This is fantastic. I'm not some Linux fanboy, but I am increasingly disillusioned that Microsoft cares to make Windows good in any meaningful way. Vulkan seems to be a far more efficient low-level graphics API compared to DirectX these days, and what's been coming out of Valve seems to support that idea: a lot of performance issues on Linux are solvable problems.

I'm writing this from my Steam Deck which has become a more than capable general use PC even on its limited hardware. I was planning on getting a Steam Machine, and this ongoing work Valve is doing only makes me more confident in using that cute little box as a full jump away from the Microsoft stack. I recognize that's not a viable option for everyone out there, but I'm excited to try.
