# realtimeGICPUUsage

> How much CPU usage to assign to the final lighting calculations at runtime.

## Definition

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

```csharp
public static int realtimeGICPUUsage { get; set; }
```

### Remarks

Increase the CPU Usage setting for Realtime GI in the Quality Settings window. If you dedicate more CPU time, then the runtime lighting converges faster. This means that other systems receive less CPU time to do their work.
