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 that pass z-testing. These pixels 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 are not visible from the current camera position.

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.
