I always find it a tad disappointing when render engine demos only use inanimate matter objects rather than organic stuff. I guess because Sub surface scatter and skin texture (bump, displacement, normal map stuff) is far more expensive to render and equally as difficult to make look real, than something made of plastic rock and metal. It's still nice to see more and more lifelike looking stuff become realtime for games. Great vid by the way. B)

If you want to learn more Carmack gave a talk at QuakeCon a few years back about how computer graphics are generated. And IIRC he also talks about how you do it "properly", ie with ray tracing and BRDF materials (Bidirection Reflection Distribution Function). Basically it's a way to define all possible light interactions when a ray hits a surface in one function, or if your prefer "it makes shit look real". kzread.info/dash/bejne/gmqJrcqLYLeck9Y.html

this is the first real attempt to bring 3d animation algorithms that we're used to see in the movies, into real time hardware. This is pure gold.

This is awesome - Thanks for your more detailed videos such as this that delve into information about things that matter!

While his information about refractions, while on the surface, isnt technically wrong. There is a reason why none of the demos have anything with refractive properties. at minimum a refraction is going to require 4x the trace depth to achieve similar quality results to reflective materials. the problem is that 4x trace depth isn't 4X more processing its more in the realm of 4 orders of magnitude higher in processing requirements, because of the nature of ray tracing. this is why we wont see ray traced refractions in games for a while, but will have hybrid render engines that create raytraced AOV's such as ambient occlusion, reflections, shadows etc, that are composited over a more traditionally rendered real time frame.

I would have thought refractive materials would cost only 1 extra path (the path from the surface going inside the object to the surface were the ray leaves the object), and this path is somewhat faster since the ray only needs to search for an exit-surface for that object and not the entire scene. Although that assumes none of your objects are overlapping.

UHD Gaming PC, I’m sure Intel was saying the same thing before Ryzen release but if you follow the technology then you would know Vega was not the one set out to be the game changer, Navi was. Vega was just the stepping stone until they could properly utilise infinity fabric into their GPUs, making Navi a true scalable GPU. It’s already making waves in the CPU market and combined with 7nm architecture. We have no idea how much Volta GPU are going to set you back but all expectations put it at more that the current equivalent. If the use of infinite fabric allows for better yields per silicone and the miners stop or least reduce their obsession with AMD cards then we could be looking at a competitive future. Remember consoles outsell high end GPUs it’s already looking like that Sony at least is going with Navi architecture so expect games to be better optimised towards AMD than Nvidia come 2019/2020 because Vulcan optimised games already have shown in some benchmarks Vega64 beating out the 1080. I would not get your hopes up on an 1180ti/2080ti (whatever they decide) this year. They will draw out Volta same as Pascal so expect it 2019. I’m an Nvidia fan but I’m not going to fan boy them by dissing on AMD. Nvidia only has two considered consumer friendly cards better than the 64 and they too showed that with high demand prices rocketed. We should all be wishing AMD well because true competition, competitive prices and innovation will be the reward for every gamer.

The main thing Nvidia did was make a denoiser based on deep learning. With that (and some other tricks) they can generate a good image with just a single sample per pixel. For decent performance that requires their tensor cores though, because they use those in their deep learning algorithms. The tech is really built around their own, newest GPUs. Tom is really a great guy, honestly. I just don't like the ethics of the company he works at and as the employee of that company he may have to do things I disagree with. Among which RTX is one of them. Nvidia effectively writes part of the rendering pipeline of a game, whose performance on both GPU vendor's hardware will influence potential GPU buyer's decisions. IMO game devs should not use code they themselves can't read or both the vendors. If AMD and Nvidia are both like "yeah, it's good code" by all means. If one claims to be at a mayor disadvantage because of the way it's coded, or simply not have an idea, then there's something wrong. If you let AMD paint your house, you get a red house. If you let Nvidia paint your house, you get a green one. But in de end both would be better off if you just painted it white yourself.

A cool thing about many raytracing software is that the image quality and render time is highly based on the number of rays the camera emits, so I believe it wouldn't be too difficult to increase fps by decreasing the number of rays emitted on the engine. Of course, you would sacrifice quality over fps, but how much is probably going to depend on how good that denoise filter is.

hey Steve, Im a game developer which uses Unreal Engine in which that Star Wars short-movie sample was made. One of the developers which worked with that demo told us he was using a GTX 1070 with half screen resolution for that scene and getting 8-10 FPS during most of the development of the scene, meaning that the technology can work on lower end hardware, but it is not optimized. Depending on how you assemble a game, it is very possible to see this tech in games sooner than expected, but will required optimal hardware to perform well

And this half screen resolution was A * Y pixels? The demo video from unreal only seems to offer 1080p, which is 1920x1080 pixels. "Half screen resolution" can be a bit ambiguous and can mean either 1920x1080 / 2 or 540p, which is 960x540 pixels that takes a quarter of the time. Also did he mention if FP16 was used for the raytracing when using V100s (which have double throughput)?

@NilsonFeLima

6 жыл бұрын

Half resolution is a term we use in game development to reduce by half the amount of pixels being handled internally on the GPU, meaning that even showing an image of 1920x1080 it will really affect only half of pixels which reduces the quality in order to increase performance only. This is useful during development so you wont suffer dealing with slow frame rate which is terrible for creative work (the editor has its own workload on the GPU to consider). There are two videos from GDC to get the details from the implementation with Unreal + ILM + nVidia colaborators: kzread.info/dash/bejne/fHV_utuMicmyh9I.html and this one from the nVidia's CEO kzread.info/dash/bejne/a2mi0sqvpLnMY5c.html. Also Im asking about to real rendered resolution (I think it was 4K) and also about the FP being in use.

Tom is a great addition to the channel!

Nice interview! I really enjoyed listening to that guy. Would buy him beers and ask a million questions!

Super interesting, thanks very much!

Tom Peterson is always great to watch and listen to.

It's nice to have what all the food fight in the food court explained. I have several questions. Do games have to be specifically optimized to benefit from ray tracing. If so how do you know which? Is MSFS2020 one of them? I know that it already struggles with FPS and it is difficult to run with even high end hardware with all the features turned on high. Is ray tracking worth an additional hit? Same applies for other games. Is it even worth talking about for the near future or are we at least a couple of generations away from it?

Great interview.

Thanks for the video! Enjoyed watching this and it gave me a great understanding of the basics. Ray tracing looks gorgeous, but the power needed to determine every angle of light contacting the camera at 60FPS must be absolutely bonkers. I wonder if standalone physics cards will make a comeback to do those calculations and let the GPU focus on the graphics. It would also allow the consumer to choose how much ray tracing they wanted by buying a high or low end card. Not sure if that's even feasible. But I like the idea.

great stuff, best content is usually if some field expert gives interview.

Great video! You deserve more subs!

Great introduction. Just to add a detail destinction: the holy grail is actually Monte Carlo path tracing. Basic Raytracing can be done in real-time since ten years, path tracing is the hard one. Nvidia Intel and AMD all have developed fast libraries over the years, the new thing with RTX is just the integration into the driver so that it can be used like an extension. The performance will still be similar, you just won't have to waste your time on writing and optimizing compute shades that much anymore.

Using xbox series x should I download raytracing packs just using a 1920×1080 will it try and compensate for that or would it not work on a normal TV, as I noticed on forza it seemed to work even know I didn't think it would

I missed something at the end. When he talks about getting Ray Tracing into the public, is there something/someone blocking this, or is he referring to tech companies catching up?

It's can be a pretty hard thing for hardware to do. It's how shadows are rendered, try shadows off then on and check your load and fps. I've worked with real time simulations and adding ray tracing is easily the most taxing of all things I've done.

this is my favorite GN video so far. while this video might have felt 'easy' to make by comparison, it's all your technical hard work which put you face to face with this opportunity, and prepared you with the right questions. well done GN, and thanks Tom for being willing to chat. respect.

GN i think it would work well to use a add on card full of tenser cores to simulate the light and tne normal card for the rest

Hmm wonder if a wider Fov would dramatically increase the amount of tracing that needs to be done.

Fabian Tschopp True, even the rather rudimentary filter in the Q2 raytraced project does a fantastic job with cleaning the image. I thought it was still fairly impressive with how clean the image was after the filter. Then again, we have no idea how efficient it is. Most everything will run fast when you have over 240 tflops of performance. This whole demo does seen rather overblown though. Two or three bounce raytracing using the rasterized environment as an HDRI background is not nearly as technically advanced as they lead on. Otoy has been showing this level of tech off at SIGGRAPH for years, they just didn't use a supercomputer for the demo.

Yeah and the filters don't even have to be used on the whole output image (as opposed to full-scene raytracing). Since only ambient occlusion, reflexions and maybe sub-surface scattering will be done with RTX first... this basically means you do: 1. Generate textures/shader input data based on raytracing 2. Filter textures/shader data based on convolutional filters 3. Apply to objects...

8:47 No amount of Volta will be able to trace the rays bouncing from your hair.

I really like listening to Tom Petersen, seems like a genuine nice guy.

When playing games, I never compromise on my reflection setting. It really adds something special to the scene.

I'm guessing that Ray Tracing will come with a big performance hit, even on the RTX cards. It might be really hard to run it, especially at higher resolutions, so once it's available, people might not be enabling the feature all that often, or perhaps they just won't be able to run it on its highest setting. It has to start somewhere. The same sort of thing has happened with other cool looking graphics techniques as well. Maxing out AA used to be something which wasn't worth doing, but over time, they found more efficient ways of doing it, and the cards also simply became more and more powerful.

9:52 the most relevant question!! There is no point if hardware can handle this amazing/stunning/awesome feature if devs don't even know how to work with. It's like give a Space center for a kid.

to think that, still, this is only the beginning of real time raytracing progressing, and it looks so good now, i cant wait to see what the future holds

This is a really good explanation for ray tracing.

I'd love to see that demo generated with only way tracing, but fully, to compare a real brute force render (like they do for movies today) with the real time nvidia is doing on volta, and see the differences.

I’ve been waiting for re traced lighting since vxgi was announced

@Gamers Nexus Wish you'd asked about whether or not RTX increased complexity/cost of content creation; I imagine raytraceable scenes require more/different material information than even today's complex rasterized scenes contain. The short term hybrid lighting systems Tom suggested again sound like they'd increase the complexity of content creation; assets needing to be either segregated ahead of time, or be compatible with both rendering pipelines. On a related note, is RTX something that would be realistically retrofittable to games already in production? (e.g. Star Citizen)

I hope this gets widespread adoption in games and isn't left to rot as some rarely used proprietary nvidia bullshit.

Good news!

If anyone watched the release of the pascals gpu, when they showed the server which rendered an image - there was a person on stage with the host who gave nvidia a challenge, next time his on the stage he would like to see that done on a single gpu, I guess nvidia took the statement srsly and making the following advancements

Kind of funny to watch this interview after RTX was released.
