Renders like the one you showed are obviously a lot different than real time rendering, since there is no limit to what can be shown in a picture when you're spending hours rendering a single frame in a proprietary environment like 3d Studio or Maya (rather than OpenGL or Direct3D).

It just seems odd that with all of the amazing advances in hardware and ray tracing technology over the years, real time ray tracing demos generally look like ass outside of the reflections...
I've found most ray-traced demo's don't get into textures much which is probably why it looks like a 10yr old CGI video (except for the reflections/lighting). Combine the power of ray-tracing with a fully HQ textured scene and you'll get something that looks damn near real (and probably not real-time). The very fact they can do some of this stuff real-time is a testament to the power of modern processors.

In our lifetime we are in for a treat consider the power of GPU's 10 years ago to their power today, if Moore's law keeps up consider the progress 10 years from now, and 10 years from then. We will see photo-realistic graphics in our lifetime if not within 10 years.

Good to see Nvidia pushing ray-tracing forward

Interesting, wasn't Nvidia's PR telling us all how stupid ray tracing was about a month ago?

it still might be, but if intel is going to push it they have to adopt and get ready

Is it impossible to mix ray-traced scenes with regular stuff?

I love the total lack of jaggies.

The 2 main issues I have with rasterization are depth precision (in DX, not opengl) and aliasing; if those 2 could be abolished then I would be happier than ever before in my entire life.

They're using some excellent aa. I've never seen aa that good in a rasterized image.

It's Dusk. Anyway, while that's interesting, I think it'll be a while before ray-tracing will be used in mainstream. Even if it is, it'll probably not be used exclusively, since there are things rasterization is just plain better at.
