Yeah, I was not referring to project Lavina. What I meant was this video ->I don't think they using hybrid GPU rendering in thad video (GPU+RTcore+Tensor core). Maybe It's just using RT core only. I'm not sure. And I don't know how effective this experimental V-Ray GPU build with a pre-release Quadro RTX 6000 and driver. If you compare it to Unreal RTX video, they are using hybrid rendering (GPU+RTcore+Tensor core). I'm not sure too if maybe unreal engine build itself in the RTX video, is better than 3ds Max & vray for realtime ray tracing capability.
Thanks for the info (probably from videocardz, right?) but at this point I don't think anybody from Nvidia confirmed that the NVLink on the Geforce RTX line will actually be enabled. I mean it sure looks that way but I guess we'll have 100% confirmation on Monday. Don't want it to be just a PCB tongue that does nothing. Exciting times for sure though!No, it's from a chinese guy some days ago. Well, just wait until monday tho...
As for the ray-tracing on the GPU in games... From my understanding, yeah, you can do partial ray-tracing which is what the DXR / RTX do. You can trace reflections, maybe a couple of light bounces but its still fairly crude compared to an offline renderer. Like really crude. So I politely need to disagree with you on that.Sorry, my previous comment is wrong. I already edit that. Yeah, the quality from real time path tracing from unreal isn't good enough if we compare it with the raytraced CPU render quality (offline render). But now, they support the real time raytracing using RTX GPU (Hybrid rendering using GPU, RT core & tensor core).
Yes, pathtracing on the GPU is being done since they went the whole GPGPU route. That said, even today, even in the Quadro 6000 offline renderer demos it still is not real time - you still get noise, you still need to wait for things to clear up.Do you mean this video?
This video is a screen capture of one of several demos being presented using standard vrscenes exported from 3ds Max and Maya. It has Project Lavina running on a Lenovo ThinkStation P920 workstation with a single Quadro RTX 6000 for its GPU. Everything you see is purely ray traced and runs at real-time frame rates at HD resolution. The materials and lighting are direct conversions from the vrscene, and we’re enabling one bounce of global illumination.
You’re looking at over 300 billion triangles, rendering in HD at 24-30 frames per second – in real-time, with no loss in detail.It doesn't mean offline render. They said "screen capture", it can be done using Bandicam or etc. The settings is using 720p, and it gets 24-30 fps in realtime, with over 300 billion triangles on that scene. It using real-time Chaos denoiser written in HLSL that also allows it to run on almost any GPU. Btw, they just enabling one bounce of global illumination.
Or Chaos group could buy out the FStorm dev. Could you imagine what he could do with their resources and team behind him?Then the FStorm guy resign, and make his renderer again based on Chaos source code :))
I've been keeping tabs on the rumor mill for the new RTX series and what excites me the most at this point is that it I've read quite a couple of rumors that say that even the Geforce cards will have a NVLink connector. If it works then that means we'll effectively be able to double the RAM by going multi-gpu (afaik it works only in 1+1 mode so with an 8gb baseline card you'd get 16gb of VRAM if you slot more of them).
@soso
As for you comment about nvidia predicting stuff... Theatrical marketing promos sure do predict a lot but the actual reality is sometimes not quite as clear cut as most companies would like to admit. Just remember that real time raytracing was about to breakthrough in like the early 2000s, or was it the 90s? We still aren't quite there are we? :)
Are GPUs generally more powerful than CPUs at parsing C++ source files? I wouldn't be so sure about that.I'm not a developer. I'm just an artist. But, can it be done in hybrid (CPU+GPU+Tensor core) way ?
What exactly does "ray" mean in this context? Is it just computing a single ray-triangle or ray-box intersection? Is is traversing the whole scene and finding out which primitive did the ray hit? Does it also include shading the hit, evaluating all the maps, etc.? Is this just for coherent primary rays, or are the numbers still the same for the wildly incoherent secondary rays? You're comparing two sets of numbers which can mean very different things.I think yes, it really has the CPU ray tracing capability, according to Jensen Huang. Watch from:
Ad speculation about 2080 - I'm not following the news, are future consumer GPUs supposed to feature the tensor cores, or are these just a quadro feature?I think yes, like the Tesla V100 and Titan V (both are volta architecture). Both have tensor cores. I think it applied to the Geforce RTX too.
I mean, to tell you that with this new invention, CPU render is not interesting anymore, maybe in 1 year later from now. Who knows? And people will try, or even switch their pipeline to GPU related render engine. Nvidia is already predicts it since some years ago, that GPU is the future for Film/CG/DCC/Design/Visualization industry. That's why they increase the VRAM in Quadro and Tesla like crazy, more than their gaming GPU (Geforce). Then, they add the Tensor core and RT core in their new GPUs.Do you know I'm just messing around with the Corona team to wake 'em up. And I hope they are aware of it. Look at this:

I guess that I don't really have to mention that we knew about project Lavina before this blog post went public, right? ;)
"the GPU has much more powerful CPU (RT Cores) than the most powerful CPU's this days."
Are you sure? I mean, in real scene, in "normal" office?
Now we have 32 Core CPU (1700 euro). And, next year, maybe 64 single Core CPU
Do you know that the new Quadro with 48 GB price is 10.000 euro!?
And you need a specific software written to this architecture.Do you know I'm just messing around with the Corona team to wake 'em up. And I hope they are aware of it. Look at this:
You cannot simple switch from CPU to GPU.
Also all our plug-ins must be converted etc...
Maybe in 10 years all rendering engines (also Corona) will run on GPU with RTX technology.
But, now, it's only a preview. It's like "look at the direction we are going". Only very big company can buy these card.
And you need a specific software.
Sorry, day 1 is not happening as we were a bit delayed because it's currently flu season here. We're preparing a new 2019-enabled build of 1.7. Please let ourGot it! Nice! Since I'm using v1.7.3 for my main render, not the daily builds :)monkeysdevelopers and testers have some fun with breaking the new build before we release it on monday :)
Corona was listed as one of the many partners that committed to deliver day1 updates for max19 according to autodesk, so one can only hope that actually happens :D would be amazing if we didn't have to wait weeks and months for new releases to be production ready like previous years. I understand its a big task with so many companies and plugins etc, but nothing worse than having a new toy that you can't play with because it didn't come with batteries ;)So do Vray... They already released for max 2019 yesterday! I think corona team might working on it and release it soon :)
