[PS4 Pro’s Checkerboard rendering is] a cute trick that fell out of the temporal anti-aliasing line of thinking,” he said. “Like TAA it requires a big investment in a specific direction for your engine architecture: you need per-pixel velocity vectors, fallback strategies for the myriad effects that don’t fit that design, well-designed reprojection systems and game systems that are aware of single-frame effect limitations. If you’ve already invested in TAA then it could be a lot easier for you to integrate but there are strains of developers who don’t believe betting the farm on TAA is wise: you end up building a significant amount of code that stops working the minute you turn TAA off.
