_D3DKMT_ADAPTER_PERFDATA structure

Description

Contains input arguments for the D3DKMTQueryAdapterInfo function. Represents performance data collected per adapter on an interval basis.

Members

`PhysicalAdapterIndex`

The physical adapter index in the LDA (linked display adapter) chain.

`MemoryFrequency`

Clock frequency of the memory, represented in hertz.

`MaxMemoryFrequency`

Max clock frequency of the memory while not overclocked, represented in hertz.

`MaxMemoryFrequencyOC`

Max clock frequency of the memory while overclocked, represented in hertz.

`MemoryBandwidth`

– Amount of total memory transferred in bytes.

`PCIEBandwidth`

Amount of total memory transferred over the PCIE in bytes.

`FanRPM`

The current rpm of the main fan.

`Power`

The current power draw of the adapter in tenths of percentage, 1 = 0.1%.

`Temperature`

The main temperature sensors reading in decimal Celsius. 1 = 0.1C.

`PowerStateOverride`

Reports if the GPU is powered on with 1 otherwise it is 0.
