Running Shaders

To run shaders compiled as DXIL, you will need support from the operating system as well as from the driver for your graphics adapter.

At the moment, the Windows 10 Insider Preview Build 15007 is able to run DXIL shaders.

Drivers indicate support DXIL by reporting support for Shader Model 6, possibly in experimental mode. To enable support in these cases, the Developer mode setting must be enabled.

By default, tests will run using the Windows Advanced Rasterization Platform (WARP) adapter. To get the correct version of WARP working, in addition to setting Developer mode, you should install the 'Graphics Tools' optional feature via the Settings app (click the 'Apps' icon, then the 'Manage optional features' link, then 'Add a feature', and select 'Graphics Tools' from the list).

To select the first available adapter that supports D3D12 instead, the parameter /p:"Adapter=*" can be added to the test command line in utils/hct/hcttest.cmd.
