to 10 years until we get games close to this anyway. Remember the &quot;Samaritan&quot; UE3 tech demo? That thing is 11 years old by now [1] and the closest we have to that is probably CP2077 ... and only if you ignore the console ports, yuck.<p>[1] I am aware of the fact that &quot;back in the day&quot; they used three 580s in SLI or something crazy to run it, but that performance was already surpassed two years later by single card setups.

I think what I would like to note is the appropriateness in Unreal demonstrating this with Matrix. An engine and an film from the same era (if I remember, the the first full release of the engine was the year before the film).<p>For the technology itself, it is incredibly impressive but more than anything and something which is hard to demonstrate with a demo, is how easy it is to actually use. Nanite models are simple to make from 3d objects, this with photogrammetry would be a dream.

Tech demo aside, the city model is remarkably detailed. When we went exploring different alleys and flying over buildings we couldn’t find a “forgotten” corner. Does anyone know what the asset for the city is from or will be used for? The thing is massive and seems to be bespoke art.

The most impressive thing is the scale of the city and amount of traffic. In other games you feel that buildings are way too small and every object is placed by hand for convenience to a player. This tech demo nailed the feeling of a livable metropolis.

I know there are companies using virtual models to showcase clothing. Is replacing actors and actresses next? In some ways I don’t mind it, and decentralizing away from celebrity culture may even be a societal good. But I feel like some experiences are better off organic. Is there any point to appreciating - as an example - ballet performed by a virtual dancer with unrealistic athleticism? Will sports matter? Should they? I am not sure how things will play out but I expect all these norms to be challenged in the next 50 years.

50 years separates that from this: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=fiShX2pTz9A" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=fiShX2pTz9A</a> Fifty years! Just Half a Century! It&#x27;s nothing, nada, niente, 0! compared to the scale of universe. The Idea of a simulation isn&#x27;t absurd if we take this progress in consideration.

This is super impressive and a huge leap toward photo realism. The draw distance and content streaming using nanite is nuts.<p>Next I want to see what kind of tech demo they can make run smoothly on a mobile device at 120Hz. I.e. does the tech scale downward too? Or is there no point to it unless you require extreme scale and fidelity.

I just watched YongYea on youtube showing the Tech Demo on PS5 and I was in awe. Being a PS user for a long time the graphics of this is amazing. I can&#x27;t wait till this kind of graphics hit the VR space. So much cool stuff is going to be happening in terms of games and how we perceived reality.

I wonder if one day there will be companies that will just sell iper realistic models of complete cities or popular zone to be used in games or other kind of applications.<p>Like companies such as Tele Atlas did back in the days for map data (when they didn&#x27;t have much more than that I guess).

Does anyone else kinda feel like videogames look good enough at this point? This demo looks fantastic, but I don&#x27;t think many visual improvements beyond it seem super exciting to me. I&#x27;ll take them when they come, of course, and I&#x27;m sure that realistic 3D worlds in videogames will continue to look better and better as time goes on.<p>But I dunno. I hope advances in videogame engines do more than just help the biggest AAA titles improve their photorealism.<p>What do we get as the technology improves beyond the point shown in this demo? Just better graphics, or a democratization of the production of photorealistic games? Does this somehow open the door for smaller teams to create games that involve photorealism, or for more budget and staffing resources in the development of photorealistic games to be directed toward other aspects of the game?
