Is full backwards compatibility coming to PS5? This new patent suggests so



Sony may finally have a solution to go head-to-head with Microsoft’s popular Xbox Game Pass, as PlayStation architect Mark Cerny sheds new light on PS5’s backwards compatibility plans.

A new patent named “Backward Compatibility Through Use Of Spoof Clock and Fine Grain Frequency Control” introduces the method of running an application at a different clock frequency “when the application is designed for a different version of the system.” A second clock frequency would synchronize operation of the processor of the current version of the system. In other words, PS3, PS2, and PS1 would be able to run seamlessly on PS4 and PS5. 

Spotted by @shaunmcilroy (via PSU), the patent has been credited to Cerny and David Simpson. The solution is expected to be software-based, albeit a better one compared to PlayStation’s current method of playing previous titles: PS Now. In fact, you can check how PS5 backward compatibility failed Laptop Mag’s Mohammad Tabari and how it was easier to use a dusty PS3 to play Ratchet & Clank.
