Coming to DirectX 12: More control over memory allocation

Alma Haage (Red Door Collaborative LLC)

In the next update to Windows, D3D12 will be adding two new flags to the D3D12_HEAP_FLAG enumeration. These new flags are “impermanent” properties, which don’t affect the resulting memory itself, but rather the way in which it’s allocated. As such, it’s important to call out that these flags aren’t reflected from ID3D12Heap::GetDesc or ID3D12Resource::GetHeapProperties. Let’s dive in.
