The **Anti-aliasing** effect softens the appearance of edges in your scene. To do this, it surrounds the edge with similar points of color. This reduces the jagged effect caused by [aliasing](https://en.wikipedia.org/wiki/Aliasing).
The Post-processing anti-aliasing algorithms are image-based, which is useful when support for traditional multisampling is not available, such as the [deferred rendering](https://docs.unity3d.com/Manual/RenderTech-DeferredShading.html) path. You can configure the rendering settings in the [Quality settings](https://docs.unity3d.com/Manual/class-QualitySettings.html) window.
