# D3D12_FEATURE_DATA_D3D12_OPTIONS6

> Indicates the level of support that the adapter provides for variable-rate shading (VRS), and indicates whether or not background processing is supported.

Indicates the level of support that the adapter provides for variable-rate shading (VRS), and indicates whether or not background processing is supported. For more info, see [Variable-rate shading (VRS)](https://learn.microsoft.com/en-us/windows/desktop/direct3d12/vrs), and the [Direct3D 12 background processing spec](https://microsoft.github.io/DirectX-Specs/d3d/BackgroundProcessing.html).

## Syntax

```cpp theme={null}
typedef struct D3D12_FEATURE_DATA_D3D12_OPTIONS6
{
    BOOL AdditionalShadingRatesSupported;
    BOOL PerPrimitiveShadingRateSupportedWithViewportIndexing;
    D3D12_VARIABLE_SHADING_RATE_TIER VariableShadingRateTier;
    UINT ShadingRateImageTileSize;
    BOOL BackgroundProcessingSupported;
} D3D12_FEATURE_DATA_D3D12_OPTIONS6
```

### Members

*AdditionalShadingRatesSupported*\
Type: BOOL

Indicates whether 2x4, 4x2, and 4x4 coarse pixel sizes are supported for single-sampled rendering; and whether coarse pixel size 2x4 is supported for 2x MSAA. `true` if those sizes are supported, otherwise `false`.

*PerPrimitiveShadingRateSupportedWithViewportIndexing*\
Type: BOOL

Indicates whether the per-provoking-vertex (also known as per-primitive) rate can be used with more than one viewport. If so, then, in that case, that rate can be used when `SV_ViewportIndex` is written to. `true` if that rate can be used with more than one viewport, otherwise `false`.

*VariableShadingRateTier*\
Type: D3D12\_VARIABLE\_SHADING\_RATE\_TIER

Indicates the shading rate tier.

*ShadingRateImageTileSize*\
Type: UINT

Indicates the tile size of the screen-space image as a **UINT**.

*BackgroundProcessingSupported*\
Type: BOOL

Indicates whether or not background processing is supported. `true` if background processing is supported, otherwise `false`. For more info, see the [Direct3D 12 background processing spec](https://microsoft.github.io/DirectX-Specs/d3d/BackgroundProcessing.html).

## Remarks

## 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
