Improved Spatial Upscaling through FidelityFX Super Resolution for Real-Time Game Engines

This talk provides in-depth intuition and details about AMD's FSR1 scaling algorithm, as well as shares the architecture behind integrating this technique into Unity's high-definition rendering pipeline. Part of the SIGGRAPH 2021 Advances in Real-Time Rendering in Games course (http://advances.realtimerendering.com/).
All methods shared in the presentation are illustrated with diagrams, images, and performance numbers. First part dives into the details and inner workings of FSR1 scaling algorithm. With a focus on teaching the optimization principles used in its design, and to leave the viewer with some creative thoughts on image processing. Second part covers integration into a modern physically-based deferred and forward rendering pipeline in Unity.
