Crossplatform Ray-tracing doesn't work?

I just tried inviting my Xbox One friend to a Win10 ray-tracing demo world.  it didnt work.  he can't 'enable ray tracing.'

Did you guys seriously sacrifice a fun, functional VR version for a PC only graphics update?  who the hell are you even catering to?

IF MINECRAFT CUSTOMERS CARED ABOUT GRAPHICS THEY WOULDN'T BE PLAYING MINECRAFT.  FIX VR!
