In particular, we wanted to develop a solution to the problem of rendering content that was designed for a higher original target resolution and may not perform out of the box on an integrated GPU. Given the recent adoption of checkerboard rendering for upscaling on the Sony PS4* Pro we thought it would be useful to explore the technique on Intel integrated graphics.

While our focus was on integrated graphics processing units (GPUs), our implementations for both forward and deferred rendering have been tested to run on both AMD and NVIDIA Corporation discrete GPUs. The accompanying sample code demonstrates the technique and provides a base implementation for both forward and deferred rendering pipelines. Finally, we provide areas of future work and next steps. Then we present details of our implementation and results, discussing both performance and quality. Next, we provide an overview of our implementation and some of the issues specific to our solution. In this white paper we discuss our motivation and previous work in the field. Checkerboard rendering is fully compatible with modern post-processing approaches to anti-aliasing and it can be implemented in both forward and deferred rendering pipelines. IntroductionĬheckerboard rendering is a technique that produces full-resolution pixels with a significant reduction in shading and minimal impact on visual quality. The fork includes instructions to build and run a working sample and is available on GitHub* GameTechDev. We have implemented the techniques discussed in this paper into a fork of the DirectX 12 Mini-Engine using Shader Model 5.

Source code to a reference implementation is made available with this article. We believe the relative ease of implementation, scalability across multiple resolutions, and compatibility across graphics processing unit (GPU) vendors make CBR an attractive solution for developers looking to get the most out of their GPU. In our test scene we show an average speed-up with CBR of 1.14x to 1.2x, and as much as 1.4x in frames where pixel shading cost dominates, with minimal impact on the visual quality of the result.

Finally, we include details of how to modify a renderer to support CBR for both a simple forward and deferred rendering case. Next, we build up the motivation for our use of quarter-resolution 2x multi-sampled anti-aliasing (MSAA) render targets and introduce our temporal reconstruction technique. We first review some of the previous work on dynamic real-time upscaling techniques, including publicly available references to the Sony PS4* Pro, the Frostbite engine, and others. In this white paper, we present checkerboard rendering (CBR) for real-time upsampling on Intel integrated graphics.
