The PlayStation 5 and PlayStation 5 Digital Edition come with a Boost Mode, which is also known as Game Boost. To see how you can potentially enable and disable this feature, you can take a look at this article from Seeking Tech.
What is the PS5 Boost Mode?
The Boost Mode, or Game Boost Mode, of the PS5 is designed to enhance backwards compatible PlayStation 4 games by using the extra processing power of the newer console.
If a PS4 videogame has a target frame rate, such as 30 frames per second or 60 frames per second, then Game Boost will most likely make sure that it hits 30 fps or 60 fps more often than not.
If a PS4 game has a dynamic resolution scaling, then this enhancing mode will make sure that the game will display at its maximum display resolution more often than not.
How to turn on Boost Mode on PS5
Unlike the PlayStation 4 Pro where you have the option to enabled or disabled Boost Mode, the enhancement mode is automatically enabled on the PlayStation 5 and PlayStation 5 Digital Edition.
For the vast majority of PS4 games running on the new consoles, you will get a frame rate boost, resolution boost or both.
Keep in mind that there are some PlayStation 4 software titles that have multiple visual modes, with one most likely catering to better graphics and the other for better frame rate performance. To maximize frame rates, you need to select the frame rate mode from the in-game menu. To get the sharpest image quality, you need to select the resolution priority mode.
There are also some PlayStation 4 games that have been updated with a PS5-exclusive boost mode where you will get both frame rate and resolution enhancements. These games include Days Gone, Ghost of Tsushima, God of War, Ratchet and Clank as well as The Last of Us Part II.
There are also other PS4 titles where you can upgrade, either for free or by paying a fee, to the PS5 version.
How to turn off Boost Mode on PS5
Since Boost Mode is automatically enabled on the PlayStation 5 and PlayStation 5 Digital Edition system, there isn’t way you can turn off this feature.
If you have the disc version of the PS4 game that don’t have any visual customization mode until it was update via a patch, then you can try playing the game on your PlayStation 5 console offline. While the unpatched game will still most likely get a boost, it won’t be able to take advantage of any frame rate or resolution modes that were added to the patched version.
Otherwise, if you don’t want to play a boosted version of a PlayStation 4 game, you will either need to play the game on a PS4 console or a PS4 Pro console with Boost Mode disabled.
