The xbox isnt named the xbox series x. Its just called "The XBOX" which is part of the series x. They made this correction to our understanding like a week or 2 ago.

My name is Ray, and i can trace just fine without a fancy computer.

True real-time full ray tracing is still a decade off at least. All we have now is partial hacks and it looks like crap with most implimentations. Low frames for shiny surfaces, wow! Most people would gladly turn off reflections and shadows to have a playable game with a smooth frame rate. Make better games. You got a chip for that? Lol.

Of course you need specialized hardware to do REALTIME Ray-Tracing. This annoys me.

Considering you're only mentioning lighting here, don't forget you also have shadows, reflections and ambient occlusion and refractions....

That Crytek demo makes people think RT is easy and can be done on any hardware. Well no, not at 30/60 fps.
Event that, without using RTX, it runs pretty slowly and requires expensive GPU too. Might as well buy one with specialized RT hardware.

Real-time RT is a revolution, not a "thing we could do for years and we have hidden it cause for marketing reasons"

 But RTX cards are expensive and out of my price range and I am AMD fanboy so ray tracing is fake.

J/I
I have rtx 2080ti

The Commodore 64 can do ray tracing. This article is terrible.

Cool, but if you read more than the title you would realize that the PS2 already had, like the RTX cards you mention, specific hardware tricks (mainly possible thanks to its particular architecture) that allowed better performance than agnostic CPU rendering or offloading the work to the shading units.

Even my old intel hd can do RT. with very low fps in real time. Nothing new. The point of RTX is the card can do REAL TIME in real gaming scene, not just simple poligon and light.
