VKD3D-Proton 3.0 brings FSR4 support, shader backend rewrite, lots of bug fixes and performance upgrades

VKD3D-Proton is one of the secret ingredients for Proton to make so many Windows games work well on Linux / SteamOS with a new 3.0 release out now.

You don't need to actually do anything to upgrade, as Valve pull in VKD3D-Proton changes for Proton versions themselves that you'll see in future Proton release updates. However, if you wish to try it out in the current version of Proton we have a GamingOnLinux guide to tell you what to do.
