Sony is giving developers further access to the ‘s CPU resources, potentially paving the way for enhanced performance in future games, if the latest documentation from a middleware company is to be believed.

Differences between PS4 and Xbox One resolution and frame-rates have been less pronounced in 2015, with often no meaningful difference between both systems, as some examples below demonstrate:

  • Battlefield Hardline – PS4 900p, Xbox One 720p
  • Star Wars Battlefront – PS4 900p, Xbox One 720p
  • Batman Arkham Knight – PS4 1080p, Xbox One 900p
  • Metal Gear Solid 5 – PS4 1080p, Xbox One 900p
  • Call of Duty: Black Ops 3 – PS4 1080p, Xbox One 1080p-900p (dynamic)
  • Project CARS – PS4 1080p, Xbox One 900p
  • Evolve – PS4 1080p, Xbox One 900p

Whether the enhanced CPU access on PS4 could result in a widening of that gap is a matter for debate.
