Constants

 
D3DDDIQUERYTYPE_VCACHE
Query at issue end for driver hints about data layout for vertex caching. This query is processed through a call to the driver's IssueQuery function in which the End bit-field flag is set in the Flags member of the D3DDDIARG_ISSUEQUERY structure.
D3DDDIQUERYTYPE_RESOURCEMANAGER
Query the driver's resource manager.
D3DDDIQUERYTYPE_VERTEXSTATS
Query for the vertex stats.
D3DDDIQUERYTYPE_DDISTATS
Query for the DDI stats.
D3DDDIQUERYTYPE_EVENT
Query at issue end for asynchronous events that have occurred.
D3DDDIQUERYTYPE_OCCLUSION
Query for the number of pixels that pass z-testing. These pixels are for primitives that are drawn between an issue begin and an issue end.

This query is processed between calls to the driver's IssueQuery function in which first the Begin bit-field flag is set in the Flags member of the D3DDDIARG_ISSUEQUERY structure and next the End bit-field flag is set.

This query enables an application to check the occlusion result against 0. A value of 0 is "fully occluded," which means the pixels are not visible from the current camera position.
D3DDDIQUERYTYPE_TIMESTAMP
Query at issue end for the 64-bit timestamp.
D3DDDIQUERYTYPE_TIMESTAMPDISJOINT
This query is used to notify an application whether the counter frequency has changed from the value that is returned from the D3DQUERYTYPE_TIMESTAMP query.
D3DDDIQUERYTYPE_TIMESTAMPFREQ
The GPU timestamp frequency for resolving query timestamps.

This query result is TRUE if the values from D3DQUERYTYPE_TIMESTAMP queries cannot be guaranteed to be continuous throughout the duration of the D3DQUERYTYPE_TIMESTAMPDISJOINT query. Otherwise, the query result is FALSE.
D3DDDIQUERYTYPE_PIPELINETIMINGS
Query for the percent of processing time spent on pipeline data.
D3DDDIQUERYTYPE_INTERFACETIMINGS
Query for the percent of processing time spent on data in the driver.
D3DDDIQUERYTYPE_VERTEXTIMINGS
Query for the percent of processing time spent on vertex shader data.
D3DDDIQUERYTYPE_PIXELTIMINGS
Query for the percent of processing time spent on pixel shader data.
D3DDDIQUERYTYPE_BANDWIDTHTIMINGS
Query for throughput measurements for help in understanding the performance of an application.
D3DDDIQUERYTYPE_CACHEUTILIZATION
Query for the cache hit-rate performance for textures and indexed vertices.
D3DDDIQUERYTYPE_COUNTER_DEVICE_DEPENDENT
Query for device-dependent counters.
