Valve’s Pierre-Loup A. Griffais shared, “This update upgrades the Catalyst driver in our repositories with a preview release. This build should fix the poor in-game performance and malfunctioning return to desktop functionality. Known problems include tearing and poor overlay performance in-game; please install them and post your feedback!”
SteamOS installs should update themselves by themselves, but the refreshed installation images will also be made available to download. Do bear in mind that SteamOS does have minimum requirements, where among them include a 64-bit processor, 4GB RAM, at least 500GB of hard drive space, and support for UEFI booting. One thing is for sure though, there is an onslaught of Steam machines coming our way.
