C Specification

To retrieve the D3D12 feature level and graphics device for an instance and system, call:

// Provided by XR_KHR_D3D12_enable
XrResult xrGetD3D12GraphicsRequirementsKHR(
    XrInstance                                  instance,
    XrSystemId                                  systemId,
    XrGraphicsRequirementsD3D12KHR*             graphicsRequirements);

Parameters

Parameter Descriptions

Description

The xrGetD3D12GraphicsRequirementsKHR function identifies to the application what graphics device (Windows LUID) needs to be used and the minimum feature level to use. The runtime must return XR_ERROR_GRAPHICS_REQUIREMENTS_CALL_MISSING (XR_ERROR_VALIDATION_FAILURE may be returned due to legacy behavior) on calls to xrCreateSession if xrGetD3D12GraphicsRequirementsKHR has not been called for the same instance and systemId. The LUID and feature level that xrGetD3D12GraphicsRequirementsKHR returns must be used to create the ID3D12Device that the application passes to xrCreateSession in the XrGraphicsBindingD3D12KHR.
