Advanced Visual Effects with DirectX 11: Vertex Shader Tricks - New Ways to Use the Vertex Shader to Improve Performance

Bill Bilodeau  |  Developer Technology Engineer, AMD

Location: Room 2006, West Hall

Format: Tutorials & Bootcamps
Track: Programming
Vault Recording: Video

The vertex shader is often overlooked when trying to improve performance, thinking it should only be used for basic vertex transformations. DirectX, however, allows for a lot of flexibility in how vertices are passed to the vertex shader, which enables techniques like vertex shader instancing. This talk will explain some of the ways that the vertex shader can be used to improve performance by taking a fast path through the vertex shader, rather than generating vertices with other parts of the pipeline. The talk will include sample code and performance statistics with current generation GPUs.


Attendees will gain greater insights into advanced utilization of the Direct3D 11 graphics API, as used for high-end techniques in popular, AAA-shipping titles.

Intended Audience

The intended audience for this session includes graphics programmers who are planning or actively developing a cutting-edge Direct3D 11 application.
