# SetQualityLevel

> Sets a new graphics quality level.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine](/engine/6000.6/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

## SetQualityLevel(int)

Sets a new graphics quality level.

```csharp
public static void SetQualityLevel(int index)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): Quality index to set.

### Remarks

The list of quality levels can be found by going to **Edit** > **Project Settings** > **Quality**. You can add, remove or edit these.

```csharp
using UnityEngine;

public class Example : MonoBehaviour
{
    void OnGUI()
    {
        string[] names = QualitySettings.names;
        GUILayout.BeginVertical();
        for (int i = 0; i < names.Length; i++)
        {
            if (GUILayout.Button(names[i]))
            {
                QualitySettings.SetQualityLevel(i, true);
            }
        }
        GUILayout.EndVertical();
    }
}
```

Note that changing the quality level can be an expensive operation if the new level has different anti-aliasing setting. It's fine to change the level when applying in-game quality options, but if you want to dynamically adjust quality level at runtime, pass false to applyExpensiveChanges so that expensive changes are not always applied.

When building a player quality levels that are not used for that platform are stripped. You should not expect a given quality setting to be at a given index. It's best to query the available quality settings and use the returned index.

## SetQualityLevel(int, bool)

Sets a new graphics quality level.

```csharp
public static void SetQualityLevel(int index, bool applyExpensiveChanges)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): Quality index to set.**** (\[bool]\(https\://learn.microsoft.com/dotnet/api/system.boolean)): Should expensive changes be applied (Anti-aliasing etc).

### Remarks

The list of quality levels can be found by going to **Edit** > **Project Settings** > **Quality**. You can add, remove or edit these.

```csharp
using UnityEngine;

public class Example : MonoBehaviour
{
    void OnGUI()
    {
        string[] names = QualitySettings.names;
        GUILayout.BeginVertical();
        for (int i = 0; i < names.Length; i++)
        {
            if (GUILayout.Button(names[i]))
            {
                QualitySettings.SetQualityLevel(i, true);
            }
        }
        GUILayout.EndVertical();
    }
}
