When it was announced that Naughty Dog would be bringing The Last Of Us to PlayStation 4 via The Last Of Us: Remastered, many were skeptical about just how much effort they would be putting into this remaster. Well, judging from this interview with Edge, they went through a hell of a lot of trouble to make this thing work.

Naughty Dog  creative director Neil Druckmann said the following:

“We expected it to be hell, and it was hell,” he said. “Just getting an image onscreen, even an inferior one with the shadows broken, lighting broken and with it crashing every 30 seconds … that took a long time. These engineers are some of the best in the industry and they optimized the game so much for the PS3’s SPUs specifically. It was optimized on a binary level, but after shifting those things over, you have to go back to the high level, make sure the systems are intact, and optimize it again.

Basically, every single thing about this game has been re-done. Which makes me very optimistic about the finished product we will be dealing with when it releases on PlayStation 4 later this year.
