Advanced Micro Devices (AMD) officially disclosed technical specifications for a new iteration of its FidelityFX Super Resolution (FSR) technology on April 21, 2026. The update, published via the company’s GPUOpen open-source platform, introduces a feature titled Multi-Frame Generation. This development marks a shift from the industry-standard dual-frame interpolation toward a more aggressive scaling model that allows for the insertion of multiple synthetic frames between traditionally rendered ones.
The core of the announcement centers on the introduction of a Frame Generation Upgrade Ratio parameter within the FSR API. According to the technical documentation released by AMD, this setting enables developers to select interpolation ratios beyond the standard 2x output. The documentation specifically highlights the capability for 3x and 4x frame generation, which would theoretically allow a base frame rate of 30 frames per second (FPS) to be displayed at 90 or 120 FPS through the generation of two or three intermediate frames for every one rendered by the graphics processing unit (GPU).
AMD’s implementation of Multi-Frame Generation is designed to function as an evolution of the existing FSR 3 and FSR 3.1 architectures. The company stated that the new system utilizes enhanced optical flow vectors and temporal data to maintain visual fidelity when generating consecutive synthetic frames. While previous versions of frame generation technology were largely limited to a 1:1 ratio of real to generated frames to minimize latency and visual artifacts, AMD’s new documentation suggests that improvements in its asynchronous compute workloads have mitigated some of these historical constraints.
The release on GPUOpen confirms that the technology will remain part of AMD’s commitment to open-source software standards. This ensures that Multi-Frame Generation will be compatible with a broad range of hardware, including older AMD Radeon GPUs, as well as competing products from Nvidia and Intel, provided they meet the minimum asynchronous compute requirements. AMD has not yet provided a definitive list of initial game titles that will support the 3x and 4x ratios, but the company indicated that the SDK (Software Development Kit) is now available for integration by licensed developers.
Technical leads at AMD noted in the GPUOpen update that the Multi-Frame Generation feature includes a new Interpolation Quality Guard. This sub-routine is designed to dynamically adjust the generation ratio based on real-time motion complexity to prevent ghosting or shimmering effects that can occur during high-velocity scenes. The company also detailed a revised version of its Anti-Lag+ technology, which is intended to be paired with the multi-frame output to manage the increased input latency inherent in high-ratio interpolation.
