# D3D10_COUNTER_INFO structure


## -description


Information about the video card's performance counter capabilities.


## -struct-fields




### -field LastDeviceDependentCounter

Type: <b><a href="https://docs.microsoft.com/windows/desktop/api/d3d10/ne-d3d10-d3d10_counter">D3D10_COUNTER</a></b>

Largest device-dependent counter ID that the device supports. If none are supported, this value will be 0. Otherwise it will be greater than or equal to D3D10_COUNTER_DEVICE_DEPENDENT_0. See <a href="https://docs.microsoft.com/windows/desktop/api/d3d10/ne-d3d10-d3d10_counter">D3D10_COUNTER</a>.


### -field NumSimultaneousCounters

Type: <b><a href="https://docs.microsoft.com/windows/desktop/WinProg/windows-data-types">UINT</a></b>

Number of counters that can be simultaneously supported.


### -field NumDetectableParallelUnits

Type: <b>UINT8</b>

Number of detectable parallel units that the counter is able to discern. Values are 1 ~ 4. Use NumDetectableParallelUnits to interpret the values of the VERTEX_PROCESSING, GEOMETRY_PROCESSING, PIXEL_PROCESSING, and OTHER_GPU_PROCESSING counters. See <a href="https://docs.microsoft.com/windows/desktop/api/d3d10/nf-d3d10-id3d10asynchronous-getdata">ID3D10Asynchronous::GetData</a> for an equation.
