Most PlayStation 4 games can be played on PlayStation 5, which means a PS4 library can remain useful long after moving to newer hardware. Sony says the overwhelming majority of the more than 4,000 PS4 games are compatible, but that does not mean every game or feature works identically.
What does PS4 backward compatibility mean?
Backward compatibility allows a supported PS4 game to run on a PS5 console. The game remains the PS4 version unless there is a separate native PS5 version or an upgrade. This distinction matters because a PS4 game running on newer hardware does not automatically receive every feature found in a dedicated PS5 release.
What is PS5 Game Boost?
Sony says select supported PS4 titles may benefit from Game Boost, potentially producing higher or smoother frame rates. It is not an across-the-board promise of 60 fps or a specific resolution. Whether the change is noticeable depends on the game and how its performance limits were designed.
Are physical PS4 discs supported?
Disc-based games require compatible hardware with a disc drive. A digital-only console cannot accept a PS4 disc. Players should check the edition of their PS5 before purchasing a physical PS4 game with the expectation of playing it there.
Can features behave differently?
Yes. Sony cautions that some PS4 features may be absent when a game runs on PS5, and some games may encounter errors or unexpected behavior. Extra hardware requirements also matter for certain PlayStation VR experiences. The safest approach is to check official support information and test existing games before spending money on add-ons.
What about saves and upgrades?
Save transfer and upgrades depend on the title and its supported methods. Moving between PS4 and PS5 versions may involve a different save-transfer process than continuing with the backward-compatible PS4 edition. Check the developer’s guidance before deleting an existing installation or save.
Should you keep your PS4 games?
For players with an existing library, backward compatibility preserves access to many older experiences. Before upgrading hardware, identify the games you care about most, check whether their specific releases are supported and decide whether a native PS5 upgrade is worth the additional cost.
