Hmm, I haven’t seen but I’m going off the animation we already have in the game which can be pretty wonky. Of course there could be vast improvements between now and full release, and I very much hope there are. But I don’t find what we’ve seen from BG3 so far promising in this respect.
I've seen various cutscenes go from having wonky/no animation to a patch that makes them look very natural. Some of Kagha's scenes at various points had no lip syncing at all off the top of my head. I think it's fair to say that a lot of the worse scenes are just not yet complete.
