# useDirect3D11

> Should Direct3D 11 be used when available?

## Definition

* **Type:** Property
* **Namespace:** [UnityEditor](/engine/6000.0/script-reference/unityeditor.md)
* **Assembly:** UnityEditor

> **Warning:**
>
> **Deprecated.** Use UnityEditor.PlayerSettings.SetGraphicsAPIs/GetGraphicsAPIs instead

```csharp
public static bool useDirect3D11 { get; set; }
```

### Remarks

Using DX11 enables more modern graphics features, like [Compute Shaders](/engine/6000.0/manual/materials-and-shaders/shaders/writing-custom/class-compute-shader.md), tessellation shaders and other shader model 4.0-5.0 features.

This flag is specific to Windows Editor, Standalone and Web Player builds.

When set to true, Unity will try to use the Direct3D 11 graphics API (which works on Windows Vista or later OS, and DX10+ level GPU). If that is not available (e.g. DX9 level GPU or Windows XP), Direct3D 9 will be used instead.

When set to false, Direct3D 9 API will be used.
