AMD FSR Redstone SDK & Unreal Engine Plugin Unveiled
Alongside the debut of its FSR Redstone update, AMD has rolled out new drivers designed for Radeon RX 9000 GPUs. These updates empower users to explore the latest machine learning-based suite. Developers can now access the FSR Redstone SDK to seamlessly incorporate these advancements into their games. Furthermore, AMD has outlined future directions for its FSR suite, supported by three pivotal research papers that pave the way for the next wave of graphics technologies.

Official Note: The AMD FSR SDK is our easy-to-integrate solution for developers looking to include FSR features in their games without any of the hassle of complicated porting procedures.
This initial release of the Redstone neural rendering technology heralds the public release of:
- AMD FSR Upscaling 4.0.3
- AMD FSR Frame Generation 4.0
- AMD FSR Ray Regeneration 1.0
- AMD FSR Radiance Caching (Preview)
What’s New in AMD’s FSR SDK 2.1?
Building on the foundations laid by FidelityFX SDK 2.0, the FSR SDK 2.1 introduces several enhancements. Future releases of AMD Software: Adrenalin Edition drivers will automatically update the ML-based technologies used in games, ensuring players benefit from the latest advancements without needing specific game updates. Games previously equipped with AMD FidelityFX Super Resolution 3.1 and later will see automatic upgrades to AMD FSR Upscaling 4.0.3, while those with AMD FidelityFX Frame Generation 3.1.4 will transition to AMD FSR Frame Generation 4.0.
An updated Unreal Engine plugin is also available, enhancing developer capabilities further.
Innovations in AMD FSR Technologies
AMD FSR Upscaling introduces a revolutionary upscaler that markedly enhances image quality. This ML-powered technology reconstructs visuals from lower-resolution frames, rivaling or surpassing native rendering quality, and utilizing AMD RDNA 4 architecture’s ML acceleration.
AMD FSR Frame Generation employs advanced ML algorithms to craft high-quality intermediate frames, minimizing common artifacts and boosting frame rates for smoother gameplay when used with FSR Upscaling and Radeon Anti-Lag 2.
AMD FSR Ray Regeneration offers a real-time denoising solution, turning ray-traced data into clean visuals, especially when used alongside other Redstone technologies.
AMD FSR Radiance Caching leverages machine learning to enhance illumination caching, promising dynamic lighting environments with reduced computational demand.
