WGF11 Precision
This automated test ensures that when shaders specify the minimum partial precision flag (8, 10, or 16-bit) that IHVs do not use a lower precision for calculations. For example, the shader specifies 16-bit but the IHV uses 10-bit.
This topic is applicable to the following test cases:
WGF11 Precision
WGF11 Precision (WoW64)
WGF11 Precision FL9.3
WGF11 Precision FL9.3 (WoW64)
Note
Using higher precision than the minimum specified value is valid.

Running the test
Before you run the test, complete the test setup as described in the test requirements: Graphic Adapter or Chipset Testing Prerequisites.
Troubleshooting
For troubleshooting information, see Troubleshooting Device.Graphics Testing.
This test will always return Pass if precision is handled correctly, or return Fail if not. To review test details, review the test log from the Windows HCK Manager.
If the partial precision test fails, try setting your driver to ignore the partial precision flags. If that passes, then it means that when you are attempting to follow the partial precision flags, you are using a lower precision than what the shader specified. E.g. The shader asked for 16-bit minimum, but you are using 8-bit or 10-bit. If you ignore the partial precision flags, and it still fails, ensure other conformance tests pass because the test relies on things like “sample” working correctly.

The partial precision group in WGF11Precision.exe ensures that when shaders specify the minimum partial precision flag (8, 10, or 16-bit) that IHVs do not use a lower precision for calculations. For example, the shader specifies 16-bit but the IHV uses 10-bit. Using higher precision than the minimum specified value is valid.
