The frontend picks the adapter and hands over its device, so the core no longer loads dxgi.dll, creates DXGI factories, enumerates adapters or creates throwaway D3D11/D3D12 devices to query AA modes and logic op support at load. Until the device arrives the AA modes are the counts every device has; the context reset fills them in from the real device (D3D12 now too) and re-validates the MSAA setting against them.
