I’ve only had a brief test this morning but I never noticed any performance improvements. I’d have expected it to be documented in the change log if it had those improvements mind.
Yes and no. Depends on the developer. I don’t have a lot of Square Enix developer knowledge so I wouldn’t know if they put in surprise performance changes. Lots of devs do.
