Ray tracing is not worth it at all on any platform, PC included. It's the latest buzzword from Nvidia to sell overpriced cards to PC idiots race. It was basically impossible to make the whales pay $1000 or $1500 a new graphics card without some kind of justification. RTX is that, a giant waste of GPU power. In the real world, you have tons of options to get nearly the same lighting results while paying a lot less in GPU power. But then, how do you get the money from PC whales ?
