Constants
-
D3DQUERYTYPE_VCACHE
-
Query for driver hints about data layout for vertex caching.
-
D3DQUERYTYPE_ResourceManager
-
Query the resource manager. For this query, the device behavior flags must include D3DCREATE_DISABLE_DRIVER_MANAGEMENT.
-
D3DQUERYTYPE_VERTEXSTATS
-
Query vertex statistics.
-
D3DQUERYTYPE_EVENT
-
Query for any and all asynchronous events that have been issued from API calls.
-
D3DQUERYTYPE_OCCLUSION
-
An occlusion query returns the number of pixels (or samples when multisampling is enabled) that pass z-testing. These pixels/samples are for primitives drawn between the issue of D3DISSUE_BEGIN and D3DISSUE_END. This enables an application to check the occlusion result against 0. Zero is fully occluded, which means the pixels/samples are not visible from the current camera position. To get the number of pixels when a multisampled render target is used, the result should be divided by the sample count of the target.
-
D3DQUERYTYPE_TIMESTAMP
-
Returns a 64-bit timestamp.
-
D3DQUERYTYPE_TIMESTAMPDISJOINT
-
Use this query to notify an application if the counter frequency has changed from the D3DQUERYTYPE_TIMESTAMP.
-
D3DQUERYTYPE_TIMESTAMPFREQ
-
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.
-
D3DQUERYTYPE_PIPELINETIMINGS
-
Percent of time processing pipeline data.
-
D3DQUERYTYPE_INTERFACETIMINGS
-
Percent of time processing data in the driver.
-
D3DQUERYTYPE_VERTEXTIMINGS
-
Percent of time processing vertex shader data.
-
D3DQUERYTYPE_PIXELTIMINGS
-
Percent of time processing pixel shader data.
-
D3DQUERYTYPE_BANDWIDTHTIMINGS
-
Throughput measurement comparisons for help in understanding the performance of an application.
-
D3DQUERYTYPE_CACHEUTILIZATION
-
Measure the cache hit-rate performance for textures and indexed vertices.
-
D3DQUERYTYPE_MEMORYPRESSURE
-
Efficiency of memory allocation contained in a D3DMEMORYPRESSURE structure.
Differences between Direct3D 9 and Direct3D 9Ex:
- D3DQUERYTYPE_MEMORYPRESSURE is only available in Direct3D9Ex running on Windows 7 (or more current operating system).
