Why would they even bother with a ray trace version?There is a video but I'm on my phone so I cba finding it, soz!
Any video of it running? Big thing holding back ray tracing is image grain. Essentially they don't have the power to render at full 1080p, so they have a post render system that cleans up the image. Machine learning is the big buzzword they're using to say ray tracing is here.
I guess they're getting the ray tracing ball rolling, to encourage more work on it and next gen it'll work a lot better. Seems like there's not much reason to upgrade from the 10 series for these, unless money isn't an issue for you.
