AMD opens source code for FidelityFX Super Resolution - smart scaling available to all

AMD has kept its promise and made its FidelityFX Super Resolution (FSR) smart scaling technology an open source solution. All required documentation and samples of FSR are now available for download from the GPU Open website. In addition, the company announced that FSR support appeared in four new games: Arcadegeddon, Necromunda Hired Gun, Edge of Eternity and Resident Evil Village.

AMD calls FSR technology a "practical gas pedal" of resource-intensive rendering operations, such as the same ray tracing in real time, capable of improving performance in games, even on entry-level graphics cards. But only in those game projects where its support is declared. Unlike NVIDIA, which closed its DLSS smart scaling technology, AMD has decided to make FSR available to as many game developers as possible by opening its source code. The code itself integrates easily into any project and is supported by multiple platforms. AMD gave access to different graphics API settings, for example for DirectX 12 and Vulkan, and also promised to make FSR compatible with DirectX 11. Unlike DLSS, FSR technology does not rely on special processing units of AI tasks, so it does not require tensor cores to work. AMD is betting on the simplicity and rapid integration of FSR. The published AMD documentation contains information about all available FSR settings, input and output resolution scaling levels and other aspects describing the features of the technology. Also, the situation with FSR support on old video cards, about which nothing was initially mentioned, was clarified. For older GPUs (before Vega generation), the FSR technology uses a special mode based on half-precision calculation algorithm (FP16). On more modern graphics cards, such as the Radeon RX 400 and newer, as well as the GeForce 900-series and newer, FSR relies on an algorithm using single-precision computation (FP32). It is not yet clear whether this difference will be noticeable to the user or if it is there at all. The company also announced that the popular Unity game engine will get FSR support in the next version (2021.2b).
