Sony has announced that the next major system software update for PS4, version 4.50, rolls out tomorrow. This update will bring lots of new features, such as allowing players to download and store PS4 games and apps to an external HDD, voice chat for remote play, custom wallpapers and profile colours, and more.
Starting with one of the most requested features, 4.50 allows you to download and store PS4 games and apps to an external HDD. All you have to do is insert your USB 3.0 HDD into your console, and select it from 'USB Storage Devices' from 'Devices' in Settings to format it so it's ready to use. Compatible HDDs need to be USB 3.0 or later, between 250GB (min) and 8TB (max).
4.50 brings several improvements to PS VR as well. If you're playing a game in PS VR, and you return to PS4's home screen, you may notice that the resolution looks lower than normal on the TV 'Social Screen'. Following this update, you'll find that the resolution of the system screen displayed on your TV is significantly better when you're out of VR mode.
Also, the resolution of Cinematic Mode on PS VR will improve "“ if your PS VR screen size is set to Small or Medium, the framerate of content viewed in Cinematic Mode goes up from 90Hz to 120Hz with this update. PS VR will now support Blu-ray 3D discs. You will have the ability to watch them in stereoscopic 3D via your headset.
This update will also add voice chat when using Remote Play on Windows PC, Mac or an Xperia device, off-console availability with a variety of off-console apps and features that make communication with other gamers easier, custom wallpapers by selecting any screenshot and set it as your new PS4 home screen wallpaper, and a new option to better personalise your profile page and its colour.
Your Activity Feed will also be a lot more "personal" after this update, as you will be able to create custom stories with text, screenshots, player and game tags. In addition, you can now change the privacy settings for individual posts. You can alter who sees your Activities via the same-named tab in the Sharing Your Experience section of Settings, while you can decide the level of privacy for videos, screenshots, broadcasts, PS Store and PS Music when you go to upload them.
Other small additions include a save data shortcut that allows you to more easily upload the saved data on your PS4 to PS Plus online storage and download the saved data from PS Plus online storage to your PS4 with ease, the option to chose a screenshot or video in Capture Gallery and go straight into SHAREfactory and start editing, and the ability to share GIFs from SHAREfactory to your Activity Feeds.
Finally, this update also brings the long awaited Boost Mode for PS4 Pro. This feature has been designed to provide better performance for legacy titles that have not been patched to take advantage of the PS4 Pro's faster CPU and its faster and double-sized GPU. This can provide a noticeable frame rate boost to some games with variable frame rates, and can provide frame rate stability for games that are programmed to run at 30 Hz or 60 Hz.
Depending on the game, the increased CPU speed may also result in shorter load times. Keep in mind that Boost Mode is not guaranteed to work with all titles. Turning the setting off will allow the game to be played in a mode that replicates the standard PS4.
You can turn on the Boost Mode from the PS4's Settings menu. Go to 'Settings', then 'System', then scroll down to 'Boost Mode' and tick the box to turn Boost Mode on.
