Sony is taking the wraps off of its latest firmware with the release of version 4.50 “Sasuke” beta firmware for the PS4. With the new firmware, Sony is rolling out a number of UI/UX improvement and users will finally be able to use external storage with the game console. On the PS4 Pro front, Sony will be adding a “boost mode” in a future update (it may not be ready in time for a production 4.50 release) that lets legacy games access the additional GPU horsepower of the Pro version of the console to smooth out frame rates without needing any special patches from the game developers.
The new firmware adds support for USB 3.0 hard drives (or SSDs) up to 8TB. Users will be able to use the external storage to store games, downloaded applications, screenshots, and videos and have it all show up on the main system menu along with the local storage. Users will not need to shuffle game data back and forth in order to play their games either. Note that currently, the actual save game data is still stored locally even if the game itself is stored on the external hard drive. Fans of the PlayStation VR (PS VR) also get an update with firmware 4.50 in the form of support for watching 3D Blu Rays. Beyond those big feature updates, Sony is also changing up the interface slightly. The Quick Menu now takes up less screen space and will allow gamers to create and join parties right from there rather than going to a separate app. In the notification area, Sony has condensed all the various notification types into a single unified list. Further, users will be able to set in game screenshots as the home screen wallpaper.
Perhaps most interesting is the planned “boost mode” for the PS4 Pro which is currently in beta. Gamers are reporting that titles such as The Evil Within and Just Cause 3 are significantly smoother frame rates with noticeably reduced stuttering. Reportedly, the boost mode will work with most PS4 games that were programmed with unlocked frame rates though the exact benefits will vary. Games that have a hard cap on the frame rate will still need specific patches from the game developers to get any improvements. Ars Technica speculates that the “boost mode” is simply Sony removing its own blocks it put in place to force compatibility with older games that were developed with the base PS4 in mind. When the boost mode is off, the PS4 Pro GPU has part of itself turned off such that it functions exactly as the PS4’s GPU and activating boost mode takes away the blocks and allows the full GPU (with it's 36 CUs) to process the game data as best it can. Getting things like native higher resolutions or more detailed textures will still require patches, of course.
If you have a PS4 or PS4 Pro, keep an eye on the beta Sasuke 4.50 firmware.
