# D3D12_SERIALIZED_DATA_DRIVER_MATCHING_IDENTIFIER

> Opaque data structure describing driver versioning for a serialized acceleration structure.

Opaque data structure describing driver versioning for a serialized acceleration structure.  Pass this structure into a call to [ID3D12Device5::CheckDriverMatchingIdentifier](/reference/graphics/d3d12/interfaces/id3d12device5/methods/id3d12device5_checkdrivermatchingidentifier_public) to determine if a previously serialized acceleration structure is compatible with the current driver/device, and can therefore be deserialized and used for raytracing.

## Syntax

```cpp theme={null}
typedef struct D3D12_SERIALIZED_DATA_DRIVER_MATCHING_IDENTIFIER
{
    GUID DriverOpaqueGUID;
    BYTE DriverOpaqueVersioningData;
} D3D12_SERIALIZED_DATA_DRIVER_MATCHING_IDENTIFIER
```

### Members

*DriverOpaqueGUID*\
Type: GUID

The opaque identifier of the driver.

*DriverOpaqueVersioningData*\
Type: BYTE\[16]

The opaque driver versioning data.

## 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
