I imagine you haven't seen the best of 4K gaming on the best 4K display yet. It looks pretty next gen to me. Assassins creed is killer. And if I had a 4Pro I'd feel that way about HZD i'm sure.
I have a PS4 Pro connected to a Samsung KS8000 and played checkerboarding games like Horizon Zero: Dawn, Rise of the Tomb Raider or Witcher 3. Image quality like that is incredible and imo completely sufficient for next-gen. If I had the choice between playing those games at 2160c/60fps or at 2160p/30fps, I would always choose the former. I recently played The Last of Us: Remastered on my Pro, and it was such an incredible experience at 1800p/60fps. The high framerate really helped to bring immersion to the next level, really amazing.
50% less resources and output similar quality to native is a touch too aggressive. Checkerboarding does not absolve the renderer of all loads by the same amount. And not all checkerboard algorithms are for both axis, sometimes we just see checkerboarding along the x or the y. Which means it's saving up to 25% less compute in that case.
With checkerboarding, the GPU needs to render 50% less pixels compared to 2160p. I'm not a graphics programmer, but from what I have heard the only obstacle here could be memory bandwidth, because they might need a 4K framebuffer compared to resolutions like 1440+p with a similar pixel amount. And the games I listed above are using CB for both axes.
Regardless we've seen checkerboard solutions on PS4 Pro 4K vs X1X 4K native, and X1X is still running higher settings that 4Pro. So that should be enough to debunk that argument because X1X is clearly no where close to 2x the GPU for 4Pro.
Which titles are those? Genuinely curious, can't think of any at the moment. Also not sure what you are arguing - are you saying that devs don't need twice the amount of GPU power to render a 2160c game at 2160p?
You'll still get 60 fps games. I mean, no one is saying next gen is going to be jaguar again. But lets not get carried away on the CPU side of things. If developers want to focus on gameplay, they'll focus on 60fps. If they want to focus on story and immersion, you're going to see 30fps, better graphics and sound.
60fps is a lot more immersive than 30fps ever can be. All my 60fps single-player game experiences have been among the most memorable experiences ever.
I really think next-gen could be the generation were we might see more 60fps games than ever, thanks to exciting tech like Ryzen at 7nm, VR and ever-increasing dev budgets.
I also think if Sony will announce a 60fps standard (or a mandatory 60fps option) for next-gen at their conference, this would be the ultimate mic-drop moment, which would probably break the internet. I can't think of a more impactful announcement they could make, people would go completely crazy. Something like this will also really help to distinguish next-gen from mid-gen consoles, because we won't just see cross-gen games with higher res, but a completely improved gameplay experience.
