Scarily photorealistic

PS: Wow, just look at that apartment, would love to live in one like that

Can do this in Unity as well. It just won't be optimized. It will do fine for an escape room title, or a point and click adventure, but not for an fps or a game with really large areas, such as an MMO.

Frostbite, Gamebryo, idTech5, MT Framework, RAGE, 4A Engine, Anvil, Dunia Engine 2, Fox Engine

UE looks really impressive. I just want it very optimized.

Cryengine has been one of the best out there. I remember playing Crysis 2 and oh man, the visuals were way more stunning than anything I had ever seen in a game.

Crysis 1 and Warhead were better than C2.

Gameplaywise, but Graphicswise Crysis 2 was better. I wish it was in an open jungle like environment though.

We can only know that once some games are released for it.

This demo won't really be optimized for mainstream hardware either.

C3 >> C2 >> C1 (graphics wise)

C2 got better than previous games visual vise after they got that HD Texture update.

Unity 5.0 - voted most user friendly engine according to developers and #5 best tech invention (2014)

That would explain why suddenly there are so many 3D mobile games.

Seeing all these Tech Demos I feel like all game engines have reached stagnancy. All of them look good but there is little that really separates one from the other in terms of graphics. Also all of them are pretty much at the peak of optimization in order to render all such scenes.

I think the real next step would be to create a truly voxel based engine or a fully raytracing engine.

Here is an example of a Voxel based engine:

And here is an example of a Raytracing engine:

Both of these are still experimental since there is no optimized way to render graphics using voxels or by raytracing in real time.

- - - Updated - - -

In case you are wondering what a Voxel is, a voxel is a volumentric pixel. Therefore, its a pixel in a truly three dimensional space unlike current graphics where the scenes are rendered two dimensionally using techniques such as z-buffering which gives an illusion of depth. The limitations of using voxels is that the number of voxels required to render complex scenes can become extremely huge and rendering such a scene would require tremendous amounts of memory.

Raytracing is a technique of tracing the path of a light ray in reverse (i.e. from the eye to the object we are looking at), simulating its effects such as reflection and refraction with objects and rendering the scene using that data. Therefore it has the potential to render extremely photorealistic scenes.

Yup voxels based engines are really making their presence known. Till now, people thought that voxel means blocky, which is no longer the case.

And Nvidia's gameworks tech tends to be used in multiple engines
so these are already being used, from Cryengine to Evolution

But realism alone does not make a good game, we could do with good AI or great gameplay

I don't think there will be a fully voxel based engine anytime soon, at least not for another 5-6 years. They are simply not optimized enough to run on mainstream hardware.

- - - Updated - - -

I am really more interested in Raytracing engines but those are even more nascent than voxel engines.

In case you are wondering, here is what Raytracing can do:

*hof.povray.org/images/bigthumb/glasses.jpg

More examples: POV-Ray Hall of Fame

Those are still images however, and creating animated scenes is still far off.

However, someone did create Raytraced Quake 3 sometime back. Let me see if I can find the video for that.

- - - Updated - - -

Got it:

procedural generation is another option, it only means longer load times, but the memory footprint is very low
like 200-300 MB can be converted to a 96KB game if it is procedurally generated
.kkrieger is a demo of this, if you don't want to download you can just look at it here, but the gfx scales according to the machine

Yeah, I played .Kkrieger. Back in the day it had pretty high system requirements considering its small sub-100KB or so filesize.

However, they haven't released the next episodes after this one.

"A bad workman blames his tools"

A good workman, however, creates masterpieces with what he's got.

Game engines are just middleware. How good a game looks actually depends more on the level design and art development than the game engine.

Engines only provide a set of tools. They may help in ease of implementing those tools but in the end it depends on developers on how well they utilize them. I feel that with the current generation, most of the top engines are more or less in the same page in terms of technical capabilities.

A classic example is how the last generation of games were created. We can all agree that Cryengine or Frostbyte or idTech5 may have had more "better looking" visuals than Unreal Engine but look at the number of games other than the flagship titles that implemented them.

UE on the other hand spawned not only games but entire franchises with varying levels of graphical fidelity and gameplay. I'm talking about Bioshock, Mass Effect, Borderlands and many more. These games used "a heavily modified" unreal engine and not just plain vanilla unreal engine. Which brings me to my "good workman" argument.

tl;dr :- no engine is better than the other in terms of graphics, it all depends on game developers

^wanted to post something similar. The pre-release game-play videos always look great, but the finished project is never up to the expectations the devs themselves have set.
Realism could have actually killed good design.

Digital Extreme went on to use Evolution instead of Unreal in their latest project, and it came out well

Makes sense.

However, the purpose of Tech Demos is to demonstrate cutting edge technologies. Whether developers use those tools or not is another matter.

An early Vulkan API tech demo running on Android

For those of you who don't know, Vulkan is a new graphics API that is a successor to OpenGL and a competitor to Direct3D 12. Unlike Direct3D 12 however, Vulkan can run on all mobile devices, PC, Mac, Linux, Windows and even older windows versions such as XP and 7. It is essentially Mantle 2.0.

if im not mistaken, Vulkan is a fork from Mantle itself that both Nvidia and AMD will support, thats very good news for the green army !

anyways

No, Vulkan is a fork of OpenGL. Vulkab is also managed by Khronos group, the same group that manages OpenGL.

The new CryEngine 3 tech demo shows photorealistic textures :

CryEngine 5 announce video with some gameplay demos.

Through this we play games with what? A PC right.
Since I don't know where to post it
I posted it here
I think this piece of software is a brilliant idea to integrate all other launchers into 1 place and keep tabs on them.

But this is not that much of a cutting edge technology. A tech-demo is a demonstration of some new technology in graphics or other such computing, see the other posts above for examples.

Yeah! this is Gaming Engine thread as mentioned in OP.

@Desmond David : Perhaps, you should change the title as per context.

new Modern Warfare is a new benchmark in graphics quality with respect to requirements.
Frostbite may now have a contender..

Hmm, Battlefield 5 vs COD MW

Battlefield 5 also uses ray-tracing AFAIK.

^^Yup, it was the first title to advertise ray-tracing in FPS game

Now, how this dev revamped the Tomb Raider 2 (1997) using Unreal Engine 4 is so mesmerizing

And the official teaser for Crysis remastered

Sent from my Nokia 6.1 Plus using Tapatalk

Remaster of a tech demo, more like. XD

IMO Crysis wasn't that good of a game. It's graphics were it's real selling point. Also it's graphics aren't that bad even by today's standards, so I wonder what would be the advantage of a remaster, other than ray tracing perhaps.

Sent from my GM1911 using Tapatalk

Crysis is a good game. There is no other game where I felt like being the Predator. But the remaster is pointless especially when it's coming to Switch. They should make a new Crysis game with at-least one year exclusive to PC.

The most fun segments of crysis were against human enemies.

Rip my GPU. It was nice knowing you

It's just a tech demo for now. I don't think devs will just throw away normal maps. It will be good for indies though.

Time to get RTX2080Ti

I have been thinking of getting 2080 super once this lockdown ends. It's expensive AF though, so perhaps down payment is the only way to go.

Not really a demo but looks amazing nonetheless :

You've probably delayed it enough for next gen GPU to be out soon. I'd wait for that.

Nanite is awesome...
here is the complete Developer review of UE5

Looks like the UE5 demo.

Apparently Sony has some deal with Epic, that's why they don't mention UE5 and PC in the same sentence.

, it is improved , tho it doesn't wows

Even I will upgrade once covid crisis is over, looking at 3070 now.

Umm.............. Lets just hope we don't wait for a long time.

Will target for 3080 or 3070 now. Just waiting for other OEMs like Zotac to start manufacturing. Will check their costs and then will decide.

Do you really want the aftermarket cooling solution though? The founder's edition looks sic! No other design is better than that imo.

There is no warranty for founders edition cards. For nvidia, asus and zotac are best options in india

No hope for any quality after sales support in India unless you know someone.(just like most other things) In case of gigabyte too it is probably because of their rep eddie on /r/indiangaming that their online reviews are good because those who had bad offline experience would probably never met eddie & never posted negative online reviews.

For a moment I thought it was shot in GoPro camera

Wow. Though you can see the graininess of the raytracing in some places.

Exactly. The Rain effects is so realistic. The water effects on Wipers movement is so awesome.
And I was surprised when I saw this game was released in 2014 on PS4.
PS5 has pumped up the graphics a lot

I will buy this exclusive game for sure if I get my hands on PS5.

Any one who has been waiting for this?

Insane amount of detailing by Nanite

Another real life graphics in Racing

Any good presentations from mobile game devs?
I remember vainglory and shadow fight 3 talked about their development process?

Any of y'all tried this? It's a free playable tech demo of Unreal Engine 5.

Got Goosebumps!! Damn Amazing for Tomb Raider Fans

Imagining the Witcher 4 in Unreal Engine 5.

Raytracing with reshade is usually only screen space. It's not full fledged ray tracing so usually it doesn't work as well in indoor scenes, but outdoors it's usually not noticeable.

This game was released on Switch and still with Cemu and RTX4090 they made it look like PC port with Breathtaking visuals.

MetaHuman is Amazing

Wow Senua IRL

Zangetsu said:

Wow. That actually looks pretty good.

Seems like the basic premise is to generate face rigs on the fly.

Yes, and the Unreal 5.2 demo of Lords of the Fallen is pretty awesome too.

When I heard we can travel two worlds in this game, immediately I get reminded of Soul Reaver. Perhaps finally we have a worthy successor, a soulsborne clone too. cant wait!

Unrecord photorealistic gameplay

That is some God level graphics. I thought someone was trolling that it's a game when I watched this first time. But that was on phone.
I just watched on my 1080p 27" monitor, and I still feel someone is trolling that it's in game graphics.

Graphics are indeed quite good though I think reloading & shooting pistol will give it away to those experienced with arms in US.

Modders did what nvidia doesn't want to?

SaiyanGoku said:

Yeah, was expected. I hope Nvidia is forced to make DLSS easily accessible like how they were forced to with gsync.

Which CGI engine is this one ? Damn looks so real. The movies made on it will be Block Buster

Seems AI generated.

Yeah. AI has taken over reality. Hard to find out real or fake

Internet is already getting flooded with ai content, Everything fabricated.

I suspect because the characters move very little and do simple movements across what looks like few seconds worth of frames. Tell tale sign of AI generated video.
