When are people going to learn that you cannot make a blanket statement like that in a vacuum. Performance (resolution and fps) is a function of
workload. So guess what, your RTX 3090
can run nearly all games at native 4K 60fps...if YOU TURN THE SETTINGs DOWN!
What your statement is really saying is that you can't run every game at native 4K 60fps with "maximum" settings. Yeah that's fine for you PC elitist crowd that would never imagine playing a game at anything lower than
MAX settings. But then you compare to the consoles as if it were ever an aspiration for any sane developer to develop a console game running at maximum PC settings (total waste of resources). In fact, most do not and they run at some mix of settings that work best in balancing IQ and performance for the given hardware. Yeah, the proper way to develop a game.
So moral of the story: it's entirely plausible that the game struggling at 4K native ~50fps and
max settings on your 3090 could run at native 4K 60fps with an optimized mix of lower settings on PS5/XSX....and you probably wouldn't even notice the difference unless viewing side by side comparisons.
