Session Name:

Cross-Platform Determinism in 'Warhammer Age of Sigmar: Realms of Ruin'


In this session, learn how and why Frontier Developments built a new deterministic simulation framework that underpins everything players see and interact with in Warhammer Age of Sigmar: Realms of Ruin. Engineering Lead Bradley Pollard covers the journey taken by the development teamfrom implementing a thread-safe ECS to creating tooling to analyze and prevent desynchronizations. Learn how determinism benefits both the developers, as well as the game, by enabling reproducibility, providing low-cost networking, and even providing a form of anti-cheat. The talk also addresses how Frontier was able to create a framework that is able to run on PC, Xbox, PlayStation, and Linux, and ensure determinism.
