## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public static float fixedUnscaledDeltaTime { get; }
```

### Remarks

Unlike [Time.fixedDeltaTime](/engine/6000.0/script-reference/unityengine/time/fixeddeltatime.md) this value is in real time rather than scaled game-time and therefore not affected by [Time.timeScale](/engine/6000.0/script-reference/unityengine/time/timescale.md).
