Came back from 2 week vacation and new patch 3 to find the game is next to unplayable.
Companions are rubber banding all over the place, when I take an attack or spell action it takes like 5-10 seconds to resolve during which time the characters are just standing there.
Picking up items or opening chests also laggs and is delayed. etc etc. Similar to someone else some animations just keep playing over and over (i.e. the guardian statues someone else mentioned.
It's great that new patches and fixes are introduced, but when they break existing games, that's not good since I, and I assume many others, don't want to restart a game everytime Larian releases a patch.
