https://wccftech.com/no-amds-fsr-fidelityfx-super-resolution-is-not-a-dlss-alternative-and-here-is-why-you-should-care/ > AMD recently rolled out an amazing new framework called FidelityFX Super Resolution (FSR) and in a stroke of genius and commitment to open standards, made it available for both Radeon and GeForce GPUs (editor's note: see the update at the end of the article). While the feature will certainly help breathe new life into older GPUs, it is not a DLSS alternative and cannot be - any attempt to hype it up as a DLSS competitor would hurt the brand more than it helps. I expect a lot of pushback on this article but it is important that AMD fans understand the facts of the comparison so they can call on AMD to deliver a true DLSS competitor eventually (bonus points if that is open source as well). > Headlines like AMD's answer to DLSS works on all GPUs are currently everywhere - but there is one critical flaw - FSR and DLSS are not alike. While NVIDIA DLSS is an upscaling system based on Deep Learning/Inference and uses actual hardware to enable performance enhancement without any serious quality degradation - FSR is just a simple spatial upscale. The two classes of upscale are not even remotely comparable and is like resizing something in photoshop versus resizing something in Gigapixel AI. The latter is a far superior result.
