AMD FidelityFX™ SDK v2
AMD FidelityFX™ SDK v2 is the launchpad for our ML-based rendering technologies, inc. AMD FSR 4 and upcoming FSR Redstone features.
The AMD FidelityFX™ Super Resolution 4 (FSR 4) plugin has been updated for Unreal® Engine 5.7, bringing developers and players an even more immersive experience on AMD RDNA™ 4 architecture graphics (AMD Radeon™ RX 9000 series). Designed to help improve temporal stability, better preserve detail, and reduce ghosting, AMD FSR 4 ensures your world looks stunning while maintaining exceptional performance.
This update continues AMD’s commitment to make integration and updates simple for developers. By leveraging the AMD FidelityFX API introduced in AMD FSR 3.1, developers have an easy upgrade path. Future AMD Software: Adrenalin Edition™ releases will automatically update the version of FSR 4 Upscaling used in-game to the latest available without requiring manual updates for each title. This ensures players experience the highest quality upscaling without requiring frequent game-side updates for each title.
The plugin also provides a fallback to AMD FSR 3.1.5 analytic upscaling when your game is running on AMD RDNA™ 3.5 architecture and lower graphics cards. It also includes analytical frame generation compatible with AMD Radeon RX 5000 series (AMD RDNA 1 architecture) and newer graphics cards to deliver a significant increase in framerates in supported games. Additionally, integrating FSR 3.1.5 analytical frame generation adds the required camera parameters to support ML frame generation automatically via our driver upgrade feature. This upcoming feature is part of FSR “Redstone” coming later this year.
In addition to updating the AMD FSR 4 plugin, the AMD Radeon™ Anti-Lag 2 plugin will soon be updated to support Unreal Engine 5.7. Radeon Anti-Lag 2 enables games to reduce end-to-end system latency in GPU-bound scenarios on AMD Radeon GPUs, and integrates with the FSR 4 plugin to help provide additional latency reduction when using FSR frame generation.
Unreal Engine 5.7
AMD is proud to collaborate with Epic Games to push the boundaries of real-time graphics. Unreal Engine 5.7 empowers you to build expansive, lifelike, and high-performance worlds filled with rich, beautifully detailed dense vegetation; author and render physically accurate layered and blended materials with true visual fidelity; and light complex worlds like never before.
You’ll also experience smoother and more intuitive animation and rigging workflows—and take MetaHuman further, all while getting instant guidance along the way from the new in-editor UE AI Assistant.
Combining AMD FSR 4 with Unreal Engine 5.7 means your projects deliver breathtaking visuals and optimized performance. Whether you’re crafting cinematic experiences or massive open worlds, ensure players enjoy uncompromised image quality and smooth gameplay.
