Constants

Constant	Description
D3D12_QUERY_TYPE_OCCLUSION	Indicates the query is for depth/stencil occlusion counts.
D3D12_QUERY_TYPE_BINARY_OCCLUSION	Indicates the query is for a binary depth/stencil occlusion statistics. This query type acts like D3D12_QUERY_TYPE_OCCLUSION except that it returns simply a binary 0/1 result: 0 indicates that no samples passed depth and stencil testing, 1 indicates that at least one sample passed depth and stencil testing. This enables occlusion queries to not interfere with any GPU performance optimization associated with depth/stencil testing.
D3D12_QUERY_TYPE_TIMESTAMP	Indicates the query is for high definition GPU and CPU timestamps.
D3D12_QUERY_TYPE_PIPELINE_STATISTICS	Indicates the query type is for graphics pipeline statistics, refer to D3D12_QUERY_DATA_PIPELINE_STATISTICS.
D3D12_QUERY_TYPE_SO_STATISTICS_STREAM0	Stream 0 output statistics. In Direct3D 12 there is no single stream output (SO) overflow query for all the output streams. Apps need to issue multiple single-stream queries, and then correlate the results. Stream output is the ability of the GPU to write vertices to a buffer. The stream output counters monitor progress.
D3D12_QUERY_TYPE_SO_STATISTICS_STREAM1	Stream 1 output statistics.
D3D12_QUERY_TYPE_SO_STATISTICS_STREAM2	Stream 2 output statistics.
D3D12_QUERY_TYPE_SO_STATISTICS_STREAM3	Stream 3 output statistics.
D3D12XBOX_QUERY_TYPE_PREDICATION_STATUS	Predication performance statistics.
