Sony revealed in a post today that the PS5 will be backward compatible with "the overwhelming majority" of PS4 games; meaning over 4000 titles. Some of these will benefit from the PS5's Game Boost feature which could improve the original game with higher or smoother frame rate. The company also confirmed the compatibility of the PlayStation VR headset and PS VR games which will require, in addition to the headset, a PS camera (sold separately from PS5 console) and a PS camera adaptor (no purchase required).
However, the console maker also mentioned limitations regarding this backward compatibility. For one, the post mentions that some functionalities available on the PS4 might not be available on the PS5. Additionally, Sony writes that some PS4 games "may exhibit errors or unexpected behavior when played on PS5 consoles". The company did not clarify which games will be affected by those issues nor what these issues are specifically.
Moreover, Sony did list 10 games which will only be playable on the PS4 and not on its next-gen console. These games will feature a ‘Playable on: PS4 only’ tag on the PlayStation Store. You can find a list of those PS4-only games below:
- Afro Samurai 2 Revenge of Kuma Volume One
- TT Isle of Man - Ride on the Edge 2
- Just Deal With It!
- Shadow Complex Remastered
- Robinson: The Journey
- We Sing
