I'd like to be able to detect what GPU is selected as default on Windows for Vulkan, so if anyone has a modern laptop with a dual GPU, please enable the Vulkan backend -> check the order of the GPUs listed in settings -> graphics -> graphics cards (in the client).
Then change the default GPU to the one that is not the first entry and redo it.
If the order changes its clear, that the default GPU always comes first.
If not I've no idea if we can detect it.
It would be nice to know this ...
