i just linked you the evidence that says they aren't.. Directly from nvidia. RTX tech from nvidia is part of the optix package which is listed under gameworks features.. how you can say thats mutually exclusive is beyond me.

From nvidia's own site: https://developer.nvidia.com/what-is-gameworks

Fair enough, I did a ctrl+f search for each respective name and it came up with nothing. nvidia are only hurting themselves by catalouging it with that the gamesworks brand, they must know the name is dirt.

Doesnt get away from the fact that people who associate it purely with gamesworks didnt understand the tech before this announcement, probably still don't get the importance, and cant see past the gamesworks brand.

Ermm, Larrabee was a GPU that got canceled back in 2011? It was also slower than NVidia and ATI and not sure why you think that shows you know what RayTracing is?

To me, RayTracing started way back with the Amiga days (might have been earlier but no idea) and this is what got me excited all that time ago (looks crap nowadays but anyone with an Amiga or similar will understand)


If my post came across rude, that wasn't the intention but serious real time RT does get me all moist :)

If you have to ask "why ray tracing", he's right.

Raytracing = on the fly volumetric light rendering.

Amazing if you’re rendering still images and have time to appreciate and manipulate composition, but as a global setting it is entirely pointless performance hit.

It's not volumetric light rendering, it's pixel vector shading. You take 1 pixel on your screen, fire it directly in front of you, and trace it's route back to a light source.

My post wasn't intended to suggest that Intel created Ray Tracing.
It does show that Larrrbee was indeed moving to RT as rumored and had improved to use both RT/rasterization.
The notion you put forth regarding knowing about RT was hackney and stilted towards what was presented to you. Intel's involvement regarding ray tracing.
So no I take no offense however, I do want to take the opportunity to explain the post since you didn't quite understand it.
:cool:

That’s the same thing. And has been a thing for quite a while. The traditional methods are are CPU based renderers which take a life time and a day to render a single scene.

Fair enough and good stuff. Being an old man who has to go to work in 30 mins makes me come across as grumpy :D

NP, what I was alluding to is what might be in 2020 once intel comes to market with it's GPU. It's not hard to assume that Intel's GPU might be a Ray Tracing juggernaut. Intel, unlike AMD does have the capital and resources to shift the gaming market as a whole. Nvidia may have gotten wind of it and is trying to be competitive now to pre-emptive inclusive IP measures to lock down raytracing. So that Intel would have to come to Nvidia for licensing of the IP.

Again, just a guess. But to me explains this weird shift to ray tracing all of a sudden. Something that's been around since what the 1990's?

No, volumetric lighting is taking a volume of space, and filling it with light rays to simulate shafts of light. The very benefit RT brings is doing away with the effort of forcing scenes to look like that - put light outside, draw window, volume of light creates itself. Not the other way around.

@drunkenmaster as far as i can tell nVidia have added nothing to Ray Tracing, it already exists in some game engines to the same extent, some of them years old, and it does not need dedicated hardware to run.

Its as if nVidia have taken existing technology, recoded it to require their hardware and then run really not very well at all for some planed obsolescence.

I think you should watch the Spiderman scene from Siggraph, that shows what their system is doing and that hasn't ever been possible to complete like was shown. It isn't any good for games but it is ideal for rendering in design based workloads and movies.

That’s how volumetric lighting works. If you think on a larger scale everything is relative to a single source of light.

I care because it's never been done in real time before and also because of this statement from the keynote yesterday:

It has been done in real-time before and there have been other RT GPU's. The only difference here is this is the first PC gaming GPU that does ray tracing. RT is something just about all the main GPU makers have been working towards and talking about for years. Even outside the PC market.

RT is like any other feature it can be implanted well or it can be implanted poorly. RT doesn't have to kill FPS and it doesn't have to make everything fake and over shiny. That's up to how the devs make use of RT.

RT can also be used for things other then graphics like AI and other areas but that problem with that is it would require RT as a minimum spec.
