A fresh update to Proton Experimental has gone live, the special version of the Proton compatibility layer where all the latest features appear first. Seems like quite a big one, especially if you have a VR kit.
Need more info on what Steam Play and Proton are? It's a compatibility layer that allows you to run Windows games on Linux. See our dedicated page for more.
In the update released January 7, Proton Experimental gained support for the new OpenXR virtual reality API which now means that Microsoft Flight Simulator can work in VR mode with compatible headsets and they specifically mention "AMD hardware.
Gamepad support has been improved too with hotplugging working nicer with Subnautica, many other Unity titles and DOOM (2016). Yakuza: Like a Dragon should also see improved Xbox controller support. Additionally they now support setting thread priorities via RTKit, or Unix priorities if your user has permissions.
