I bought and downloaded PA yesterday. I started playing it and it was working fine, then I was attacked and the UI completely lagged out and stopped moving and working, I am pretty sure my computer is powerful enough to run the game, but I don't understand what is wrong though. My system is: CPU: FX-8350 GPU: GTX 760 Hard Drives:120GB Samsung 840 Evo(OS/Drivers) and 1tb mass storage for games. If you can help me with this problem I would be very greatful. Thanks in advance.
