Subnautica now takes up a lot less hard drive space on PS5 compared to PS4 thanks to the new-gen console's lightning-quick SSD.

As Twisted Voxel reports (via Push Square), a new update reduces Subnautica's file size on PS5 from 14GB all the way down to just 3.5GB, a 70% reduction from the PS4 version. This is possible due to the compression tech afforded by the PS5 SSD's advanced data-streaming efficiency, which developer Unknown Worlds has utilized to make Subnautica a far less cumbersome game to have stored in your PS5's library.

After first launching out of Early Access in 2018, Subnautica made its new-gen debut on PS5 and Xbox Series X this month alongside the release of its sequel, Subnautica: Below Zero. The PS5/Xbox Series X version of Subnautica includes a 60FPS performance mode as an alternative to the 4K fidelity mode, though Unknown Worlds told GamesRadar+ that the updated version doesn't support DualSense features like haptic feedback and adaptive triggers "just yet."

After earning an English degree from ASU, I worked as a corporate copy editor while freelancing for places like SFX Magazine, Screen Rant, Game Revolution, and MMORPG on the side. I got my big break here in 2019 with a freelance news gig, and I was hired on as GamesRadar's west coast Staff Writer in 2021. That means I'm responsible for managing the site's western regional executive branch, AKA my home office, and writing about whatever horror game I'm too afraid to finish.
