Spatial-Temporal Post-processing

URP only. Software-based Upscaler (also can downscale but meaningless).

Official

Unity Document: <here>

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.

Works on URP 3D Project only.
