Without the loader, you can still load the driver DLL directly. You just have to use vkGetInstance/DeviceProcAddr for everything because drivers don't expose the Vulkan 1.0 API symbols (the loader does). We'd also have to come up with a story for window-system integration, as Jesse alluded. I'd love to see Mesa used to bring Vulkan to consoles! Unfortunately, no one's working on that currently or has any plans, as far as I know. --Jason > > 1. > 2.
