PS5 Pro and AMD Redstone AI: Major Upgrade to FSR and Frame Generation

A big update is coming about how PlayStation 5 hardware is improving and how AMD is increasingly using AI-powered upscaling. As new information, live demonstrations, and reports of early tests come out, it becomes much clearer how much FSR implementations, frame generation, and PSSR integrations have improved.

Developers and users are beginning to see meaningful visual upgrades, cleaner animations, and smarter frame reconstruction, driven by AMD's new machine learning models.

We are now seeing AMD specifically working with PS5 Pro, confirmed through updates and documentation. Technologies like FSR act as upscalers that leverage AI to improve visuals, similar to how Nvidia uses DLSS. Because AMD produces the GPUs for PS5 and PS5 Pro, they can leverage both their hardware and software to significantly enhance visual quality through AI-driven frame generation.

New FSR Redstone, exclusive to RDNA 4 MP PC hardware and only on PS5 Pro console, is a major shift forward.

High-level analytical versions of super resolution and frame generation will be supported on RDNA and RDNA 3.5 hardware. However, AMD will not support older cards with frequent updates, such as the AI-powered MLFSR technology.

The pre-alpha Optiscaler build demo shows huge improvements over the legacy FSR frame generation. We are finally seeing live usage and implementation in real game environments. The Optiscaler pre-alpha demo demonstrates improved visual stability, reduced noise, and cleaner reconstruction compared to older models.

A Reddit user demonstrated AMD's new ML-powered FSR Redstone frame generation running in Monster Hunter Wilds, even though the game was never designed to support it. A user compared an older version of FSR Redstone to the newer ML frame generation model after the community Optiscaler pre-alpha build went around official inclusion limits.

The results show that the arms look cleaner, the bird moves look smoother, the particle rendering looks better, and the shadows and sand effects are less blotchy.

AMD began rolling out Redstone ML frame generation more broadly earlier this week through the Adrenaline 25.12.1 update. It is positioned as a more advanced replacement for FidelityFX Super Resolution 3. Redstone requires newer FSR integrations and newer Radeon hardware, as updated camera parameter support is required to enable ML frame generation.

We see major upgrades, including reduced ghosting, fewer reconstruction artifacts, and improved frame prediction. Redstone uses an ML model to predict intermediate frames from motion vectors and depth data, rather than relying on heuristic interpolations like older FSR frame generation.

When comparing the old FSR to the new Redstone ML version, the differences are noticeable. On older builds, there aren't enough frames to render shadows and particle effects smoothly; as a result, they appear grainy or blotchy. Jitter, inconsistency, or visual noise can be seen in the figure's hand movements and in the textures of the birds, rocks, and sand.

With Redstone's machine learning integration, this looks a lot better.

It makes the movement smoother, the particle effects more stable, and the frame rebuilding more accurate.

We can look at character animations, such as swinging a weapon with elemental effects, to understand the improvements. AI-generated frames fill in the blanks more accurately because they learn patterns from repeated animations. Redstone makes these interpolated frames noticeably cleaner and more consistent.

The Optiscaler tool intercepts a game's frame generation calls and reroutes them to alternative backends, including new FSR passes. This allows ML frame generation to be exposed even in games with older AMD FSR implementations.

Because this is unsupported third-party software running outside AMD's intended deployment path, it carries risks, including anti-cheat detection, and users should be cautious. However, it demonstrates that the technology is functional across multiple games and can meaningfully elevate visual quality.

There is now clear evidence that the AI technology in PS5 Pro is a huge success. Redstone's Cleaner Reconstruction, Reduced Artifacts, and Better Frame Generation show that the console can deliver much better performance and visual quality. The new changes make it clear how AMD's AI models improve gameplay, particle effects, and graphics quality.

The technology is now available, and we can expect future games and updates to make use of these changes. PS5 Pro will get the most out of this, and as more devs start using the updated FSR and Redstone features, excitement is growing.
