AMD has updated its official product page to refer to its advanced upscaling technology simply as FSR, noting that FSR stands for “formerly AMD FidelityFX Super Resolution.” The change was made on the product page and so far has not been accompanied by any formal announcement from the company. Observers and the report note the move is sudden and unusual for a branded technology that has been marketed under the full FidelityFX Super Resolution name.
The rebrand appears ahead of an FSR “Redstone” product demo scheduled for December 10, which AMD says will include technical details about the new platform and the games that will implement it. According to the product copy cited in the article, FSR Redstone builds on the Artificial Intelligence and machine learning super resolution work introduced with FSR 4 and will introduce three primary innovations: neural radiance caching, Artificial Intelligence and machine learning-based ray regeneration, and Artificial Intelligence and machine learning-based frame generation. The demo is expected to show how those systems operate and which titles will integrate the new techniques.
The report highlights neural radiance caching as a key feature, describing it as a machine learning model that continuously learns how light interacts within a scene to predict and store indirect lighting, with the aim of reducing the performance cost of ray tracing. The article also suggests the shorter FSR acronym may be intended to resonate more readily with the gaming audience, drawing a parallel to AMD itself, which is an acronym for Advanced Micro Devices. For now the change is visible on AMD’s page but remains undocumented in any official press release or broader messaging from the company.
