The Steam Deck’s been in the hands of the public for some time now and is essentially a super portable version of Valve’s online gaming service. Running off of its own operating system known as SteamOS, it’s received a new update for both Steam Deck users and those loading the Arch Linux-based OS image onto their own devices.

Titled the SteamOS Beta 3.3, the update’s already off to a good start offering increased graphics driver support, meant to enhance game compatibility, and performance enhancements to the AMD Radeon open-source driver stack. Previously, users could disconnect when connected to WiFi on a 5GHz network, and that was fixed in this update as well.
