PS5 Game Boost: How does it work?

PS5 Game Boost uses the extra power available in Sony's next-gen console to boost the performance of backward compatible PS4 software. When enabled, certain titles will see enhancements based on their schedule. For example, if a game has an unlocked framerate with a theoretical cap of 60fps on the PS4 Pro, it can fluctuate between 40fps and 60fps. With the hardware available in the PS5, however, that same title would provide a 60fps lock on the latest PlayStation system.



It is important to note that you will only see improvements based on how the game is programmed. If a title has a 30fps cap, the only benefit you'll see on PS5 is that it will never drop below 30fps; it would need to be corrected to go higher. The same goes for resolution; some games use scalers that change the resolution based on what's happening on the screen. In these cases, the PS5 will most often approach the title's theoretical maximum – but only if it's programmed that way to begin with.



Developers can patch their existing software to take better advantage of PS5 Game Boost, such as unlocking frame rates and resolutions. In this article, we've compiled a list of all the major PS4 game improvements made possible by PS5 Game Boost.
