Developer Mike Blumenkrantz has announced that they're now being funded by Valve, so Blumenkrantz's work on the OpenGL implementation on top of Vulkan with 'Zink' will continue.

Hold on, what actually is Zink? As described by Collabora dev Erik Faye-Lund it's an "OpenGL implementation on top of Vulkan. Or to be a bit more specific, Zink is a Mesa Gallium driver that leverages the existing OpenGL implementation in Mesa to provide hardware accelerated OpenGL when only a Vulkan driver is available".

After working on Zink for a while, Mike Blumenkrantz posted a blog entry back on November 6 saying it was the "last day" due to the end of it being hobby work while being between jobs. In a new blog post titled "Don't Call It A Comeback", Blumenkrantz mentions that "Valve has generously agreed to sponsor my work on graphics-related projects" and that the focus will be on Zink.

The plan for Zink is a big one and things are moving quickly. Working together with Collabora developer Erik Faye-Lund, together they're doing "Operation Oxidize" to get the majority of their work in progress code for Zink into mainline Mesa by the end of the year. This will give Zink basic OpenGL 4.6 and OpenGL ES 3.2 support along with "vastly" improved performance.

Nice to see Valve continuing to get involved with open source and Linux to improve all sorts of areas.

For those curious on the question of why — well, Vulkan is the future. This video can explain it in more details:

There are some Mali APU's (GPU) that do quite well at 3D graphics now. But typically that is done on Vulkan API. Snapdragon is the APU that has the most GPU performance currently but I don't think that is part of ARM?

The GPU in the M1 performs at roughly the level of the 1050 Ti. Later models, or models in machines with a higher power budget, are likely to get more performance.

Apple aren't going to move away from Metal unless they come up with something else that they completely control. They control the full hardware stack, the OS, the APIs, and the tools that devs are able to use. They can change any of them at will to benefit what they want to do with the Apple ecosystem.

yeah its a imprisoned ecosystem/market.. Just like how some of their manufacturing process employ forced labourers. Model is through and through.... lmao
