> Defines constants that specify heap serialization support.

Defines constants that specify heap serialization support.

## Syntax

```cpp theme={null}
typedef enum D3D12_HEAP_SERIALIZATION_TIER
{
    D3D12_HEAP_SERIALIZATION_TIER_0 (0) = 0,
    D3D12_HEAP_SERIALIZATION_TIER_10 (10) = 0
} D3D12_HEAP_SERIALIZATION_TIER
```

## Constants

| Constant                                  | Description                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            |

| D3D12\_HEAP\_SERIALIZATION\_TIER\_0 (0)   | Indicates that heap serialization is not supported.                                                                                                                                                                                                                                                                                                                                                                                                                                                                    |
| D3D12\_HEAP\_SERIALIZATION\_TIER\_10 (10) | Indicates that heap serialization is supported. Your application can serialize resource data in heaps through copying APIs such as [CopyResource](https://learn.microsoft.com/en-us/windows/win32/api/d3d12/nf-d3d12-id3d12graphicscommandlist-copyresource), without necessarily requiring an explicit [state transition](https://learn.microsoft.com/en-us/windows/desktop/direct3d12/using-resource-barriers-to-synchronize-resource-states-in-direct3d-12#implicit-state-transitions) of resources on those heaps. |

## Remarks

**Header:** d3d12\_xs.h or d3d12\_x.h<br />**Library:** d3d12\_xs.lib or d3d12\_x.lib<br />**Supported Platforms**: XBOX Series consoles and XBOX One family
