Summary

  • PS4 Image Enhancement (IE) is designed to improve the quality of PlayStation 4 titles when they are played on the PlayStation 5, using AI to upscale the games to 4K
  • It does not work on all PS4 titles, with Sinister Vanguard citing Rocksteady’s Batman Arkham Knight as one game that doesn’t support the feature
  • While PlayStation 5’s Compatability feature simply allows PS4 titles to run on the console at their original visual quality, PS4 Image Enhancement takes these games and improves them, rendering a 4K image that is then fed to the user’s TV, according to Digital Foundry’s testing of the feature
  • It is reckoned that, with this feature switched on, playing on a 4K TV will give gamers the option of seeing PS4 titles running at their absolute best, even though the underlying rendering pipeline will still be that of a PS4 game.
