First, let me elaborate on my understanding of Vulkan and SPIR-V themselves: if I understand correctly, Vulkan API are implemented as drivers and consume SPIR-V used by applications to communicate with drivers. Please do correct me if I'm wrong.
With that understanding aside, does either the API implementation or IR language have anything that represent hardware features that's missing from OpenGL 2.1/3.3, DirectX 9 era GPUs? Other than raw computing ability of old hardware, is there any limitations on getting those hardware to effectively run Vulkan?
