Absolutely dire performance on PS5

I'm watching my partner play on their PS5, and the performance is the worst thing I've ever seen.

Game stuttering for .5-1 second each time it needs to load a new ability or enemy texture.
UI textures taking 3-5 seconds to load, so when you zone in all the boxes are just blurs.
Load times in the 30+ seconds.
I just tried to help them through Merc Lab, and the game was freezing/stuttering each time Izaro did a new move, resulting in constant deaths while the game is frozen.

I don't know how this was approved, honestly. It's a shame, as they love PoE 2, and I wanted them to get as excited as me for PoE, but can't do that when it's almost unplayable.

Any timeline for fix??

actually seems a lot better on PS5 with the patch/version that came out last night.
