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. More concrete patch notes can be found below:
