At the NYC event, Sony’s selection of developers made it sound like making sure games support HDR wouldn’t require a lot of additional work. Al Hastings, chief technology officer of frequent Sony developer Insomniac Studios estimated that it was only taking one “person-month” (the amount of labor it’d take one person to do in one month or, say, two people to do in half a month) to get the PS4's Ratchet & Clank game to support HDR. Naughty Dog’s Christian Gyrling said it took roughly twice that for his studio to prep the PS4's The Last of Us and Uncharted 4 to also support HDR. The games will get small patches of 100MB or so to enable that functionality, mostly using existing assets from the games. Both men said that new games built from the ground up to support the Pro and the base PS4 might require a little more work, but not an extensive amount.
