ID3D11Counter interface (d3d11.h)
This interface encapsulates methods for measuring GPU performance.
Inheritance
The ID3D11Counter interface inherits from ID3D11Asynchronous. ID3D11Counter also has these types of members:
Methods
The ID3D11Counter interface has these methods.
| ID3D11Counter::GetDesc Get a counter description. (ID3D11Counter.GetDesc) |
Remarks
A counter can be created with ID3D11Device::CreateCounter.
This is a derived class of ID3D11Asynchronous.
Counter data is gathered by issuing an ID3D11DeviceContext::Begin command, issuing some graphics commands, issuing an ID3D11DeviceContext::End command, and then calling ID3D11DeviceContext::GetData to get data about what happened in between the Begin and End calls. The data returned by GetData will be different depending on the type of counter. The call to End causes the data returned by GetData to be accurate up until the last call to End.
Counters are best suited for profiling.
For a list of the types of performance counters, see D3D11_COUNTER.
