Phoronix: Zink Is Now OpenGL 3.0 Complete For Generic GL Over Vulkan

A few days ago I wrote about Zink now exposing GLSL 1.30 shader support as one of the few remaining hurdles for exposing OpenGL 3.0 support for this Gallium3D OpenGL-on-Vulkan implementation. It turns out this same week, Zink would already cross the significant OpenGL 3.0 milestone...

Now I'm starting to wonder if one day we will have OGVK (like DXVK, but for OpenGL) to play Linux native OpenGL games faster.
I'm not sure if there are games that are OpenGL for both platforms.

Phoronix: Zink Is Now OpenGL 3.0 Complete For Generic GL Over Vulkan
For reaching OpenGL 3.1, Zink still has to support NV_primitive_restart and ARB_uniform_buffer_object. For OpenGL 3.1, Zink has several more extensions to go and likewise for OpenGL 3.3 but some

Should that be OpenGL 3.2?

Zink is already this OGVK you talk about. That is its job, to provide an OpenGL implementation running on Vulkan drivers. When it becomes optimized enough, it could be used exactly like DXVK, even on Windows (for example for AMD gpus which have poor OpenGL support on the official driver).

At least Alien Isolation OpenGL in Linux Native. Playing it with Wine DXVK is faster. It would be really intressting how fast it is with Native + Zink

This would only be useful assuming one day drivers will do away with OpenGL support. Which I don't see happening.
What about performance, is it comparable with just going OpenGL?

Problem is, Alien Isolation uses an OpenGL wrapper i think. That is, it already uses a custom-made DXVK-like layer in order to run on OpenGL. So running the Linux version of Alien Isolation on Zink, it would essentially be running under 2 layers, one on top of the other. D3D->OpenGL->Vulkan. Why not cut the middleman and go D3D->Vulkan in that case, using DXVK?

That's great but hopefully it could be merged into DXVK one day so we can install only one thing and play both DirectX + OpenGL games.
If we could use it on Windows too, then that would be really awesome too!

Yes you are right. I forgot that step.

But you never know...good example https://flightlessmango.com/benchmarks/6RfJoH1N6IQ

I'm happy to see it progressing, OpenGL 3.0 seems like an important step forward Will try Mesa-git again, hope it can run now some more applications. Hope Zink gets enabled with Mesa 20.2 in Arch Linux for early testers.
