This session presents an overview of On-Demand Texture streaming technology for Call of Duty, up to and including 2022's Modern Warfare 2. This system significantly reduces the install size of a Call of Duty title while retaining high-quality image quality and low latency multiplayer experience.

Sledgehammer Games' Principal Engineer Chris Fowler goes into how they split texture assets for packaging into the title vs. streaming via CDN, and how they download some content on demand as you encounter it from a CDN near the user.
