> A multiplier that Unity applies to the delta time when it updates the VisualEffect. The default value is 1.0f.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine.VFX](/engine/6000.7/script-reference/unityengine/vfx.md)
* **Assembly:** UnityEngine.VFXModule

```csharp
public float playRate { get; set; }
```

### Remarks

To play the visual effect faster than normal, set this property to a value greater than 1.0f. To play the visual effect slower than normal, set this property to a value between 0.0f and 1.0f. Unity does not serialize this property. This means that, after loading, it automatically resets to the default value.
