Definitely the opposite there for me. I've played and beat it fairly easily on PS4 Pro, which used "30 fps" as more of a loose guideline. At least here the 30 fps is almost completely stable (like the DF video says though, if you have effects going off very close to the camera it will briefly dip to 28 or 29 fps for a second). If 60 fps was all I cared about I'd just play it on my PC which would do a hell of a lot better job and would have ultrawide, mouse aim, etc. It's actually really easy to notice the RT effects even in the middle of a hectic fight, because there's no weird halo around Jessie--or much worse, the way shadows and reflections completely break when you're getting ready to throw a large object. If you don't know what I'm talking about, it's at about 9:15 in the first DF video I linked to. One of those things where once you notice it you can't not see it anymore and it's very distracting.
Kind of disappointed they didn't add in HDR though. It was weird that the old version didn't have it that late in the generation, and really weird that if they were going to take the time to redo everything with raytracing in mind that they didn't set up HDR as well.
Also, DualSense haptic stuff is fucking retarded. Screwing with the triggers doesn't actually make them feel like pulling a real trigger, it's just annoying and makes you shoot slower than you should be able to. Having the controller vibrate slightly every time you take a step is pretty damn irritating too. I played the game up to the first control point on both consoles, definitely sticking with the XSX version. Can't say I'd recommend it to people who don't already own it on Xbox seeing as the PS5 version is "free" and MS let 505 get away with just the basic bitch version on Game Pass, but the two consoles are basically identical if you're playing with RT on. From what DF said, XSX performance mode needs a patch to fix some weird fps drops that don't happen on the PS5, so if you're going for 60 fps mode stick with PS5 (ideally PC) for now.
