public static void SetQualityLevel (int index, bool applyExpensiveChanges= true);

Parameters

indexQuality index to set.
applyExpensiveChangesShould expensive changes be applied (Anti-aliasing etc).

Description

Sets a new graphics quality level.

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

no example available in C#

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 adjustquality 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.
