Khronos Delays Vulkan Graphics API To 2016 Release (phoronix.com)

An anonymous reader writes: The Khronos Group has announced that the Vulkan specification is complete and undergoing legal review and final polishing, but it means that Vulkan will not be published this year. Khronos reports that the Vulkan 1.0 specification will be published when the first conformant implementations are confirmed. Phoronix received some more details about the state of Vulkan in that there were a lot of changes since GDC and " the gating factor for release will be availability of product-quality implementations."

Re:What the fuck is "Vulkan"?

GPU drivers. Like OpenGL, but.....modern. An open-source alternative to AMD/NVIDIA/Intel's closed-source proprietary drivers, but should work better than existing open-source solutions. At least, that's my basic understanding of it. I could be wrong.

Vulkan is not a driver, it's the next generation OpenGL API for writing accelerated 3D graphics and compute code. AMD, nVidia, Intel etc. will have drivers implementing this interface. Like DirectX 12 and the defunct AMD Mantle, it provides a much more low level interface than traditional DirectX/OpenGL which means drivers should be simpler. Intel has an open source driver, AMD starts closed source but has promised to open it up while nVidia will probably remain closed source. The offset is of course that when the driver does less, your code must do more. Typically that would be the job of a game engine or something similar.

This is the culmination of a process that has been going on for a very long time from fixed function hardware to programmable shaders to generic computing capability and what we call "drivers" today really being giant libraries running on top. The Vulkan API exposes that generic low-level capability directly. I don't think the high-level interface is going away though, but it's been unclear to me if that's going to stay in the 4.x series or not. At least Microsoft called it all DirectX 12, but then they control the whole platform. On open source it's likely you'll have full Vulkan support, but still OpenGL 4.x functions missing.
