Member Data Documentation

AdapterIndex

int32 FD3D12AdapterDesc::AdapterIndex = -1

-1 if not supported or FindAdapter() wasn't called. Ideally we would store a pointer to IDXGIAdapter but it's unlikely the adpaters change during engine init.

bSupportsAtomic64

bool FD3D12AdapterDesc::bSupportsAtomic64 = false

Whether SM6.6 atomic64 wave ops are supported

bSupportsWaveOps

bool FD3D12AdapterDesc::bSupportsWaveOps = false

Whether SM6.0 wave ops are supported

bUMA

bool FD3D12AdapterDesc::bUMA = false

Whether the GPU has unified memory. This can be used to identify integrated GPU as well.

Desc

DXGI_ADAPTER_DESC FD3D12AdapterDesc::Desc {}

MaxRHIFeatureLevel

ERHIFeatureLevel::Type FD3D12AdapterDesc::MaxRHIFeatureLevel = ERHIFeatureLevel::Num

MaxSupportedFeatureLevel

D3D_FEATURE_LEVEL FD3D12AdapterDesc::MaxSupportedFeatureLevel = (D3D_FEATURE_LEVEL)0

The maximum D3D12 feature level supported. 0 if not supported or FindAdapter() wasn't called

MaxSupportedShaderModel

D3D_SHADER_MODEL FD3D12AdapterDesc::MaxSupportedShaderModel = (D3D_SHADER_MODEL)0

The maximum Shader Model supported. 0 if not supported or FindAdpater() wasn't called

NumDeviceNodes

uint32 FD3D12AdapterDesc::NumDeviceNodes = 1

Number of device nodes (read: GPUs)

ResourceBindingTier

D3D12_RESOURCE_BINDING_TIER FD3D12AdapterDesc::ResourceBindingTier = D3D12_RESOURCE_BINDING_TIER_1

ResourceHeapTier

D3D12_RESOURCE_HEAP_TIER FD3D12AdapterDesc::ResourceHeapTier = D3D12_RESOURCE_HEAP_TIER_1
