RSR
Radeon Super Resolution (RSR) is an in-driver upscaling feature that uses the same algorithm found in our AMD FidelityFX Super Resolution (FSR) technology. RSR works by upscaling lower resolutions set in-game to the native resolution of the active display, providing higher FPS performance.
RSR can be configured globally so the effects will be applied to all compatible games. It can also be separately customized for individual games using AMD Software application profiles.
