The patch notes are massive & I tried to avoid spoilers: did they add a merged split screen for combat as well to reduce issues and/or dynamic while travelling around?
No, I don't think they did, at least based on patch notes. Though I didn't see mention of the split-screen delay issue being fixed either. Not a single acknowledgement that it was ever an issue. I mean it was bad enough that they probably didn't want to draw attention to it.
Well, probably because what caused the issue was lack of optimization on many things which wasn't exclusive to PS5? There are many items under the PERFORMANCE AND OPTIMISATION section that seems related. Such as "Optimised turn order calculations in combat". The game is basically running turns every 6 seconds and even when you aren't in combat is calculating A LOT of things. We all just happen to be using the same processor.
In addition, in my perception I don't think merged split screen will be added so soon because on how they implemented a few things that are different from Divinity 2. In Divinity 2 couch co-op, during combat you would never be able to have two characters acting/moving at the same time (and I don't know why they went for this, considering how the AI bugs when they are trying to go to/pass through the same place and that you can't take turns at the same time during 5ed).
