I don't know if I am the only experiencing this problem, but I decided to voice it. My game became unplayable after patch 5. My screen freezes every several minutes. Every one of those freezes lasts a couple of seconds. And it happens no matter I do. I experience it during - animations, dialogues, sneaking. Also, on two occasions the game froze permanently, and I had to close it both times. I wasn't even able to finish the prologue. This is my 4th play through because I did a play through on every patch and this is the first time the game doesn't want to cooperate.
