Hybrid - Independent Driver Update (Discrete GPU)
The test uses the Microsoft Basic Render device as dGPU paired with IHV iGPU. A basic Hybrid Present test is run on this configuration to validate that it is still a valid Hybrid configuration and that Hybrid functionality is preserved.

| Error | Description |
|---|---|
Conformance issues |
When the test detects a conformance issue, it saves an image in the test directory if the -saveBMP parameter is specified. You can view this image to help diagnose the issue. |
Cross Adapter Present validation failures |
To get more information about the failure, run the test under User Mode Debugger. The test will output the information that it gets from ETW events, to help diagnose the failure. |

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. |
