What is add-one manager? I see nothing different to my current game after the most recent update. Does it just run in the background or should it require input? If so, how?
It just runs as part of the core game. You don’t need to do anything. It basically means that the game only loads the bits it needs and therefore gets around the Sony imposed 64gb limit for DLC.
It also improves upon the memory footprint of the game, which results in better stability & performance.
