Very nice. It’s nice to see they’ve got some animation going, as that was missing in these types of videos for a long time. I have to wonder, though, if customers/players will accept the way it gets noisy when you move the camera around, as it’s recalculating all the samples. It seems pretty distracting, like the texture streaming in RAGE. With traditional real-time rendering, the image isn’t as high-quality, but it’s more stable when you move around. I’m not sure if the real-time path tracing is going to be usable for games with that kind of issue, but there are other applications, like architectural visualization, where it would be awesome. And hey, just wait a few years and GPUs will be fast enough to do a lot more samples per frame and reduce the visible noise. :)

remains to be seen if there will be shortcuts that get something similar with less horsepower.

dice is in charge of alternate methods at this stage, and theirs looks pretty good too.
