![]() ![]() Versions of Direct3D built into the operating system at or before Manganese (20H2) use 3DPIPELINESUPPORT.The driver returns a value for MaximumDriverSupportedFeatureLevel which does not exceed HighestRuntimeSupportedFeatureLevel. Typedef struct D3D12DDI_3DPIPELINESUPPORT1_DATA_0081ĭ3D12DDI_3DPIPELINELEVEL HighestRuntimeSupportedFeatureLevel // inputĭ3D12DDI_3DPIPELINELEVEL MaximumDriverSupportedFeatureLevel // outputįor 3DPIPELINESUPPORT1, the runtime sets the value of HighestRuntimeSupportedFeatureLevel. ![]() This enumeration has a value for feature level 12.2: The Direct3D 12 UMD DDI has an enumeration, D3D12DDI_3DPIPELINELEVEL, for describing feature levels. Some specifications, especially those from before the May 2019 Update, are not migrated to the DirectX-Specs repo. VPAndRTArrayIndexFromAnyShaderFeedingRasterizerSupportWithoutGSEmulation There are no guarantees in particular regarding MaxGPUVirtualAddressBitsPerResource and MaxGPUVirtualAddressBitsPerProcess for 32-bit processes.Īdditionally, it has the following flags set Feature This idea pertains to process architecture which is not necessarily the same as CPU or operating system architecture. On feature level 12_2 devices, the two capabilities MaxGPUVirtualAddressBitsPerResource and MaxGPUVirtualAddressBitsPerProcess are guaranteed to be at least 40 for programs running in 64-bit processes (for example, 圆4-based processes are considered 64-bit processes). If a device is feature level 12_2, it has Feature feature level is supported by default adapterįeature level 12_2 is expressed in terms of capabilities and feature tiers directly queryable through CheckFeatureSupport. HRESULT hr = D3D12CreateDevice(nullptr, featureLevel, IID_PPV_ARGS(&m_spDevice)) D3D_FEATURE_LEVEL featureLevel = D3D_FEATURE_LEVEL_12_2 ![]()
