The same effects and such that the E3 footage used was in the game, but ubisoft turned it off AND made the pc version actively run worse. I'm guessing so the "next gen" consoles wouldn't look so bad and console gamers wouldn't complain, but to actively make the game look and run worse so to not hurt the feelings of console gamers is just wrong I think.
Ubisoft is trying to be worse than EA I swear...
