    Vulkan support on prime systems right now sucks, not only on amd, also on nvidia, since bumblebee doesn't support it

      It's actually a feature of Vulkan. It enumerates all devices that support the API and exposes them to the application.

        But there would still need to be something to copy the frames to the main GPU. Unless the game handles that.

          Vulkan doesn't yet properly support multi GPU setup as far as I know. It's only WIP.

            The application would handle combining the results from various devices as necessary.
