More information
Command syntax
| Parameter | Description |
|---|---|
-saveBMP |
By using this parameter, the test saves presented images in BMP format to the test directory in case of conformance failure. This is useful for diagnosing conformance failures. |
-whql | -featurelevel:<fl> |
-whql results in device creation with highest support on a given adapter. –featurelevel:<fl> creates a device of requested feature level Default value: -wqhl for DX10+ drivers; -featurelevel:9.1 for DX9 drivers |
-hybrid |
This value forces application execution on dGPU as if it was on the DList. |
