![[4K] Nvidia RTX DLSS Analysis: AI Tech Boosts Performance by 40% - But What About Image Quality?](http://i.ytimg.com/vi/MMbgvXde-YA/mqdefault.jpg)
is Alex ray-traced or naturally blurry?
Aahhahahaahhaah thats just hilarious.
@UHD Gaming PC he looks like 900p to be honest
@UHD Gaming PC they need to lock 30fps I assume
A combination of Z-buffer positioning bug and DoF being set way too high!
Undersampling 85%
Something that I see nobody talk about is how all of these Ray Tracing demos use hard/solid materials. If you ever worked with a true full Ray Tracing renderer (Like Blender's Cycles) you know that those kind of materials are the fastest to render. Having a perfectly clear piece of glass renders relatively fast. But as soon as you crank up the Roughness slider the render times already noticeably increase as now single rays have to be split up as they pass through the glass into multiple to correctly light the surrounding areas. While these demos did show some rougher surfaces they didn't look correct. In the BF5 demo it seems to me like they simply blurred the reflection without properly simulating the surface being rougher. Water also should be a clearer reflection to begin with. Which to me tells me they use a relatively low amount of rays and then blur the results. I'm also assuming that the ray tracing treats ambient occlusion and shadows with all materials as hard/solid as well.
And even if we could render those things at 60fps with the proper amounts of rays then we still have to deal with large amounts of transparancy (like with leaves of trees) and the absolute render time killer: Subsurface Scattering.
No, we are far of from even doing the things shown in the demos even remotely accurate. They are better, yes. But nowhere near full realism.
Nice to see all you guys together. Been watching you since 2013! Thanks for your hard work.
as someone who does 3D rendering quite offten - hardware raytracing looks really appealng to me(as fast as Autodesk supports it). But as a gamer - I think it is somewhat of a gimmic,
because it is somewhat of a waste of GPU space...
On one hand, the prices are beyond belief, a 2070 shouldn't cost that much and it's sad that I waited this long with a 970. On the other hand, once you know 2080 Ti's die size, it makes sense as well.
Yeah with the Founders Edition 2070 at $599, I shudder at the cost of the partner cards probably being around $650, which I am not a fan of since I go with them because they usually overclock better and throttle less than the base Nvidia cards. I really hope AMD comes out with some cheaper but comparable competition, I never go with AMD since Nvidia always has more stable performance for a slightly higher cost but this time it's ridiculously higher.
I would prefer to see this with performance benchmarks and how it does when games that support Ray Tracing are fully released because I've seen this thing before where devs hype up a new technology and it ends up being underdelivered in the final product.
Alex is improving. It’s becoming a little easier to understand him, he’s enunciating more. Keep up the good work.
4:05
This is where Nvidia dramatically failed.
Ray Tracing is great, but if these chips are only 10% faster than the 1000 series then competitive gamers are going to be livid.
0:11 you said GTX twice instead of RTX
Its really great to see you on camera Alex!
"Get our new high-end cards for $1000+ so you too can play a triple-A game with a barely noticeable visual upgrade while playing at 1080p, maybe 60Hz...."
And it'll sell like hotcakes to the masses.
This is the weirdest timeline, ever.
Alex! Finally! Freundliche Grüssen mate :-)
Maschinenzimmer777 hehe danke Dir! Schöne Grüße zurück!
Dictator93 as a nickname fits you pretty well too eheh. Wunderschön! Subbed to your channel btw, good stuff in there ;-)
Loving the pc focused content can’t wait to see what pc gaming will be like after these cards drop. Consoles are suffering rn especially the upcoming ps5 and new Xbox since amd doesn’t really do much to innovate in the gpu department. In the years to come we will see a even bigger gap between pc gaming and consoles. So excited the future looks so bright.
It'll be like the 90s/early 2000s again as console likely won't support these features on a hardware level for at least 7-8 years.
Yeah, I think I'm gonna stick with my Xbox One X. The PS5 and Xbox 2 won't be even twice the power of the One X... Lots of games can still push 2160p or checkerboarded 1800p to 2160p @60fps. So the next gen consoles will be totally useless with AMD cards. Unless they gonna switch to Nvidia cards and get the rtx 2070, then it's worth it
Excellent video guys. You’re getting so good at these.
Hey! Is ALEX! Welcome officially to DF! Presentations are all done now!
Did you activated TXAA on Alex, what a shame.
I wanted to see the next leap towards 4K 144FPS G-Sync gaming... if i wanted to play at 1080p with unstable 60fps i'd buy an Xbox.
Yes the tech is "cool", but it is not something the market wants or needs right now ...at that price i'm reminded of the launch of the HTC Vive and Oculus Rift, new tech that is a hard sale + way too high prices for it to become mainstream anytime soon = low sales and little reason for Developers to create games for it, might as well wait for the version after that when the kindergarten problems are solved.
Waiting for real benchmarks like everybody else now ... not hyped anymore.
Cool to hear your explanations and thoughts on it. Keep up the good work guys :)
Crap, I forgot to disable depth-of-field on UA-cam again. Sorry Alex.
This is really interesting. I remember in ‘08 the first transformers movie so much of the realism was credited to ray tracing and how groundbreaking it was for the time. Crazy in 10 years it’s on now a $1200 card, and probably in our phones in a little more than half that time.
Burnouts And Bourbon yeah there was a time where you had to wait HOURS to ray trace something. Now you can do it in real time, it’s crazy.
I doubt we'll see it in phones, unless they have the hardware space of 90s phones
Robert Carter I think we will. I mean heck, 10 years ago the iPhone didn’t exist and now we have ps3 graphics on them. I’d say in 7 they’ll have advanced far enough to put this tech on em. I dunno, might be wrong...
Guys, I am trying, but I just cant get so excited abt ray tracing. I mean its a great feature but its still only shadow/light in graphics. What about the rest like textures, animations, resolution etc?
Those will see a bump as well as the rasterization portion of these chips is faster than their predecessors.
Honestly things like textures, animations and resolution have evolved massively. If you look at where we've gotten the last couple of years. It's really impressive.
As for shadows and lighting... well that has stayed the same for many years now. So seeing a potentially huge improvement there, is to me more exciting than another incremental increase in textures for example. Sure that's also nice but we've seen that way more often than we've seen actual improvements in lighting and shadows.
Also if I was a dev, I would be seriousy interested in this. Instead of having to use baked in lights and shadows (which have to be manually placed), you could just let the GPU do the shadows. reflections, etc. in real-time when adding a light source to an environment. Which would save a lot more time and on top of that would be a lot more accurate.
I was screeming of joy, I can see behind me in a racing game when I look at a side/mine mirror.
Great to hear your first impressions on this stuff. Can't wait for embargos to end.
well the big question is does it kill your framerate like all the nvidia options do. dont get me wrong they look amazing, but they pretty much destroy your framerate
It does.
even previous shadow settings are highly taxing on fps so you can be sure that raytracing will tank your fps like nothing else
Comparing nVidia software-driven options to nVidia dedicated hardware options is pretty silly. There also the fact this includes a huge jump in memory bandwidth to compensate.
Literally ONE GAME with the effect added at the last minute showed a hit in the frame rate, its like the others did not exist according to most of the comments!
i'm just going by experience with nvidia graphical option. they have always been framerate killers only one i have seen work decently is the nvidia hairwork. unless these cards run like 25-30% better then last gen it way to much to ask 1300 dollars for the new rtx feature. but i guess we have to wait and see when the cards come out and people tested them.
$1800 for the Ti? No thanks.
What I love about this channel is it feels like you're having developers and engineers explain techniques and technology to the masses
the diffuse reflections on the jacket are *spot on*!
Waiting for AMD to release a GPU that could do something similar.
AMD has it already for years now.
Really? You meant the RadeonPro with Vulkan?
Multi-plats mostly won't support it (I honestly hope they don't) because well PC ports in general are not that good and having to cater to these proprietary tech would probably on the whole make games worse.
Having said that big budget games or PC exclusives will surely make use of this
I can see developers actually using the RTX as a guide for creating their "baked" lighting model. Therefore the developer could potentially save time in creating the baked counterpart. Like this scene: 13:53
23:28 so hardcore PRO when John looks at the camera and shake his head when confirming someones statement😂 ...its like the ultimate Digitalfoundry's seal of quality😆, hell yeah🤘😎
those reflections on BFV it's everywhere on infamous second son running in ps4... so why we tax a big amount of $$$ for a high quality of the same effect, in other news nvidia officially said gtx 1080 vs rtx 2080 1:1 the increase in performance varies from x1.2 to x1.5 times then which is the generational increment from generation before pascal, because maxwell to pascal was about x1.5 to x2 times increment, ok no problem pascal was a big success piece of gpu then why we have to pay rtx 2080 the price of a gtx1080ti instead the $499 msrp of the pascal gtx1080... nvidia is playing bad this generation 3 years waiting it's not worthy and I believe anyone would prefer to play 4K with few tweek details to achieve 60fps because a gtx970 is able to do it with little compromise otherwise get a xbox one x, nvidia is becoming a luxury brand, btw 7nm is coming next year so we will see new nvidia gpus as well amd so close I'm really more excited for efficiency than raw power because at this point power raw is lame and expensive
It's a totally different effect.
Ray Tracing has been around since before DirectX was even a thing, and was always considering a holy grail as far as real time graphics goes. If this takes off, it will be huge.
holy grail is make the water look like real water
0:12 RTX, not GTX lol
Nice catch
You guys always do exceptional work, thank you! 👌
Previously, we wanted to know can it run CRYSIS. now we wanna know can it outrun CRYSIS? I want super FPS performance, not RT tracked optical realism. Rendering is heading to the North for sure but you cannot just buy a stunning, glossy candy bar without any taste in it. Something tells that things are a bit awkward right now.
It's not like hairworks, but it's more like Physix. In a couple generations it will be widely available, so no need to spend a premium on these new RTX cards
PhysX*
it actually IS just hairworks 2.0 right now. the 2080ti was struggling to render THREE lights in a 1080p scene, with a clear drop in performance for very little visual gain. so yeah. hairworks.
but not in the future. this was an important first step, but one that consumers shouldn't take right now. this gen is absolute garbage as consumer products. the worst since the gtx 5xx series
ON ONE GAME, that we know had RTX added really quickly at the last minute!
When has ANY new feature been added to a game and ran perfectly straight away? The drivers won't be final, the game patch isn't final. Optimisation is literally the last thing that is done on a game and the patch won't even be ready for launch day. So it seems pretty obvious they know there is a lot more optimisation to do. If it doesn't work well on the 2070 there would literally be no point in releasing the card!
The problem with something like this is that until they can implement in a way where it is fully used across the board, and it's noticably better looking than without it, people won't care. They should wait till we won't have to zoom in to see it. If you upgrade it slowly, it loses it's impact. It would come out with a bang.
They zoom in because its demonstration you have no control over so you don't necessarily have time to notice everything its doing. In a game you are playing, I'm pretty sure its far more obvious. Heck, half the graphical effects we use now its hard to tell what they are doing when switching them on and off. Its only the combination of them all together when you start to think "well this looks crap".
GTX is such an iconic name that even you said GTX 20XX instead of RTX 20XX in the start of the video :D
Nvidia shouldn't have renamed the high-end to RTX, people who care about Ray Tracing probably know that 2070+ will support it.
It'll be great in 2-3 years....doesn't pay to be an early adapter. $1200 card can't keep a solid 60fps @1080p with RT on.....that's all I need to know.
Can't argue with that.
If you still depend on 60fps your should get a G-Sync monitor first. 50fps gives you the same feeling. And you know nothing about the performance of finished products.
Watch Nvidia suprise launch a GTX 11 series without the tensor or RT cores about 3 months after everyone blows their money on this new tech.
Can’t wait for Bioshock 1 to be remote in RT. That room raider indoor demo was reminiscent
What lens did you use to shoot this ? It seems it has a crazy aperture !
too little, too early, too expensive, with time devs will implement amazing stuff with waaaay less resources, look at resi 2 remake, the game look stunning and is built on 2011/2010 based ps4/xbox one ( not release date, tech date)
agreed, i didn't say it's not the holy grail of lighting, it's a huge leap and an achievement in gfx technology to do that in this day and age (without AI core denoising, ray tracing would come in 2028) but it's still early since it's still so demanding even with AI denoising+ devs build their games on consoles.....i believe we'll see this tech fly off after in like 3-4 yrs only on PC, im not sure ps5 or xb2 can have that, maybe ps5 pro and xb2 X hypothetically speaking....
People need to stop trying to label the 2080ti as the replacement for the 1080ti. The 2080ti is the replacement for the Titan X according to the specs and where they fall into place with the 10 series. Although, Nvidia screwed themselves for any mid-cycle update to the 2070 and 2080. From the looks of it, if ray tracing isn't a selling point for you, then the 1080ti is probably the card to upgrade to for people running 1070's or slower. If you couldn't afford a Titan card when those released, then you aren't going to be able to afford the 2080ti. People need to stop doing yearly or bi-yearly upgrades to their hardware and also worrying about Keepin Up With The Joneses.
No it's a replacement for the 1080ti, no matter the specs or price, if it was a titan replacement they should have called it a titan.
Hey, so my understanding is that the AI is a crucial part of the ray tracing process as it is used to denoise the low density ray tracing. PS. Yous should have included Richard more!
I think someone missed the normalizing and/or leveling of the audio here. You all have different and dynamic ranges and the audio on this video is very peak-y and cracking. Also, you all speak at different levels. All I hear is the crackly echoing off my walls. Besides that, thank you for a clear and concise video on the RTX and standing by your integrity and asking to see the numbers and the end result of the product before fawning over the new cards.
Well what I've taken away from the RTX demos is that the surface textures clearly still don't have a high enough resolution to transport it byond that uncanny valley.
The materials all looked fake with RTX enabled. The lack of structural diversity in microstructures of the materials was off-putting, no material had any sort of depth, they were ONLY reflective surfaces! The was no light penetration in the depth of the water puddle, in the glass of the tram, in paint finish of the car.
The materials are clearly not up for the task, also I think the density of 10 Gigarays is not even close enough to imitate something like global illumination the sun is providing.
I would like to have seen how good the raytracing solution is with diffusion of dust on top on an object... that would have brought me some reassurance in Nvidias RTX approach.
All fair points, but is it better than what we currently have? I'd argue a big YES!
Buy as many cards as you want.
I'm just not in the mentality of an early adopter xD
And certainly not for 600 bucks
Still got my 980ti from 2015, got no reason or want to upgrade to the new 20 series.
You only really need to upgrade every three generations of GPUs or so.
What about the Lg 5k Ultrawide monitor? Or 1440p 120hz 3D monitors
I only have 1080p screens. That applies to a lot of us.
The cooler makes it look like a VHS cassette. Perhaps this symbolises obsolescence.
We need raytracing so badly. I can remember hype about raytracing as far back as 2005, good to finally see a working implementation. Does anyone else remember that article from around 2007 about the raytraced version of Enemy Territory Quake Wars that required several high end PCs networked together to run it? Now we get that on one card with way more complex scenes.
John Chronic still years away
@@cheappyv5156 apparently not as far away as we all thought back then
Looks pretty. Seems unnecessary. I totally see it as Hairworks 2.0
Patrick Like all their GameWorks technology, it is proprietary and there will be open source Ray Tracing tech in the future. It's not like PhysX is the only way to simulate physics.
Yes, is a BullsHit
Patrick 11:40 Like Richard said, right there. Devs are well versed in creatively faking it. Sure, Ray Tracing is super pretty, but I don't think it is necessary and I'm not happy about a proprietary implementation.
its not proprietary, its using microsofts directx for ray tracing
0x Neffarion Did Nvidia not say on stage how they have created some package of tech to distribute out to devs that can be dropped into their games? That sounds like proprietary tech to me.
what ye think of the tomb raider at 1080p cant hold 60fps? i was going to get a rtx 2080ti but that is a joke i have a feeling its only a 1080ti with tensor cores stuck on.
Give them time to finish developing the software. All new tech is rough in the beginning. It is incredible that some developers have even started implementing this in games already, the cards have not even been released yet!
No its only laggy because of the rtx crap. Turn it off and its a 4k 60fps card. Should be between 1080ti and titan v judging by cuda cores
Of course its laggy because of RTX, they have been developing the game for current-gen cards for how long exactly? Now how much time did they spend adding RTX? Is the implementation final (nope its months away), are the drivers?
Why the heck are people basing game performance on something clearly labeled as Alpha anyway?
The G-Sync point is an interesting one.
Could the performance hit of Ray Tracing be offset by locking the game at say, 45 FPS on a G-Sync monitor?
It's potentially a way to maintain smooth frame pacing while getting the visual benefits of the new technology.
Of course, this only increases the cost of an already expensive setup, but it could be a decent option for early adopters who want to squeeze everything out of their new card.
As always great work and great content.
meh
muh meh
It's not. And I believe DF would agree that it should be the performance.
Ray Tracing has been around since before DirectX was even a thing, and was always considering a holy grail as far as real time graphics goes. If this takes off, it will be huge.
great review guys! =)
It reminds me of the time geforce 3 was presented. It was slower then the most powerfull builds of older gpu but it brought the shaders tecnology to the table and it changed everything. In time every other model became obslete because vídeo game producers embrassed shading technology and the gpu had to have those instructions to even run the game like doom 3 for example.
The performance hit is not worth it.
Boom
You literally don't know what the performance hit will be on final drivers and game code. In game development time frames there is plenty of time to bring performance up to acceptable levels.
Is it me, or does the RTX shroud look like a cheap fan-made concept model?
Looks good to me.
I think Alex forgot motion blur ON. LOL!
Im not an early adopter but I will have my eye on this, looking to be our next step forward in gpu's and it's going to be really cool seeing what can be done with this tech a few years down the line when its more established
1000$ can't maintain locked 60 FPS on 1080p. RIP
Its future tech its always expensive at the beginning
2 reasons:
1. Games not optimised with Ray Tracing yet
2. Ray Tracing in video games is incredibly new and ray tracing rendering IS next gen.
yh im going to get a 1080ti then nextbyear gonna sell it and get the new nvidia 7nm cards
Cyber Dragon Probabaly because most of these idiots don’t even know what ray tracing it and how big of a deal it is to be able to do it in real time.
Only when you have had to render for hours in the last on your project then you will know how big of a deal it is.
@@SonicSP Raytracing is nothing new. The final rendered product is what matters to pc gamers and if they have to pay $1200 to barely get 60fps for better shadows and lighting then many will be disappointed.
I didnt like alexs voice. But now i dont mind it... becuase his hair is so much worse. He looks like a create-a-skater in tony hawk american wasteland
You guys are awesome, very informative thank you!
From right to left looks like a graphics comparison.

Don't worry John, 1080p, texture filtering and some AA will fix you right up.

Useless gimmick that kills the FPS
Just like HairWorks and PhysX
Expand DeadMeme If it hits 60, it would be enough.
uh huh...dynamic lightning is a useless gimmick. Thats why RT has been standard for any CGI since the beginning of 3d modeling......
@@SonicSP no, sonic, it won't. High refresh rates is all the rage these days, more so than 4K etc. And even then the tomb raider demo couldn't hit 60 FPS at 1080p on the highest end card. Battlefield 5 could hit 60 at 1080p wow. But I think people who buy high end card with their 1440p 144hz monitors won't sacrifice resolution and framerate for one graphics setting.
If it could hit 60 FPS on midrange cards (which they won't since they won't even support RTX), sure then it's fine. You have to understand that people expect different things at different price tiers.
@@Grammostola a movie can spend a year to render to a 24 fps clip. Gamers demand more than that and while it's the end goal, right now it is a gimmick because it's not worth to cut your frame time in half, even worse with the 2070 etv
wile123456
RT in real time rendering is an indispenable step towards the next level of visual fidelity. It might fall short this gen, but just like programmable shaders it`s something that will stay and grow more and more important with every iteration.
I remember being blown away by Nvidia's Tegra K1 presentation. Then John Carmack said, "Nvidia's claims about the Tegra K1 should be taken with a couple grains of salt."
I'm wondering if he'll do the same with Turing.
2:11 guy on the right is rendered with a Pascal gpu
guy on the left is rendered with a Turing gpu,you can even see the ray traced reflections on his watch and glasses
Sooo much PR bullshit in this video, Ray tracing is a great feature but we need to wait many years RTX cards are to weak and that is reality.
froget67 Maybe learn how to spell before you post.
Guess u didn't watch the whole video son
That's basically what they concluded. Good job.
You're right, but it was hard tto watch for me I was really disapointed with performance of this cards especially in TR ... and price is waaay to high
Another thing consoles only can dream of lol
and the majority of PC gamers...
@@Ionic0 nope. We will get it in a price of sony soapstation gamepad ;-)
@@Ionic0
Not right now maybe. But the technology will get cheaper over the years for PC gamers while console players will have to wait for another decade at least.
How many PC gamers actually upgrade to the latest graphics cards when it comes out? Very little, due to the cost. Hell according to Steam, the average PC gamers specs are equal to or even weaker than the current gen consoles. That says it all.
smarm smarm smarm what an attractive quality
0:47 "Nascent"
Oh gosh that's so unsettling
most well reasoned analysis of this launch I've seen yet
To bad PC gaming these days is only early access, mobile, moba, csgo and PUBG which run on every laptop.
R E You’re referring to exclusives, I’m fairly sure PC gaming is more than that. My library attests to it.
there is still a big chunk of the good stuff :)
It's the greatest rip off in gpu history. Shame on DF.
Irishgamer01 Go buy AMD’s once they have an equivalent card in 5 years.
I remember ray tracing being talked about by a Silicon Graphics rep back when the Ultra 64 was in development and how it could do it, no problem. This was with Robotech and Final Fantasy tech demos being shown. Might've been a Next Generation magazine now that I think about it...hmm...a long time ago...
Finally, a media outlet with an opinion that I 100% agree with. Also agree with the the thoughts on Jensen's Keynote, it was well presented, informative and entertaining.
"Raytracing is the next thing in graphics!" A constant mantra back in Amiga 500 days.. ;)
I really enjoy your videos! Good work!
I wish the next big thing in graphics was super high res parallax textures on everything.
If you want to see an example of deep learning super sampling, have a look at the NGU algorithm in MadVR. At the moment it uses the whole FP32 section of a GPU just to run the algo, so if nVidia can do something similar on a 4K image using the tensor cores then they have a winner.
I have waited for you guys too realase this video
The fact that we're at raytracing in video games is amazing and it is something they should be working toward, but this does seem a little early. I expect NVidia is doing this to get out of the gate early and be a leader in this technology. Right now this is for the 1% of gamers, and for probably a few more years it's waaaay more practical to use inaccurate shaders where most people wouldn't tell the difference without toggling settings.
I wonder how this may be better in the end when they implement ray tracing selectively (for reflections by example)... I mean if Killzone Shadowfall was able to sprinkle some raytracing here and there on the original PS4 these dedicated cores would be able to push more realistic/faster implementations at higher resolutions, etc. (I'm disappointed by the leaked raytraced demos performance so far... I know I'm not comparing apples to apples here).
The thing I want to see, is when realistic shadows are projected onto the scene, and not only can _you_ react to these shadows, but _enemies_ can react to them, so that in a stealth game, maybe you're around a corner or on a rooftop, and the enemy cannot see you, but if they can see your _shadow,_ especially if they see it move, then they can freak out about it.
It could be better though. If the AI were designed to be able to know when it can draw line of sight to the player, then it could theoretically be designed to draw line of sight to the player's shadow. That might be an expensive calculation to make, but it might be possibly to pass it off to these GPUs.
I don't claim to understand the technicals, but couldn't you run the core of the AI on the CPU, but also have an element that does some fairly basic "shadow checks" using the raytracing elements of the GPU, and then passes those to the core AI routines? There might be some latency there, but so long as it updates every second, or ideally 1/2 or 1/4 second or so, it should be sufficient to cover _just_ the "hey, did that shadow move? I should look for guys!" response.
This tech has me most excited for a future with more emergent, immersive gameplay possibilities utilizing real-time reflections. I think about the stealth of something like The Last of Us, but instead of "listen mode", you use broken mirrors, puddles, reflective surfaces to scout your surroundings.
As a paying PC, xbox one x and switch customer i'd like to thank you guys for your continuous content.
The technology has promise, and we've definitely made huge strides, but it's still just a little too early to be viable. Still, having it accessible in a consumer product lets developers play with it now and hopefully futureproof for later, more powerful RTX-enabled cards.
i remember ray tracing was gonna be the hotness 15 yrs ago, nice to see it finally arrived .
Then what was the purpose for GPU tech to implement unified shader approach?
No matter how nice nvidia put it, RT at dedicated piece of silicon is a step back in the industry. I'd go so far to argue that it simply steps taken to further saturate exclusivity.
cyberpunk 2077 is probably going to be the next best game ever,and it does not need ray tracing.These gimmicks are too expensive and dont really do much for gameplay.
How can you say they don't do much for gameplay if you haven't experienced it yet?
Use a little imagination. Being able to see you just narrowly avoided an explosion off screen or someone behind you in a reflection could have a HUGE impact on gameplay. The adrenaline rush would be insane. Plus its not all about FPS, for games that are all about the atmosphere it would make an even bigger impact.
Anything that replaces the need to use trickery and "fake" techniques with more dynamic and physically based techniques will always be the most important advancementw in my opinion. People want bigger textures, people want bigger resolutions, but a well done 2k PBR texture will always fit better into every scene and hold up more accurately than a well done 8k oldschool texture.
It's going to take a few generations but this will be a fundamental way of doing lighting just because it IS lighting. No more ambient occlusion, no more global illumination, just lights that shoot rays and object that reflect it. There wil obviously still be artistry to enhance things but this technique coming to real time is so exciting.
Uhh nobody uses a 2k monitor (2k = 2048x1080)
Been refreshing youtube waiting for this video for a day
I use a 144hz 1080 panel, the results will be interesting, and the scalability of effects once RTX is enabled will be paramount to get a nice balance. A huge technical advancement by NVIDIA, and a brave one too.
Anyone who was paying attention to the Titan V would have known that the Tensor cores were coming to gaming GPUs. Shortly after Volta was out Microsoft announced DXR, and with it Nvidia announced RTX, and AMD talked about the Vulkan equivalent. AMD, as far as I know, have stuck to talking about this with Radeon Pro graphics, and have talked about their use of FP 16. (AMD haven't said anything explicit, but this in theory opens up the possibility of some manner of ray tracing support on Vega and current gen consoles.) Nvidia, however, talked extensively about how they were using Tensor cores as an intrinsic part of their RTX. They hadn't mentioned the RT cores at that point, but it's obvious that if your entire Directx gaming ray tracing solution requires the tensor cores (and they said that the feature was only compatible with Volta up) then in order to take advantage of it their gaming cards *had* to include tensor cores.
tl;dr no one should have been surprised by tensor cores in gaming GPUs.
I bought a used Asus rog Stix 1080 Ti for 475$ yesterday not much of an upgrade from the 1080 but still I'm pretty stoked.
I enjoyed the HairWorks 2.0 comment, while RTX is not quite that trivial, I think a more apt comparison might be Vulkan which is another great technology that just isn’t being adopted much.
Nice of Digital Foundry Bring more one in the board to debate Good Footage !
