D3D11_QUERY_DATA_TIMESTAMP_DISJOINT Structure

Query information about the reliability of a timestamp query.

Syntax

typedef struct D3D11_QUERY_DATA_TIMESTAMP_DISJOINT {
    UINT64 Frequency;
    BOOL Disjoint;
} D3D11_QUERY_DATA_TIMESTAMP_DISJOINT;  

Members

Frequency
How frequently the GPU counter increments in Hz.

Disjoint
If this is TRUE, something occurred in between the query’s ID3D11DeviceContext::Begin and ID3D11DeviceContext::End calls that caused the timestamp counter to become discontinuous or disjoint, such as unplugging the AC chord on a laptop, overheating, or throttling up/down due to laptop savings events. The timestamp returned by ID3D11DeviceContext::GetData for a timestamp query is only reliable if Disjoint is FALSE.

Remarks

For a list of query types see D3D11_QUERY.
