DICE Devs On PS4 Pro: Proper Checkerboard Implementation Is Complex, EQAA Can Bring Great Savings

A lot has been said about the PlayStation 4 Pro and the custom technique developers can use to achieve "4K" resolution. The technique is called checkerboard rendering and its has been used in several PlayStation 4 games such as the recently released Horizon Zero Dawn to achieve a 2160p checkerboard resolution. To make it simple to understand, checkerboard 4K resolution isn't native 4K resolution. It's a process of using a complex pixel algorithm to generate an image that resembles a 4K image buffer but in reality it isn't. However it's isn't a mere upscale either.
