Valve Continued Doing A Lot For Linux Gaming & Open-Source Radeon Drivers In 2020

VALVE --
Valve this year continued contributing significantly to not only improving the Linux gaming experience but also the Linux desktop at large with their continued open-source graphics driver enhancements and other infrastructure work.

Open-source driver developers working under contract for Valve continued pushing along the open-source Radeon Vulkan "RADV" driver, pushed the "ACO" compiler back-end for RADV into excellent shape that it's now enabled by default and delivers excellent performance, continued work on the Linux VR support as well as their engagements with Collabora and the like, and other infrastructure work such as backing the SUD functionality and other ongoing kernel work.


Steam Play's Proton downstream of Wine also continued evolving nicely this year and saw many new games running on Linux -- including new titles like Cyberpunk 2077. Thanks to Valve's backing, DXVK and VKD3D-Proton also continued maturing excellently for Direct3D atop Vulkan.

So while Steam on Linux still struggles for a 1% marketshare, Valve continues investing a lot into the Linux scene and with areas like the Vulkan driver work benefit the Linux desktop at large. It will be interesting to see in 2021 what more Valve will do and whether we will see the reintroduction yet of SteamOS or Steam Machines.

Here's a look back at the most popular Valve/Steam-related articles on Phoronix for 2020:
