Neat!

Too bad no one can get a decent modern graphics card for less than double MSRP for the foreseeable future. or it might be more exciting.

Another useless effect that will never be implemented because games are now developed for consoles and ported to PC. Kudos for the effect, but seriously it will be marginally used.

There was a second real-time ray tracing engine released today as well: https://venturebeat.com/2018/03/19/otoys-octane-4-blends-cinematic-video-and-games-using-ai/

OTOY also collaborated with ImgTec just before Apple dropped them.

Wasn't AMD showing demos of Real-Time ray-tracing since 2006? Also no longer the holy grail in 3D rendering. Bouncing light takes too long and isn't too accurate going through certain materials. Now its bouncing sending a ray from the pixel until it bounces a certain amount or leaves the scene.

Everyone's been demoing the tech for awhile. Last year (CES or maybe GDC) Imagination was demoing a 15W chip that was trouncing a GTX980 (IIRC) in rendering a scene using their ray tracing technology. The imagination chip was rendering the scene nearly instantly while the 980 took 5-10 seconds. Still, not many have been integrating the tech into engines or GPUs. It is possible to ray trace on modern cards, but not in real time. We still haven't a clue how good the technology is going to be. Unless we are to believe the leading image is a screen grab from a live demo.
