Just joining in to confirm that couch co-op split screen is unplayable. My husband and I are devastated... We own the Deluxe edition on PS5 only, we bought the game specifically for PS5 so we could play together. And we can't, because the freezing is horrible, and we're even playing in Performance mode. We've already submitted a bug report, and I posted a separate thread on the subject. If it's about demanding visuals, we are ready and willing to have it reduced for the sake of performance. We love the story, the characters, the mechanics, but the persistent freezes suck out all the joy from our playthrough. We stopped near the end of Act 1 because we simply can't take it anymore.
