IDARG_IN_ADAPTERSETRENDERADAPTER structure

Description

The IDARG_IN_ADAPTERSETRENDERADAPTER structure identifies the render adapter that the driver wants to be used to render the desktop image for the swapchains on this adapter.

Members

`PreferredRenderAdapter`

Locally unique identifier (LUID) that identifies the driver's preferred adapter. Setting a value of {0, 0} indicates that the driver has no preference for the render adapter used.

The driver's specified adapter is a preference and the OS might decide to use a different render adapter. For example, if the specified adapter has been PnpStopped then the OS will pick an alternative.
