Again: this is a PS4 app, not a PS5 one
PS4 apps doesnt use the whole PS5 hardware, so performance is limited.
It has nothing to do with bad optimization, so please stop spreading misinformation
Considering that this has limited compatibility with the PS5, it runs great, with smooth framerate and better resolution
+ Better draw distance, something that even Sony didnt implement when they made TLOU 2, GOW and GOT PS5 aware apps
