We will only get a big leap again when AR or VR become a thing, or at least is the only leap I see on the horizon

The last big leap on gaming was the advent of internet multiplayer. This dramatically changed how people make and play games, which is not even a console gaming innovation as it started on PCs

Graphic advance is useless if it doesn't change gaming experience, so far new generation games looks like prettier versions of PS4/XBONE games with shorter loading times

First, history has put into doubt that there can be a decent convo with someone as one-sided as you are when it comes to PlayStation.

Second: https://insomniac.games/game/ratchet-and-clank-ps4/

Ratchet & Clank blasts onto PlayStation 4 for the first time, with a new game based on elements from the original Ratchet & Clank(PS2). Ratchet & Clank (PS4) re-imagines the characters’ origin stories and modernizes the original gameplay. Featuring all-new boss fights, several new planets, new flight sequences, and much more – with completely new visuals constructed to take advantage of the power of the PS4.

Produced alongside the major motion picture coming to theatres in 2016, Ratchet & Clank (PS4) is a curated experience borrowing from the spirit of the classic PS2 titles while infusing some of the best elements from the Ratchet & Clank Future games. Return to the Solana Galaxy and find all your favorite characters: Ratchet, Clank, Captain Qwark and super villain Chairman Drek, as well as many new ones in this third-person action-adventure platformer. Explore exotic planets, collect out-of-this-world weapons, and help Ratchet and Clank save the galaxy for the first time, again.

Third: Take Halo, Uncharted 1, Ridge Racer, etc, and compare them with their late gen counterparts or games of the same type. The last two gens showed an even bigger gap due to having much more titles being cross-gen, meaning they were produced using engines that were tailor-made to exploit the prior generation rather than the new one. You will see this again a lot with the games releasing in the first year of gen 9.

Lastly: I wasn’t disagreeing with anyone who points out the biggest [felt] jump was when consoles went from 2D to polygonal graphics. The only thing I addressed and put into question was your comparison that focused on Ratchet, a cartoon character, that you used to somehow illustrate a lack of a big jump between both consoles.

Firstly: History shows (YOU) cannot maintain a decent conversation since you are the aggressor in the reply, stating Trolling and calling someone a dumbass is enough proof  right their. You want to go by history, i wouldn't be talking.

Second: This isn't about Playstation, get off your high horse. It was an example. The fact you took it as an attempt of trolling proves your unstable manner in the conversation. The fact you had to go on calling someone a dumbass shortly afterwards, shows your intellect in a debate over a petty misuse of a subtitle. How about just reply with a civil answer next time. Might make conversations with you more serious.

Third: I am not denying the improvements from generation to generation. If you actually paid attention to the examples i used, instead of trying to flame someone, you would see my point. What we have currently seen from 9th gen isn't exactly impossible to run on 8th gen. What we saw from Mario 64 cannot be replicated on the SNES. That's how much of a leap the jump from 2D to 3D was.

Lastly: Please read into someones post before jumping straight to generalizing and shaming.

Clearly in denial about what I pointed out about your bias, which is that you have a known history of downplaying PS in favour of MS and Nintendo. That’s a widespread known fact and makes it difficult to take your stance on anything PS related seriously. Regardless of what you’re trying to convey, what you project will more often than not be interpreted as negative because of that history. Contrast this with my history of [clearly] defending PS but without feeling the need to downplay the other brands in the topics I take a part in... So, if in this here case, this wasn’t your intention, I apologize for my mention of the word dumbass. And sure, I have a history of not offering much patience to most people around here.

Now, visibly, you got stuck on the first part of my last comment and couldn’t let it go for the remainder of your comment. But in the end, your whole comment and especially your third paragraph is display enough that you shouldn’t have written your fourth point.

It did take a while for PS3 and 360 to really show what they could do, maybe the same will apply for PS5 and Xbox Series. Stuff like Hellblade II and the next God of War might end up being this coming generation's Gears of War/Uncharted moment.

On the other hand, other systems like, say, PS4, Xbone, Gamecube, etc showed their muscle from the get go and didn't massively improve over their best looking early games. Remains to be seen which PS5/XS will be, but given their tech is still fairly new I'm gonna be optimistic.

I’d argue that the step from Uncharted 4 (even though it’s still a very good looking game) to The Last of Us 2, or even God of War is quite big. And console launch games like Assassin’s Creed IV, Killzone: ShadowFall, Call of Duty: Ghosts look miles behind similar games like Horizon Zero Dawn, Spider-Man, Red Dead Redemption 2, Titanfall 2 or Doom Eternal.

Don't get me wrong, there was still definitely noticeable and significant improvement, I just wouldn't call anything on PS4 a "massive" improvement over Shadowfall which I think still looks great today despite being a launch title. (Same with Ryse on Xbone)

They still look good, thanks in huge part to their art design, but both are plagued with technical issues, low res assets/rendering, and the likes. Aspects that aren’t found or at least not nearly as prevalent in late gen releases.

Sure enough, we’re constantly going towards that fabled point of diminishing-return, but you and I are both among those who notice the finer aspects of graphics building blocks, so I am sure you’ll notice how big of a gap it is between the two generations when games that exploit all those extra ressources finally come out. 

I think with the PS4 part of it was that it was using tech that was basically proven and off the shelf, so while software techniques did evolve over the generation, it was quite easy to exploit the hardware's potential right from the start. PS5/XS are using tech that is comparatively newer and less proven, which does suggest we'll see big improvements over the early games shown so far.

The likes of Naughty Dog and Santa Monica reliably work miracles with the hardware they're given, and Ninja Theory managed to make Hellblade 1 look  amazing on current gen, so once those guys start putting out next gen exclusives we should see what the hardware can really do.
