Those game demos are really impressive-- using DirectX 12 and some kind of new
raytracing API. But it got me thinking about *how* this real-time raytracing
technique works-- given that GPUs are not suitable for speeding up raytracing
calculations (based on lots of past comments here in the newsgroups, anyway.)
Apparently, only *some* aspects of the game's visuals make use of this new
API+GPU strategy, the remainder relying on the usual rasterization techniques
(AFAIU). Take a look here...

As I understand it, GPUs have advanced far enough that there's no longer
a show-stopper preventing POV-Ray from making use of GPUs for rendering
scenes. It's *only* (LOL!) a matter of rewriting POV-Ray from scratch so
that similar rays are bundled together and processed in batches. Or
something.
