The next big PlayStation 4 firmware update, update 4.50, is now in the hands of beta testers, who are able to enjoy the new features before everybody else. Among these new features is Boost Mode, which allows unpatched games to enjoy better performance on PlayStation 4 Pro, and it seems like improvements will be quite noticeable, judging from several videos that have surfaced online recently.

　　The new PlayStation 4 Pro Boost Mode videos, which can be watched right below, show how Just Cause 3 and Rainbow Six Siege run on the new Sony console with Boost Mode active. Just Cause 3 definitely feels much better, as the game suffers from several issues while running on the original PlayStation 4 console.

　　Interestingly enough, the PlayStation 4 Pro Boost Mode also manages to improve the performance of a rather popular demo, Final Fantasy XV: Episode Duscae. On PS4 Pro with Boost Mode, the frame rate is much more solid than on the regular console.

　　The PlayStation 4 4.5 firmware update will also introduce external HDD support.

　　It’s easy to upgrade the HDD that came with your PS4, but if you’re still looking for more storage space on the console, we’ve got you covered. With this update, you have the option to store content to an external HDD. Just plug a USB 3.0 HDD into your PS4, and voilà, you now have more space on the console.

　　This is compatible with HDDs up to 8TB in size. You can download and install applications directly to your extra storage, and the saved contents are easily manageable through the settings menu. Also, all the applications saved in the external HDD will appear in the Content Launcher of the Home Screen so it’s easy to keep track of what apps you launched recently.

　　A release date for the PS4 4.50 update has yet to be confirmed. We will let you know more about the matter as soon as more comes in on it, so stay tuned for all the latest news.
