It does, however, still work quite well with the Windows version via Steam Play Proton on desktop Linux and is Steam Deck Verified against the Windows version in Proton. So while it’s a loss of support for their Native build, it’s still fully playable on Linux.
Hopefully they will focus on shared improvements and not just have wine and dxvk do all of the heavy lifting.
I would be ok with less native titles if big lifts like vulkan support happened instead
