The D3DKMT_ENUMADAPTERS3 structure supplies information about adapters on the system.
Filter [in]A D3DKMT_ENUMADAPTERS_FILTER union containing filter flags for the enumeration. The struct in Filter can be a bitwise OR of the following values. See Remarks for more information.
| Value | Meaning |
|---|---|
| IncludeComputeOnly | When set, enumerate ComputeOnly adapters. |
| IncludeDisplayOnly | When set, enumerate DisplayOnly adapters. |
| IncludeVirtualGpuOnly | When set, enumerate GPU-P adapters. These adapters are meant to be used only inside virtual machines. A driver sets the DXGK_DRIVERCAPS::MiscCaps.VirtualGpuOnly cap for such adapters to avoid their enumeration in the host OS. Available starting in Windows 11, version 24H2 (WDDM 3.2). |
| Reserved | Reserved; do not use. |
NumAdapters [in/out]The number of adapters.
On input, NumAdapters specifies how many adapters can be returned in the empty pAdapters array. Possible return values for NumAdapters are:
pAdapters [out]An optional array of D3DKMT_ADAPTERINFO structures in which to receive information for each adapter.
Adapters will still be enumerated if no flags are set in Filter, but D3DKMTEnumAdapters3 will enumerate fewer adapters than D3DKMTEnumAdapters2. Specifically, D3DKMTEnumAdapters3 will:
