happening to me as well...
after updating to patch 3 every move, dialouge , etc get very laggy and have delay for 1/2 second , even opening menu by ESC is delayed don't know why..
when i walk often my characters is flying instead of running like usual , graphic setting is already the same as before patch 3
i tried lowering all graphic setting yet still get same result of laggy game and unplayable ( very not comfortable of playing )
anyone know what solution for this? until now Larian haven't give any update again regarding this
very frustating
