After downloading patch 3, I've noticed significant lag in certain behaviors. There is a noticeable delay between when you initiate a conversation and when it actually starts. Spell animation is taking a few seconds to occur after you cast a spell. Companions in your party delay following you (at least graphically). The delays are long enough that it really hampers the experience. It would be great if you could look into this and figure out/fix the cause.
I experience it as well on PS5 , game was working perfectly fine before.
Now when any action is taken e.g firebolt is thrown there is a sound of action then after few seconds animation of character throwing it with his hand appears and few seconds after firebolt itself appears.
I tried to restart the game and it works fine there. But when I load any of my main plaithrough saves the issue appears.
It breaks game experience badly, I am in the end of act one and I would really like to be able to finish it, don't want to start new game, spend all of this time and be scared of this happening again.
I hope it gets fixed with a patch soon and my saved game works good again.
