Proton 11 Beta arrives to bring enhanced gaming compatibility to Linux / SteamOS

Valve just put up a Beta for Proton 11, the next major release of their compatibility layer to run Windows games on Linux / SteamOS. This brings with it quite a lot of enhancements, with it being based on Wine 11 it also brings with it support for the new NTSync which in some cases can improve game performance (but don't expect huge gains here).

They also appear to have released the ARM64 build of Proton too with FEX, which is now available to install in your Steam Library which is no doubt work towards the Steam Frame. But, it should work on any ARM64 machine.

Some really incredible work has gone into this release. Gaming on Linux continues to get steady improvements!
