# D3D12_SHADER_MIN_PRECISION_SUPPORT

> Describes minimum precision support options for shaders in the current graphics driver.

Describes minimum precision support options for shaders in the current graphics driver.

## Syntax

```cpp theme={null}
typedef enum D3D12_SHADER_MIN_PRECISION_SUPPORT
{
    D3D12_SHADER_MIN_PRECISION_SUPPORT_NONE = 0,
    D3D12_SHADER_MIN_PRECISION_SUPPORT_10_BIT = 1,
    D3D12_SHADER_MIN_PRECISION_SUPPORT_16_BIT = 2
} D3D12_SHADER_MIN_PRECISION_SUPPORT
```

## Constants

| Constant                                        | Description                                                           |
| ----------------------------------------------- | --------------------------------------------------------------------- |
| D3D12\_SHADER\_MIN\_PRECISION\_SUPPORT\_NONE    | The driver supports only full 32-bit precision for all shader stages. |
| D3D12\_SHADER\_MIN\_PRECISION\_SUPPORT\_10\_BIT | The driver supports 10-bit precision.                                 |
| D3D12\_SHADER\_MIN\_PRECISION\_SUPPORT\_16\_BIT | The driver supports 16-bit precision.                                 |

## Remarks

This enum is used by the [D3D12\_FEATURE\_DATA\_D3D12\_OPTIONS](/reference/graphics/d3d12/structs/d3d12_feature_data_d3d12_options_public) structure.

The returned info just indicates that the graphics hardware can perform HLSL operations at a lower precision than the standard 32-bit float precision, but doesn't guarantee that the graphics hardware will actually run at a lower precision.

## 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
