Just to be clear.... all according to whoever this guy is; 9 months ago the game was running at 9fps, then after optimizing (which mind you is what every dev does when making a game) they got it to 720p/30fps, then they just got it to 900p/30fps a few weeks ago. But somehow thats all the optimization they can do and the PS4 can't handle running better.
So basically the PS4 is maxed out at the same point the XB1 was able to reach?
Sigh... Ubisoft. Please just shut up.
