vulkan_device

std::optional<GHOST_DeviceVK> vulkan_device

static

A shared device between multiple contexts.

The logical device needs to be shared as multiple contexts can be created and the logical vulkan device they share should be the same otherwise memory operations might be done on the incorrect device.
