4k Checkerboard in Battlefield 1 and Mass Effect Andromeda
Checkerboard rendering is a relatively new technique, popularized recently by the introduction of the PlayStation 4 Pro. Many modern game engines are adding support for it right now, and in this talk, Graham will present an in-depth look at the new implementation in Frostbite, which is used in shipping titles like Battlefield 1 and Mass Effect Andromeda.
Despite being conceptually simple, checkerboard rendering requires a deep integration into the post-processing chain, in particular temporal anti-aliasing, dynamic resolution scaling, and poses various challenges to existing effects.
This presentation will cover the basics of checkerboard rendering, explain the impact on a game engine that powers a wide range of titles, and provide a detailed look at how the current implementation in Frostbite works, including topics like object id, alpha unrolling, gradient adjust, and a highly efficient depth resolve.
