The hardware is more than capable, and the visuals will only get better over time. But the above games and tech demo's use ICE technology which is provided amongst first parties and some second parties.
When it comes to the exclusives, you wont see visuals like these elsewhere, not because of the hardware, but because of how well ICE uses the hardware. 

Maybe from an aesthetic point of view..

So true!

Havent seen anything match Uncharted 4's level of detail. Not even on high end PC...

But then again no PC developers are putting that much effort into a single character. Drake looks near CGI in that small U4 clip! I was shocked when i heard it wasnt CGI.

This is why IGN split its best Graphics award into two categories: technology and art. Every other media outlet should do the same imo because art is subjective while graphics is based on facts (res, fps, polycounts, physics etc).

as a PC gamer, i've never seen anything look as good as Driveclub and The Order 1886


the issue here is that there are less and less PC high budget exclusives. companies who made those went multiplat with consoles, and even though their PC version were the best, it's still held back due to multiplat development. After Crysis back in 2007, PC graphics pretty much hit a stalemate. Only a few improvements, nothing compared to 2000-2007.

some smaller companies are able to make impressive graphics for their size but there's only so much a limited budget and small studio can do, so they don't really take advantage of the powerful PC hardware to its maximum capabilities.

I'd say that with a new gen of consoles there could be another jump in PC graphics but that seems unlikely, who's going to do it? Not Witcher 3. Not The Division. Star Citizen? I don't even want to talk about that game, that is going to be such a huge disappointment...bigger than X: Rebirth.

Almost makes me regret getting a new gaming PC in 2 years ago but not really cause there's still some exclusives i want to play; difference is that they aren't particularly demanding or great looking, like Beyond Earth.. and the best versions of Arkham Knight, etc. Still worth it, but not the same as before. Whereas before i upgraded components every 2 years, i don't plan on upgrading now until the next generation of consoles.

The graphics looks great, period. But when people say "I have NEVER seen something like U4, the game that will be out a year (or so) from now and that we dont have a gameplay footage" i have to call this out

Infamous Second Son: looks gorgeus, in pics, in motion, in everything. But when we take a closer look we see low-quiality reflections (in details), a not-that-good draw distance (in details again) as if they where using tricks to push it. (leaving aside the fps department) I will search for that image later

I DONT want to start a dick measurement between ps4 and PC. We need to acknowledge that these doesnt have "graphics", they have hardware that push graphics and it depends on each developer to make graphics great, not that great or average. Of course PC will always have more potential for this, as there is a new GPU every year or less but devs dont aim for that small porcentage of gamers

With that said, we shall only talk about how good it really looks when they´re out, whether its "in-engine" or "in-game" footage.
