--- Comment #1 from Józef Kucia joseph.kucia@gmail.com --- It's a known problem. Wine DXGI doesn't have a proper support for multiple adapters yet. I plan to revisit multiple adapters support when we have stable adapter LUIDs.
Other than that, vkd3d itself could also use a heuristic to select a physical device, when the library user doesn't select the physical device explicitly.
