Provides detail about whether the adapter supports creating heaps from existing system memory. Such heaps are not intended for general use, but are exceptionally useful for diagnostic purposes, because they are guaranteed to persist even after the adapter faults or experiences a device-removal event. Persistence is not guaranteed for heaps returned by ID3D12Device::CreateHeap or ID3D12Device::CreateCommittedResource, even when the heap resides in system memory.

​
Syntax

​
Members

Supported
Type: BOOL TRUE if the adapter can create a heap from existing system memory. Otherwise, FALSE.

​
Remarks

For a variety of performance and compatibility reasons, applications should not make use of this feature except for diagnostic purposes. In particular, heaps created using this feature only support system-memory heaps with cross-adapter properties, which precludes many optimization opportunities that typical application scenarios could otherwise take advantage of.

​
Requirements

Header: d3d12_xs.h or d3d12_x.h
Library: d3d12_xs.lib or d3d12_x.lib
Supported Platforms: XBOX Series consoles and XBOX One family
