Double Agent is optimized for 360 architecture which is why it doesn't run as great on the ps3. It's like on a PC running Oblivion with an ATI or Nvidia card. The game will work with either card but each card will run the game differently in terms of framerate and image quality. Take Devil May Cry which was a PS exclusive until recently. More than likely it will run better on the ps3 than the 360. Everyone is quick to blame stuff on lazy developers but the truth is some games will play better on 360 and some will play better on ps3. This isnt the first or the last time this will happen this generation so people just need to accept it...
