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...
