AMD’s FSR “Redstone” is Here: A New Toolkit for Next-Gen Game Graphics
If you’ve been waiting for games to look better and run smoother, AMD just dropped a massive upgrade for developers that will eventually land in your favorite titles. They’ve officially released their FSR “Redstone” Software Development Kit (SDK) and a new Unreal Engine plugin, making it easier than ever for game studios to integrate AMD’s latest machine-learning graphics magic.
This isn’t just a minor update. “Redstone” introduces a suite of brand-new technologies designed to push visual fidelity and performance further, especially for owners of the latest Radeon RX 9000 series graphics cards. Let’s break down what’s in the toolbox and why it matters for the future of gaming.
The Redstone Toolkit: Four Key Upgrades for Game Devs
The new SDK packages several powerful technologies together. Here’s what each one does:
- AMD FSR Upscaling 4.0.3: This is the heart of the performance boost. It’s a machine learning-powered upscaler that reconstructs a sharp, high-resolution image from a lower-resolution frame. The result? You get performance close to playing at the lower resolution, but with image quality that aims to match or even beat native rendering. The latest version promises reduced ghosting, better particle effects, and more stable image quality over time.
- AMD FSR Frame Generation 4.0: This tech is all about super-smooth gameplay. It uses advanced AI to generate entirely new frames between existing ones, effectively doubling your frame rate for ultra-fluid motion. The new ML-based approach aims to reduce common artifacts like ghosting, making the generated frames look more natural.
- AMD FSR Ray Regeneration 1.0: Ray tracing looks incredible but is notoriously demanding and can produce visual “noise.” Ray Regeneration is a dedicated AI denoiser that cleans up that noise in real-time, resulting in clearer, more precise ray-traced reflections, shadows, and lighting without a massive performance toll.
- AMD FSR Radiance Caching (Preview): This one is a glimpse into the future of game lighting. It’s an AI model that works with complex path tracing to simulate how light bounces around a scene in real-time. This allows for incredibly rich, dynamic, and realistic global illumination—the kind that makes environments feel truly alive—without developers having to “pre-bake” the lighting.
A Smarter System: Future Updates Without Game Patches
One of the most player-friendly features of this new SDK is a shift in how updates are delivered. With FSR Redstone, future improvements to these ML-based technologies can be delivered directly through AMD’s Adrenalin software drivers.

What does this mean for you? If a game has already integrated FSR 3.1 or later, it could automatically receive upgrades to the newer “Redstone” versions of upscaling and frame generation. You won’t always have to wait for the game developer to issue a specific patch to get the latest image quality and performance enhancements from AMD.
Hardware Requirements: The RX 9000 Series Takes the Lead
To experience the full, ML-accelerated power of the new FSR Redstone features—especially Frame Generation and Ray Regeneration—you will need one of AMD’s newest Radeon RX 9000 series graphics cards (based on the RDNA 4 architecture).
The good news is that AMD has built in backward compatibility. Older GPUs that support Shader Model 6.2 or above will still be able to use analytical (non-ML) versions of the upscaling and frame generation tech, which is based on the previous FSR 3.1 standard. This ensures a wide range of players can benefit, even if the latest AI features remain exclusive to the newest hardware.
What’s Next for FSR? AMD Hints at the Road Ahead
AMD isn’t stopping with Redstone. In their announcement, they pointed to three key research papers that will guide the next phase of FSR development. While technical, these papers signal AMD’s ongoing investment in areas like:
- Further advanced neural rendering techniques.
- Pushing the boundaries of real-time denoising and reconstruction.
- Enhancing global illumination methods for even more realistic lighting.
This tells us that “Redstone” is a major step, but not the final destination, for AMD’s upscaling and graphics enhancement roadmap.
FAQs About AMD FSR Redstone
Q: I have an older AMD graphics card (like an RX 6000 or 7000 series). Do I get anything from this?
A: Yes, but with an asterisk. The full, AI-powered features of FSR Redstone require an RX 9000 series card. However, the SDK includes backward-compatible modes. Games using the new SDK can offer you the analytical versions of upscaling and frame generation (based on FSR 3.1), so you’ll still see performance benefits, just not the latest ML-enhanced versions.
Q: When will I see these features in my games?
A: The SDK and Unreal Engine plugin are available for developers now. It will take time for studios to integrate these tools into their current and upcoming projects. The first games to showcase “Redstone” will likely be titles still in development or those receiving major graphical updates.
Q: Does this only work with Unreal Engine?
A: While a dedicated Unreal Engine plugin makes integration easier for devs using that engine, the core FSR Redstone SDK is designed to work with multiple graphics APIs (like DirectX 12 and Vulkan) and can be integrated into other game engines.
Q: Is FSR Ray Regeneration the same as ray tracing?
A: No, it’s a companion technology. Ray tracing calculates how light travels. That process inherently creates visual noise. Ray Regeneration’s job is to use AI to clean up that noise after the ray tracing is done, resulting in a much cleaner final image.
Q: As a player, do I need to do anything to enable this?
A: For the most part, no. Once a game supports these features, they will typically be options you can toggle in the game’s graphics or display settings menu, just like current upscaling options. The potential driver-based updates for existing games would happen automatically through AMD Adrenalin Edition.
