Game looks amazing and I think they made all the right decisions for this game's visual look and style. Based on the analysis, they found an Internal resolution of 1080p, but then the dev uses temporal reconstruction to bring it to 1440p, and then from there they checkerboard to get it up to 4K. The resolution matters much less compared to the final result on screen, which is damn impressive no matter how you slice it.
I don't have a single criticism of the game's visual appearance, and what was pointed out are things I wouldn't have noticed anyway. Even if by some chance I did, I wouldn't view them as flaws if that makes sense. I'm an oldschool gamer who recognized tricks or visual behaviors based of the various techniques used as important parts of a game's visual identity. Take, for example, the pre-rendered backgrounds in old ps1 final fantasy titles. I don't care how they did it, but it looked great. The same holds true here for me. You're on a weird and creepy ass planet with creatures with all kinds of tentacle like creatures coming at you. Who is going to stop to be like "hmm, that swaying grass in the fog there doesn't quite look 4K or very high res?" DF because of what they do must, but I as a gamer will not. I see that blur and would probably see it as an intentional visual element to play into the game's style and mood. Kinda like when you open doors you see ever so slightly see dust or fog spreading aside as if the door hadn't been opened in forever, or it's some kind of pressure seal.
Every decision works for the game's atmosphere. The game is an amazing technical showpiece for the PS5, so there's no wrong or inferior way to achieve what they achieved is how I see it. They got it done, and the results are fantastic. The primary reason these analysis exist should be to better educate us on how games did what they did, but more often than not they're for console wars and trolling. Everything they learned from this release about the console can now be applied to any future work they do, such as a sequel if it gets approved, and I'd be surprised if it doesn't. Even a spiritual successor of sorts with the same elements can work wonders. Can you guys imagine these dudes making an open world RPG that plays the way this one does? Either way, Housemarque now joins the big boys because that's what Returnal represents.
