Which PC exclusive AAA games are you referring to? Which PC game, developed for the PC, has better graphics than TLOU2 or Demon's Souls?
Games like Marbles and Star Citizen look better, even in the eyes of any average Joe. Others like Minecraft or Quake RTX have better lighting than anything on consoles. Games like Arma 3, TW Warhammer, Beam NG drive, Teardown amongst others have features that make them more technically impressive, and they can be seen even if they are the result of superior physics. Then of course you have plenty of multiplatform games which look better than exclusives, such as Cyberpunk 2077, MS flight simulator 2020, Control, RDR2 or Metro Exodus.
I’m not denying that games like TLOU 2 and Demon Souls look good, but they are good games making heavy compromises due to the hardware they are running on. Lighting, first and foremost, is several steps below some of the PC games named above, you can also add resolution, fps, reflections, shadows, ambient occlusion, tessellation, LODs, procedural animations, volumetric fog and anything you can think of; they can always go higher on PC (even beyond vanilla options in many instances) and they affect the way a game looks. Anyway, even if somebody can’t spot differences, they’re still there and while not subjectively important for the person, they will always be significant in a number-crunching (quantifiable) way.
I’m not sure why certain people seem to believe some first party developers are geniuses while other developers can’t put two and two together; you can’t match what any talented (or up-to-date with current techniques) developer can do with a 3090 by using a 2060, magic doesn’t exist and in a era where games consist of thousands of line of code and APIs are efficient, optimization stands for compromises.
PC is in a league of its own and even first party games benefit from running on better hardware, that’s just the way it is.
