Translating DirectX 9/10/11 or OpenGL to Vulkan commands is unlikely to bring any performance improvements over existing solutions. OpenGL and DirectX 9/10/11 drivers are already employing highly tuned heuristics and tricks to bring out the best possible performance given the limitations of these APIs.
I'm a complete ignorant. But given that Gallium Nine improves DX9 performance, can we possibly expect the same for Vulkan? G9 only works with open source AMD driver, but Vulkan will be supported by both nvidia and amd proprietary drivers. That's what made me think performance could be better.
