@fourthline: I think after reading you post, and then reading the following comments on the post i have come to the conclusion that you dont have a fundamental understanding of what ray tracing actually is. AND THAT IS OKAY. I think the folks pushing this technology have done a pretty poor job of explaining what it actually does. And its hard to just show it because in the years leading up to the development of the tech, game developers, and 3D artists in general have done a pretty decent job of faking it.
To understand how it works, you first have to understand how real light in the actual real world works. Sadly im not smart enough to explain it well here, but essentially light comes from a source in beams or rays. Ray tracing is a real time simulation of the physics of light traveling from a light source and the way it would react with objects such as reflecting or scattering.
in the past lighting effects were done more or less with tricks. think if you were to draw a candle lit room on a piece of paper by hand. you would draw the objects closer to a candle brighter than the objects farther a way. this of course is an overly simplistic explanation of how they do it in games but i hope you get the gist.
Now to answer you question of can your Xbox one X theoretically do ray tracing.
yes and no.
Ray tracing is extremely complicated math and required dedicated processors to run it. which is why Nvidia RTX cards have dedicated RT cores.
that said they have done ray tracing on hardware that doesnt have RT cores, but as far as i have seen it doesnt really work well. think a Nvidia GTX 1080, which still plays most games at ultra 1080p 60+fps would be down to single digit fps on low settings if you turned RT on. At least that is my understanding.
