Microsoft Agility SDK 1.613.0: Work Graphs and Shader Model 6.8

Introduction

Microsoft’s Agility SDK 1.613.0 brings exciting enhancements to game development, empowering developers with cutting-edge features. In this comprehensive blog post, we’ll delve into the latest updates, focusing on Work Graphs and Shader Model 6.8. Buckle up for a journey through the realms of GPU optimization and shader development!

Work Graphs: A Paradigm Shift

• What are Work Graphs?

  • Work Graphs revolutionize GPU utilization by enabling dynamic, on-the-fly scheduling of GPU workloads.
  • Unlike traditional models, Work Graphs empower developers to generate and schedule GPU work independently, without relying on the host.
  • Benefits: Higher performance, lower latency, and scalability for tasks like culling, binning, and compute work.

• How Does It Work?

  • Developers can create and manage GPU work nodes within the Work Graph.
  • Tasks are scheduled dynamically, allowing for efficient parallel execution.
  • Work Graphs enhance flexibility, creativity, and efficiency in game development.

• Partner Perspectives

  • AMD and NVIDIA both offer day-one driver support for Work Graphs.
  • Their blog posts provide additional insights and use cases.

Shader Model 6.8: Unleashing Creativity

• Start Vertex/Instance Location

  • New system values (SV_StartVertexLocation and SV_StartInstanceLocation) allow shaders to examine parameters from the invoking Draw*Instanced() API call.
  • Useful for custom address calculations independent of fixed function data.

• Wave Size Range

  • Developers can specify preferred wave sizes (MIN, MAX, PREFERRED) directly in shaders.
  • Reduces the need for multiple shaders with different wave sizes.
  • Enables drivers to choose suitable wave sizes per shader.

• Expanded Comparison Sampling

  • All pixel sampling methods now available for sample comparison objects.
  • Create better cross-platform shaders with enhanced sampling options.
