I did my 1st playthrough before patch 4 and enjoyed it so much. It was a "good" playthrough with an elf bard. Act 3 was ok.

Now since I entered Act 3 on my 2nd playthrough with a drow Dark Urge it is really hard to play.
Companions are not following me, dialogues and fights take sometimes 3 mins to even start. :-(

It started after patch 4, unfortunately patch 5 brought no improvement for me at last.

I play on PC without mods.

Has someone the same problem? I am not having fun anymore, this is too much.
