Sony has recently released a PlayStation 4 firmware update, 4.5 beta. This is to test users prior to the launch to the wider user base.

Sony Releases New PS4 Update

Aside from several announced features like external HD support, Sony has also added a new feature just for PlayStation 4 Pro users. According to FanSided, the update was officially confirmed to include what is called "Boost" mode. 

According To Sony

Boost mode lets PlayStation 4 Pro run at a higher GPU and CPU clock speed in order to enhance gameplay on some PS4 games that were already released before the launch of the PS4 Pro.

Before the launch of the PlayStation 4 Pro, Mark Cerny, PS4, and PS4 Pro system architect were not very much keen on the idea of allowing this to happen. Cerny preferred to let developers patch in on performance improvements or for the system to run in a PS4 "base" mode to keep performance parallel.

Post-release Of The Update

Post-release, it was confirmed by sources that the PlayStation 4 Pro base mode would not improve games that did not receive patches. PlayStation 4 Pro players have been requesting for a feature like this to help some titles not receiving a Pro patch such as Bloodborne, The Witcher 3, Just Cause 3, and Batman: Arkham Knight.

Now, they no longer need to wait.

The New Update Hype

According to TheTechPortal, the initial rumor of Boost mode caused a sudden rush on Reddit and NeoGaf as PS4 Pro players flocked to get any available codes to try out the new mode for the previously-mentioned games. This has enabled many players to get into the beta and try out the mode for themselves.

With this update, Sony has finally allowed players to let the beast out of the up-clocked Jaguar CPU in the Pro, and there seems to be a little downside towards doing so thus far.
