Among the many GDC 2017 presentations, there was a very interesting one which gave an in-depth look at the 4K Checkerboard implementation in the Frostbite engine, which powers many high profile titles published by EA such as Battlefield 1 and the soon to release Mass Effect Andromeda. Most of this presentation has now been made available online.
While a full video is not yet available, the presentation is really interesting as it lets users understand more about this new technique, which has been made more popular following the release of the PlayStation 4 Pro. You can check everything out by going here.
Checkerboard rendering is a technique intended to assist GPUs with rendering images at high resolutions. This technique makes it possible for the PlayStation 4 Pro, which is not powerful enough for native 4K, to achieve this resolution at acceptable frame rates. The latest Sony console comes with specialised hardware which carries out checkerboard rendering with less performance loss.
