# SynchronisationStageFlags

> Describes the various stages of GPU processing against which the GraphicsFence can be set and waited against.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEngine.Rendering](/engine/6000.7/script-reference/unityengine/rendering.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public enum SynchronisationStageFlags
```

## Remarks

The enum values can be combined; for example, a GraphicsFence created with SynchronisationStageFlags.VertexProcessing | SynchronisationStageFlags.ComputeProcessing flags would complete once all previous draw calls have completed their vertex shaders and all previous compute shader dispatches have completed.
