Sometimes we do. Sometimes we dont. CD Project admitted to changing the entire renderer in Witcher 3 to get the game running on base consoles. Epic admitted to taking out realtime GI support from UE4 after realizing consoles were too weak to do it. Remedy and Avatar devs both publicly talked about Series S's memory constraints but did not use it as an excuse to hold back their games.
We are playing Crimson Desert right now, and despite its issues its doing some insane things other devs havent even bothered with this gen. So in essence we can compare two games, two engines, and two different design methodologies. Were kojiPro or Sucker Punch held back by the handheld PS6 or just their own ambition? Something BOTH developers admitted to. Risk Averse and We didnt even bother were answers from both companies' CTOs.
Maybe Sony told their devs in 2018 to target 1440p 60 fps when Demon Souls and Ratchet first began development because they were planning a 5 tflops handheld. It would make sense in a way seeing as how virtually ever other dev targeted the full 10 tflops. But 2018? or Even 2020 when development on Ghosts 2 and DS2 first started is too early. I doubt there were even conversations around a PS6 handheld back then. let alone mandates for developers. if anything, what we do know is when the mandates arrived which was late last year when devs started pushing out patches to have the games running in low power mode. So 2025.
You can scale graphics better than ever nowadays. Even PS5 Spiderman remakes, DLCs and sequels reduce the traffic and NPC density in performance modes. They are able to remove ray tracing effects or reduce RT vram usage by reducing the ray traced objects in the BVH. They turn off hair strands, reduce foliage to last gen levels, remove fancy water simulations from Series S versions. We are playing path traced versions of Re9, Pragmata and James Bond over the next couple of months. Path tracing is very vram heavy. They straight up skipped ray tracing on the Series S, and even base PS5 and XSX. RT only shipped on PS5 pro. The same thing will happen next gen. GTA6 will blow away everyone in ways Crimson Desert can only dream of, but RTGI, hair physics, and water simulations will likely be removed from Series S, PS6 handheld and Switch 2 versions.
