Open Source AMD FidelityFX Super Resolution Impresses In PC Game Tests

MojoKid writes: AMD's FidelityFX Super Resolution (FSR) PC graphics up-scaling technology is ready for prime-time and the company has allowed members of the press to showcase performance and visuals of the tech in action with a number of game engines. AMD FidelityFX Super Resolution is vendor-agnostic and doesn't require specialized hardware to function like NVIDIA DLSS, which relies on Tensor cores on-board NVIDIA Turing or Ampere GPUs to accelerate neural network models that have been specifically trained on game engines. In contrast, AMD FSR utilizes more traditional spatial upscaling to create a super resolution image from a single input frame, not multiple frames. AMD FSR then employs a library of open-source algorithms that work on sharpening both image edge and texture detail. In game testing at HotHardware, frame rates can jump dramatically with little to no perceptible reduction in image quality, and the technology even works on many NVIDIA GPUs as well. There are currently 19 titles that are available or planned with support for AMD FSR, but with the open nature of the technology and cross-GPU compatibility, game developers theoretically should have significant incentive for adoption to breath new performance into their game titles.
