PS4 Tales of Arise Backward Compatibility Performance on PS5

Recently I finally got myself a PS5 but I found out that Tales of Arise PS4 save file isn't compatible with the PS5 version. So I was wondering how does the PS4 version perform on the PS5? I really don't want to restart my first playthrough at the moment since I've already put in quite the number of hours before I got my PS5. Couldn't find any videos or details for PS4 Arise BC on PS5.
