# D3D12_RAYTRACING_TIER

> Specifies the level of ray tracing support on the graphics device.

Specifies the level of ray tracing support on the graphics device.

## Syntax

```cpp theme={null}
typedef enum D3D12_RAYTRACING_TIER
{
    D3D12_RAYTRACING_TIER_NOT_SUPPORTED = 0,
    D3D12_RAYTRACING_TIER_1_0 = 10
} D3D12_RAYTRACING_TIER
```

## Constants

| Constant                                | Description                                                                                                                                                                                |
| --------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| D3D12\_RAYTRACING\_TIER\_NOT\_SUPPORTED | No support for ray tracing on the device.  Attempts to create any ray tracing-related object will fail, and using ray tracing-related APIs on command lists results in undefined behavior. |
| D3D12\_RAYTRACING\_TIER\_1\_0           | The device supports tier 1 ray tracing functionality. In the current release, this tier represents all available ray tracing features.                                                     |

## Remarks

To determine the supported ray tracing tier for a graphics device, pass [D3D12\_FEATURE\_DATA\_D3D12\_OPTIONS5](/reference/graphics/d3d12/structs/d3d12_feature_data_d3d12_options5_public) struct.

## 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
