AMD FSR Redstone: Image Quality Frame Gen Comparison, Latency Benchmarks, Ray Regeneration

AMD FSR Redstone: A Comprehensive Overview

This video provides a detailed look at AMD's FSR "Redstone"—a rebranded and expanded suite of features for FidelityFX Super Resolution. The update introduces a new machine-learned frame generation model, ray regeneration, and outlines future plans for radiance caching. This summary aims to distill the key findings from the review.

What is AMD Redstone?

Redstone bundles both new and existing FSR technologies. The headline additions—a machine-learned frame generation model and ray regeneration—are available now. Radiance caching is slated for a future release. It's important to note that these new technologies are officially supported only on the latest RX 9000 series GPUs.

Deep Dive: Key Features & Performance

FSR Radiance Caching

This upcoming feature is designed to optimize ray-traced illumination. By using a pre-trained machine learning model, it aims to achieve high-quality ray tracing visuals with significantly fewer computational demands. While available to developers, it is not yet implemented in any consumer games.

Image Quality: Cyberpunk 2077

A blind test compared the new Redstone Frame Generation against stock footage (without any frame gen). The Redstone version demonstrated clear improvements over the previous FSR 3.1 Frame Generation, particularly in reducing visual artifacts like ghosting and flickering. However, some issues, such as image doubling, were still observed.

Image Quality: Marvel Rivals

The visual differences between Redstone and FSR 3.1 were more nuanced in this title. Redstone generally provided a more stable image with reduced jitter in shadows and particle effects.

Latency Benchmarks

Without FPS Cap: In both Marvel Rivals and Cyberpunk 2077, enabling frame generation increased system latency. The latency performance between Redstone and FSR 3.1 was similar.

With FPS Cap (Cyberpunk 2077): When an FPS cap was applied, frame generation notably worsened latency and made it less consistent, highlighting a potential trade-off for smoother frame rates.

Ray Regeneration in Call of Duty: Black Ops 7

This technology was tested in the game's multiplayer. Ray regeneration improved the clarity and sharpness of reflections and water surfaces, making them appear less muddy and higher resolution. Broader analysis is limited due to minimal current game support for the feature.
