# Spatial-Temporal Post-processing

### Official

Unity Document: <[here](https://docs.unity3d.com/6000.0/Documentation/Manual/urp/stp/stp-upscaler.html)>

### Purpose

As this is a post-processing, nothing will be changed on the rendering processes.  The main purpose of STP is to upscale low resolution content to hight resolution content.

If your project is meeting a rendering performance issue and scene contents cannot be optimized anymore, you can set a low resolution to render the scene contents.  STP can upscale your low resolution output to high resolution.

{% hint style="warning" %}
Works on URP 3D Project only.
