According to a report from Digital Spy on Saturday, "Watch Dogs" senior producer Dominic Guay talked about the importance of the PS4's memory and that if it wasn't as fast, it would make a big difference in the game.
"If you have a lot of memory but it's very, very slow, it's not as useful
"[PS4 has] very fast memory. I mean, 8GB of RAM. What that means in short is that there's a lot less limit on your creators, on our artists, and details and the diversity of what they can create.
"For an open world game like 'Watch Dogs' it also means something very important because if you have a game that happens in a small corridor, yeah, you can put a lot of detail in the corridor.
"Our game's in an open city where you can get into a very fast sports car and drive at 150 miles an hour, so typically what happens then is that you'll trade off scale or density but we don't want to do that, because in 'Watch Dogs' you can hack anything, and if you end up in a street where there's nothing, then the game's truth kind of falls down.
"We want to have a lot of density in our city, a lot of people that you can spy into, and lots of things you can do. So that's density while keeping scale, and definitely memory helps a lot with that," Guay said.
