Description

The DXGK_ADAPTER_PERFDATACAPS structure describes the performance data capabilities of the adapter.

Members

`MaxMemoryBandwidth`

The maximum memory bandwidth in bytes for 1 second.

`MaxPCIEBandwidth`

The maximum PCIE bandwidth in bytes for 1 second.

`MaxFanRPM`

The maximum fan revolutions per minute of the main fan.

`TemperatureMax`

The maximum temperature before damage levels occur in deci-Celsius (a value of 1 = 0.1C).

`TemperatureWarning`

The temperature level where temperature based throttling begins in deci-Celsius (a value of 1 = 0.1C).

Remarks

KMD's DxgkDdiQueryAdapterInfo function should fill in the DXGK_ADAPTER_PERFDATACAPS structure in response to a DXGK_QUERYADAPTERINFOTYPE query of type DXGKQAITYPE_ADAPTERPERFDATA_CAPS.
