I don't think that's really a metric to compare against. PC still has Crysis, which would still to this day, melt a PS4P itself.
I myself have been playing Hunt Showdown for some months, and to me it looks visually stunning, while also making good use of directive sound.
You'd have to take up that discussion with Pemalite, because he knows that bit better when it comes to optimisation than a few console only folks here (who take in a few articles and some jargon like "to the metal".
Next gen systems will try to run at what they try to advertise, but that doesn't always mean that they'll stick to it 100% of the time (Hence why I find some hypocrisy in that beauty you speak of, because if I see it on the tin can, it better be doing that 100% throughout the generation).
As for myself, I wish to see improvements made to AI, as well as 4kres textures, and not just those we find on the NPC's/Weapons.
Well like I said, I think pc gaming is great. However, having the latest $2000 GPU will only get you crazy fps and native 4k with games that you can play on the ps4. Kinda like the ps3 remasters we see on the ps4 pro. Sure it's nice but there's a big difference between lets say a TLOU remaster in 4k and TLOU 2 in 1080p.
That is what I mean with coding to the metal. Games are designed from the ground up to run at a locked 30fps 1080p and they can squeeze every bit of performance out of the hardware to make the games look as good as possible. Crysis was probably the last game that really pushed the latest pc hardware of it's time to its limit and it was unlike anything on consoles. But unfortunately the time that pc's were pushing the graphics is behind us. Now we kinda have to wait for the ps5 to come out with games optimized for the latest gpu's to see what they are really capable of.
