# Optimize GPU performance with variable rate shading

> Implement variable rate shading to reduce GPU workload while maintaining visual quality in critical screen areas.

Implement variable rate shading (VRS) to optimize rendering performance while maintaining visual quality where it matters most.

Refer to the following topics to understand variable rate shading and how to implement it.
