I think Metal 2 will be activated this spring with external GPU support, because that's one of the features of Metal 2. Maybe that will also enable HEVC H.265 support for the GPU because Apple says, "Metal 2 includes features that empower the GPU to take control over key aspects of the graphics and compute pipelines. Essential tasks, such as the assigning of resources to shaders, can now be efficiently driven by the GPU instead of waiting on the CPU."
