Member Data Documentation

◆ m_descriptorHeapLimits

AZStd::unordered_map<AZStd::string, AZStd::array<uint32_t, NumHeapFlags> > AZ::DX12::PlatformLimitsDescriptor::m_descriptorHeapLimits

string key: string version of DESCRIPTOR_HEAP_TYPE. int array: Max count for descriptors

◆ m_staticDescriptorRatio

float AZ::DX12::PlatformLimitsDescriptor::m_staticDescriptorRatio = 0.5f

Denote portion of the shader-visible descriptor heap used to maintain static handles. NOTE: dynamic descriptors are needed to allocate per-frame descriptor tables for resources that are not bound via bindless, so this number should reflect that. If the majority of resources correctly leverage the bindless mechanism, this number can be higher (e.g. [0.8f, 0.9f]).
