AMD’s Answer to DLSS: How FSR Works

This video explains AMD FidelityFX Super Resolution, or FSR, and how it stacks up against Nvidia's DLSS. It starts by outlining the core idea behind FSR: render a game at a lower resolution and upscale to the display resolution to boost frame rates. The discussion traces the evolution of FSR through its revisions, highlighting FSR 1’s edge reconstruction, FSR 2’s temporal upscaling that leverages data from previous frames, and the arrival of FSR 3 which adds frame generation and native anti-aliasing options. The host compares FSR 2 and DLSS in terms of image quality, latency implications, and the reliance on developer support for broad adoption, noting that FSR 3 can introduce input latency in some scenarios and may vary by title. In practical terms, enabling FSR in games involves toggling settings, with FSR 3 offering a blend of frame generation and upscaling that can coexist with other upscalers like DLSS, depending on the game and hardware. The video also mentions AMD’s Radon Super Resolution as a more universal solution for exclusive fullscreen games, requiring an AMD RX 5000 series GPU or newer. Overall, the takeaway is that FSR provides a capable, open alternative to DLSS with varying results across games, and it continues to evolve with each revision to improve performance and visual fidelity.
