Valve have updated the Beta of Steam Play which fixes VR games, fullscreen improvements and more

Another Beta version of Proton is available for Valve's Steam Play for those who wish to give it a go with the latest fixes.

To avoid some confusion: The Steam Play system as a whole is still in Beta, Proton (Valve's Wine fork) which Steam Play uses has a "3.7-3" version which is the default, but you can also switch to the Beta version of Proton itself in Steam's settings (compatibility tool dropdown box) to get Proton "3.7-6" which was just released today.

Proton 3.7-6 highlights:

• Fix failure to start VR games.
• Improvements to fullscreen games running at non-native resolutions.
• Compatibility fix for games that use Steam integration.
• Return to previous D3D10 behavior in DXVK to allow games to fallback to D3D9.

Getting it to actually show up in Steam is a bit odd still. Even on a fresh boot today, I had to quit and reload Steam to get the new Beta of Proton to actually show up. Hopefully Valve will improve the user experience there when the Steam Play system is a bit further along.

Also, Valve has now upped the NVIDIA driver requirement to 396.54.
