DetailedStatistics D3D12MA::TotalStatistics::HeapType[5]

One element for each type of heap located at the following indices:

DetailedStatistics D3D12MA::TotalStatistics::MemorySegmentGroup[2]

One element for each memory segment group located at the following indices:

Meaning of these segment groups is:

When IsUMA() == FALSE (discrete graphics card):
- DXGI_MEMORY_SEGMENT_GROUP_LOCAL (index 0) represents GPU memory (resources allocated in D3D12_HEAP_TYPE_DEFAULT, D3D12_HEAP_TYPE_GPU_UPLOAD or D3D12_MEMORY_POOL_L1).
- DXGI_MEMORY_SEGMENT_GROUP_NON_LOCAL (index 1) represents system memory (resources allocated in D3D12_HEAP_TYPE_UPLOAD, D3D12_HEAP_TYPE_READBACK, or D3D12_MEMORY_POOL_L0).
When IsUMA() == TRUE (integrated graphics chip):
- DXGI_MEMORY_SEGMENT_GROUP_LOCAL = (index 0) represents memory shared for all the resources.
- DXGI_MEMORY_SEGMENT_GROUP_NON_LOCAL = (index 1) is unused and always 0.

DetailedStatistics D3D12MA::TotalStatistics::Total
