D3DKMT_ADAPTER_PERFDATACAPS structure (d3dkmthk.h)

The D3DKMT_ADAPTER_PERFDATACAPS structure represents data capabilities that are static and queried once per GPU during initialization.

Syntax

typedef struct _D3DKMT_ADAPTER_PERFDATACAPS {
  UINT32                   PhysicalAdapterIndex;
  D3DKMT_ALIGN64 ULONGLONG MaxMemoryBandwidth;
