I think one problem is many console ports are having to make bizarre engine choices to hit steady frame rates on PS5, like Star Wars Outlaws has dynamic rendering with FSR AA which means its rendering at 720p apparently sometimes and then upscaling to 4k, but no matter how good your AA or DLSS or whatever is, end of the day you are still rendering visuals at 720p which sucks.
So a PS5 Pro may hit a steady 60 fps in that case but what does it matter, the engine is rendering at 720p first so no matter what post processing horsepower you apply, its still kind of a shitty foundation. Now Outlaws is hopefully an outlier case because its Ubisoft and they suck balls but I am curious if stuff like Stellar Blade or Black Myth Wukong will run better on a PS5 Pro or not.
still, apparently every game built with the sony SDK after like august 2024 will have the PS5 Pro flags built in so hopefully its not extra work for the dev to make things run better for newer games.
I finished the Callisto Protocol recently and that game has a weird option where ps4 and ps5 are cross save, so after every trophy on PS5 version I'd load the latest autosave on PS4, get the trophy, and that way with an extra ~2 hours of effort I got two platinum trophies. Stupid as fuck and a complete waste of time? Yup, but the interesting thing was seeing the very different way the PS4 and PS5 versions of the game ran.
I could really, really feel the difference in input lag and visual FPS on the ps4 version, it just felt a little bit slower and laggier and it was instantly noticable I was playing a "less" version. I'm sure the PC version is even better, and I probably should try it out since I have a 3080ti and own the game on EGS (free ~2 weeks ago).
