We aren't ready for RT when it sets us back entire generations of graphics performance...

Of course they like the raytracing approach. Because they are lazy bastards and just blasting rays at things and recording their bounce is literally the most brute force approach one can think of. ANd no, itz's not art design and workarounds. I call BS on all that which is yet another NVIDIA's attempt to make everything we had for years gone from the history because now thy have RTX. Just like they erased alt he physics when they pushed PhysX.

Here's CryEngine from 2014 doing actual realistic real-time reflections:

There is nothing pre-computed or fixed for doing this. Engine simply has to do it in real-time because you can actually see individual items from the world inside the reflections. FOUR YEARS AGO (at least video was made then, which means it can be even older). Four years in gaming industry is like eternity. So, there's that... Sure ray tracing looks more precise, but do we really need that kind of precision NOW when they clearly can't deliver good enough performance? Frankly, no.

Another one...

...from 5 years ago.

Skyrim engine from 4 years ago (with some mods I'm assuming)...

Perspective and distance correct reflections.
Yeap exactly what i was thinking.

Why? RTX a weak card?

Ray tracing is basically a geometrical optics approximation. It's fairly straightforward solution that solves a lot of problems with reflective surfaces, transparent and reflective, soft shadows from area light, ambient occlusion etc. We have a lot of tricks now in forwards/deferred rendering paths, that make life a lot harder if you will try to achieve at least something similar to what ray tracing can do simple by design. The only problem is performance. It's really good that someone with a market share and resources pushing it. Look at OTOY and Brigade, and Imagination Technologies hardware they demonstrated with UE4 ray tracing few years ago. It is possible if you are willing to make a dedicated hardware. I hope that AMD and Intel will hop on that train soon and it'll end up in some next generation of consoles to speed up adoption.
Works cited please or you lie.

Downgraded how or why? Compared to what was shown in the RTX demos? Probably. On the other hand we would not want all the excessive effects like all very reflective surfaces or badly performing stuff in actual games anyway.

Doesn't seem "weak" so much as a "two steps forward, one step back" sort of thing. Real time ray tracing sounds cool, but not if it cripples at 1080p.

Maybe you should look up QuakeRT or Pantaray. For people like me that remember weird stuff, this whole RTX thing and the discussions behind it are hilarious.

https://software.intel.com/en-us/articles/quake-wars-gets-ray-traced
Why hilarious?
2004: 40 Xeon CPUs doing RTRT in Quake3 at 512x512px @ 20fps - called a great achievement (I remember this one from the press).
2009: 4 Xeon CPUs doing RTRT in ET:QW at 720p @ 20-35fps - fantastic, finally usable without HPC.
2018: a single GPU doing RTRT in BF V at 4K @ 20-30fps - awful, pointless.

And even if you play ET on highest settings and BF on lowest, the difference in details (and minimal requirements) is just enormous.

Are RTX cards too early? Not for those that are fine with 1080p. Everyone else can wait until RTX cards match their requirements. What we have is a PoC, but also a consumer product that gaming studios can work with.
It really doesn't matter when RTRT would be included in GPUs, because it would always mean a significant performance drop from a level that we would be used to at that point.

"Amazingly, this happened in 2004, a time when most people rejected the concept of real-time ray tracing. " - nothing changed.

Asks question, yet gives exact answer.:roll:

But really, Ray tracing for lighting has been used in movies to cinematic effects for at least a couple of decades now, but not in real-time. Peter Jackson was quite the tech investor when he started on the Lord of the Rings Trilogy, and those movies have been out forever. :p Anyway, with that said, the idea that ray-tracing would enter the gaming arena has been worked on extensively by all players in the CPU/GPU field, and the idea that such effects would potentially cripple a system aren't new either, as you've pointed out. So devs need to very carefully balance the effects vs performance for all GPUs not just "in general", but now quite specifically, and that's a lot of work. We should be commending the effort that is being put into this tech now. If anyone thinks that DICE has delayed a month because of RTX alone, they are greatly mistaken... it's been part of the engine since day one. The only thing that has changed, maybe, is the specs of the cards that support it, giving them a clear line in the sand that they need to optimize to. But given the huge size of this franchise, they should have had such data for a long time, and if they haven't, well, that's hilarious to me as well.

GPUs faster for graphics processing tasks, who knew :p? I don't find it this amazing since they had to portion off space on a humungous GPU for dedicated HW to handle RT or some aspect of it. I'd have been amazed if they implemented it without an enormous penalty.

To be honest, Ray Tracing isn't really a very efficient task for GPUs. RTRT is still far from playable on GPGPU - that's why Nvidia went for RT ASIC.

Actually, RT is more like tasks that we usually run on CPUs. Each ray (or group of parallel rays) is traced in a single thread. It moves through different matter, it bounces and diffracts. It's a complicated serial problem and running it on GPGPU means massive number of cycles.
CPU rendering workstations (high-core Xeons) are still doing pretty well agains best GPUsdespite having 50 or 100 times less cores. :)

So not because of Caustic Ip then expert?.

As Cadeveca points out , Nvidia reinvents wheel, we're not convinced, they buried Caustic over ten years ago Afaik and they Had working Asics that they said could scale well.

Nvidia bought and buried them, and now ten years on ish , look a wheel.

Nope sorry it was imagination technologies that bought Caustic ( i am stressed at work atm ,brain ache inc)

And they sell add in cards apparently

Still No ty Nvidia.

LOL so those hardly noticeable differences in the demo will be further toned down - probably so 1080@60 is possible. PS4 Slim performance brought to nvidia cards!

The only reason why it was "impressive" back then is "holy shit, we can actually have this thing moving", because till then, only time we could see such graphics were rendered on rendering farms for hours or days (offline render). When you just have variations of existing, it's less impressive.

Make no mistake, I can't wait the day when entire scene will be ray traced in real-time at 60+ fps at any resolution, even 4K or more. Basically, from there on, we'll basically reach peak realism, only thing we'll be able to build upon will be number of rays and bounces used. And more work on textures and models. There won't have to be "creative" part to achieve effects, they just happen naturally then. But we're still far away from there.

Imagine current ray tracing maturity being somewhere on the level of first pixel shaders when everyone was obsessed over them and they basically only used them to make water...

In fact the PS3's CELL was capable of Real Time raytracing on one of the daughter cores, and I believe it was used in a couple of games (looked really good, though of course 720p@30Hz is all it ran at).

Wake me up when we can do it in 8K@480Hz. Imo we should try to reach 8K and ultra-high framerates first so we can actually notice the difference in quality.

At the Siggraph 2008 event, NVIDIA demonstrated a fully interactive GPU-based ray-tracer, which featured real-time ray-tracing in 30 frames/second (fps) and a resolution of 1920 x 1080 pixels. The demo saw NVIDIA flex its muscle with using almost every element in ray-tracing for which technology has been developed so far, namely a two-million polygon demo, an image-based paint shader, ray traced shadows, reflections and refractions.

Not a new idea, either, which adds to the hilarity. Let's jump back to 2006:

Ray tracing has long been considered too expensive for mainstream rendering purposes. Movie production studios have only recently begun the transition to using it; however, the true cost of ray tracing has been very poorly understood until recently. It is now poised to replace raster graphics for mainstream rendering purposes. Its behavior is very well suited to CPU processors, and scales well with hyper threading and multi-processor configurations. The traditional cache hierarchy associated with CPUs is very effective at managing the external memory bandwidth requirements.

Checkout the BFV RTX video by JackFrag. A soldier's reflection popped into the window glass, when it entered the "tracing volume" (probably about 100yards). How realistic... could have done a simple blend or something to ease the transition. They likely will for the final release.

This is the first product that makes RTRT at home possible in real-life gaming. At a decent premium, sure, but you don't need a Xeon server or a cluster to do it. How is that "reinventing wheel"?
Sorry to say this, but it seems like many of you just heard about RTRT for the first time...

Of course the idea isn't new. But the consumer-friendly implementation is first and should remain unmatched for a while. That's the great part.
RTRT itself is nothing special... at least for me.

Again: it seems like some people here just had their first contact with this idea. But they quickly found info that someone has done it already 10 years ago, so it's clearly nothing special.
I guess on this forum the only exciting thing about games is more fps. Booooring.

But it highlights the price of the initial cards. It's a lot of cash for minimal return on effects.
Same can be said of the 10 series cards for 4K. But ppl werent complaining too hard on that

Look ,I think genuinely you're stuck in your own perspective here, you have a 1050 so clearly game at 1080p , even console gamers are edging away from 1080@60.

I will likely get one somehow at some point jyst to try , but I insist on high res and Qi so it's not for me, i know this.
Still I'm not saying it's rubbish just that it'll be rubbish to me and many others.

And RTRT isn't new, you definitely are not the only one who knows what is what here ,you talk a lot, doesn't mean it's worth reading.
And Nvidia invented a cheaper(in computation) algorithm and the hardware, to run a less then equal version of Raytracing (it is not fully Raytraced) yet still heavily impact performance , im not paying over odds for that.
By the sound of it a 2080ti should play pretty much any present game at 4k@60 without Rtx or some games with Rtx on at 1080@60.

Those two resolutions work just fine on my monitor but do you really believe I or any other 4k owner Ever goes down to 1080.
Also because of this ,ie a 2080/2080ti owner is going to connect it to a pretty Decent monitor, they're not then going to be happy playing the Latest AAA games at 1080 and swapping back to 4k for everything else ,so i expect dev adoption to die off, even with big NV money about.

It's sad too because RT sounds like it could be very cool if it could be done without a massive performance hit. However I personally think Nvidia intentionally left RT performance horrible. This allows them to 4x their RT cores with 7nm Ampere, and claim ridiculous things like 4x the performance of Turing!

You should keep using the 1050 card strategy. It's really going well. :)
I don't game on the PC anymore. 1050 wasn't bought for gaming anyway.

Well, we've already established that my knowledge is limited by what I read and your comes from owning. I do hope you'll get an RTX card at some point and your rendering knowledge will explode. It's worth it. :)
And Nvidia invented a cheaper(in computation) algorithm and the hardware, to run a less then equal version of Raytracing (it is not fully Raytraced) yet still heavily impact performance
You have literally no idea what you're talking about. :-D
1) There's no such thing as "fully raytraced".
2) Nvidia's RT approaches are among the most advanced available today. Sure, RTRT is nowhere near professional renders or even movies (which Nvidia is famous for, BTW), but RT cores speed up serious rendering as well. It's a huge achievement. And it works in tandem with tensor cores. It's just a showcase of technological supremacy.
These first RTX cards being successful or not is another story - we'll see some sales statistics after the launch. IMO the preorder looks promising.
Nvidia can now build professional rendering machines around this new tech, so the R&D will pay off anyway.
