Bug ID: 46510
           Summary: Vkd3d is confused on optimus systems.
           Product: vkd3d
           Version: 1.1
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: vkd3d
          Assignee: [e-mail]

When on integrated card, wine crashes. When discrete card is enabled following
error message is reported: 
fixme:vkd3d_select_physical_device: Multiple physical devices available,
selecting the first one.

DXVK works around this problem by selecting discrete card over integrated one.
If dicrete isn't shown, integrated will be used instead.

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.

The default physical device selection heuristic is improved by

A separate bug could be opened for better multiple adapters support in DXGI.
