This post on the Khronos developer blog seeks to clarify the misunderstanding (stemming from statements made during Khronos GDC presentations) that Vulkan Multi-GPU support was a Windows 10 only feature.
One key question that we have been asked since GDC is whether the Vulkan multi-GPU functionality is specifically tied to ship only on Windows 10. The good news is that the Vulkan multi-GPU specification is very definitely NOT tied to Windows 10. It is possible to implement the Vulkan multi-GPU extension on any desktop OS including Windows 7, 8.X and 10 and Linux.
