Yeah that linked video looked bad. Personally I'd prefer getting the cycles engine running on PS4.

No chance. We won't see real-time raytracing (in games) anytime soon. Even a high end PC, with a few Titans installed wouldn't be able to run a modern game with RT.

that was pretty coo, video.

Even the next generation of PC GPU won't have enough power for ray-tracing.

The current high-end GPUs have no power to make games using ray-tracing insted rasterization... Ray-tracing today can be used only in prerendered schenes.

nVidia didn't expect real-time ray-tracing for games in GPUs before 2015... and that's before the actual generation of next-GPUs are delayed to the next year.

I suspect we may get a small downloadable game or two which are glorified tech demos at some point. But that is about it, and even that is a maybe.

Ray tracing is just too costly to use. Though I remember when Intel was pushing for Larrabee they had Ray tracing working in Quake 4.

Not sure if it needs to be Ray Tracing - it can be Voxel Cone Tracing

Ray tracing is just another level over rasterization.
