We already wrote about the PlayStation 4's upcoming Patch 4.50, which went into beta this weekend. One surprising note is on PlayStation 4 Pro there's an all-new Boost Mode, which improves the performance of game with Pro Mode patches. This wasn't in the release notes, but mention of the mode appeared on NeoGAF via a user with a Japanese PS4 Pro.
Eurogamer later obtained access to the beta and confirmed that Boost Mode was real.
Sony told The Verge that Boost Mode lets the PlayStation 4 Pro improve non-Pro games. If a game has a variable framerate, this can mean higher framerates. Games that aim for 30 FPS, but have drops will have fewer missed frames. There are also reports of shorter loading times and other benefits. The closer a game is to its peak or intended performance, the less likely you'll see a benefit from Boost Mode.
"Boost Mode lets PS4 Pro run at a higher GPU and CPU clock speed in order to improve gameplay on some PS4 games that were released before the launch of PS4 Pro," a Sony spokesperson told The Verge. "Games that have a variable frame rate may benefit from a higher frame rate, and load times may be shorter in some games too."
Videos have already released of The Evil Within on PlayStation 4 Pro without the framerate stuttering that affects the normal version. There have also been similar videos released for Just Cause 3, The Witcher 3: Wild Hunt, and Bloodborne (Video #2).
Depending on how well it works, Sony may be ready to sell a bunch more PlayStation 4 Pro systems.
