What? There was no "catching up". PC is and has always run the games better. Consoles aren't running 4k 60fps with ray tracing either. It's simple "running ray tracing". To do it, they are running much lower resolution, less settings, and getting 30fps. There is no catching up here, nor was there ever in the PS3/360 era. Affordability is a completely different topic to either the platform can run it or it can't.
In some ways you are right now I look back at my comments, to me though there were exceptions mostly on PS3
The last of us, Killzone 3, Metal gear solid 4, Uncharted 3 and I even remember GTA V before it later got ported to PC looking and performing amazingly well, I also could afford a good PC then so I could make some comparisons with PC games of that era and I was impressed at the time.
(I know some of these are exclusives and they're never was a PC version, but Killzone 3 and last of us at the time of there release I couldn't see a PC game that compared to them graphically)
(Some other titles did look worse than PC though I wont deny that)
For me affordability is where I am now I couldn't afford a good PC to play games with all the settings on high or ultra anymore
(So a series X or PS5 is tempting as the performance is impressive for the money spent)
So I guess 60fps 4K with ray-tracing on console isn't going to be easy or possible on all games, so if it brings game performance down to 30fps maybe games on PS5 series S/X will have to run on these lower settings and other compromises and not have ray-tracing to keep performance high.
It goes back to ray-tracing is too high a requirement it might not be used all the time, but programmers are very clever people I see some jaw dropping stuff appearing later on, who knows they might even find a trick to get RT at 4K 60fps working with some other techniques.
