Uh...maybe easier if you play with a mouse and keyboard for such (UI systems) complex game?
Surely the powerhouse of a PS5 can do it? Or is it a Larian problem?
Its like trying to ride your sedan car with 4x4 truck tiers. Sure it can be done with some tweaking. Sure you'll get to your destination. But is it really worth the effort ?
Larian doesn't support KBM on PS5 and the only info we have is "Its too difficult to implement" from before release, so I don't have much hope about it.
