Low-Level Shader Optimization for Next-Gen and DX11

Emil Persson  |  Head of Research, Avalanche Studios

Location: Room 304, South Hall

Format: Session
Track: Programming
Vault Recording: Video

This lecture will go through examples to show how high-level shading constructs map to the underlying hardware assembly instructions, as well as intrinsics for accessing special GPU instruction. Modern shader features such as integer math, doubles, branching and compute will be discussed. Numerous low-level optimization tricks will be covered, illustrating the benefits of a close-to-the-metal mindset while writing shaders in high-level languages. The main focus is on GCN, the GPU architecture powering next-gen consoles, as well as recent AMD GPUs for PC, but generic optimizations applicable to any modern GPU will also be discussed.


Attendees will gain a deeper understanding of the GCN architecture and how high-level shading language constructs map to actual hardware shader instructions. They will leave better equipped to write high performance shaders for next-gen consoles and PCs.

Intended Audience

This session is aimed at graphics programmers and shader writers, both experienced professionals and beginners. Basic understanding of HLSL or other shading languages is required.
