I've uploaded a few of the (public) external presentations that I've done the last couple of years. Planning a new talk for GDC this year (focused on DX10/11 rendering) and hopefully another one for the Siggraph real-time rendering course as well, should be interesting as always!
The Intersection of Game Engines & GPUs: Current & Future (Graphics Hardware 2008)
Terrain Rendering in Frostbite using Procedural Shader Splatting (Siggraph 2007)
Don't miss the course notes for Siggraph course.
Frostbite Rendering Architecture and Real-time Procedural Shading & Texturing Techniques (GDC 07)
