This session is divided into three main sections. First, we will introduce the new DX12 Ultimate Variable Rate Shading API including a summary of recent titles and literature that have taken advantage of Variable Rate Shading both Tier 1 and Tier 2. Second, inspired by research literature in the field, we will share details of our implementation and optimization of a content and motion-adaptive error metric as a demonstration in the Microsoft DIrectX12 MiniEngine. Finally, we discuss the performance and quality tradeoffs of our implementation and share details on how to get access to our implementation.


Attendees will walk away with an understanding of the DX12 Variable Rate Shading API, Intel's Alchemist GPU capabilities with respect to this API, and understand how to implement a content-adaptive variable-rate shading technique that uses the VRS Tier 2 API to control the shading rate of an image

Intended Audience

The intended audience has an intermediate familiarity with 3D APIs but may not yet be familiar with the concept of variable rate shading. Familiarity with DirectX is desirable but not required.
