Just made an account here to confirm the same issue. Wife and I played on PS5 for about 12-15 hours and just got a little ways into the Underdark in Act 1. There are a solid 2 seconds of hitching/lag every single time we switch characters. Essentially unplayable in split-screen. It's was also occurring every time I cast Minor Illusion. We had to stop playing last night due to this issue. Larian please fix!
