Variable Rate Shading in Direct3D 12
« on: March 25, 2019, 07:13:55 PM »
This document describes Direct3D 12 exposure of graphics hardware functionality.

Due to performance constraints, graphics renderers cannot always afford to deliver the same quality level on every part of their output image. Variable rate shading, or coarse pixel shading, is a mechanism to enable allocation of rendering performance/power at varying rates across the rendered image.

Visually, there are cases where shading rate can be reduced with little or no reduction in perceptible output quality, leading to “free” performance.
