AMD has launched FSR Redstone, a suite of graphics and performance-enhancing technologies for Radeon PC gamers, which includes over 200 games supporting the machine-learning upscaling tech, FSR4. The update also introduces ML-based frame generation for over 30 titles. However, FSR Redstone primarily absorbs FSR4, and users need a Radeon RX 9000-series card to access these features. Adoption of the new hardware remains slow, with less than 0.15% of PC gamers currently using it.

2025-12-10 | Ars Technica: AMD’s next-gen “FSR Redstone” brings big gains, as long as you’re using a new GPU

AMD's upcoming "FSR Redstone" aims to enhance image quality and performance through new ray-tracing and frame-generation features, but it will only be compatible with AMD's latest RDNA4 GPUs, such as the Radeon RX 9070 and RX 9060 series. FSR Redstone includes four technologies, with FSR Radiance Caching being a key feature that uses a neural network to optimize indirect lighting and global illumination by predicting light bounces, reducing GPU workload.

AMD has launched FSR Redstone, an overhaul of its upscaling and frame generation software, which includes machine learning-based frame generation, Ray Regeneration, and Radiance Caching features. These enhancements improve image quality and performance, bringing AMD closer to Nvidia's DLSS technologies. FSR Redstone is available for developers and gamers with AMD's RNDA 4 GPUs. Key features include improved ray-traced reflections and reduced computational load for lighting effects, with full support expected in 2026.

2025-12-10 | Rock Paper Shotgun: AMD's FSR Redstone upgrades are a match for DLSS, even if they slay a sacred cow to do it

AMD has launched FSR Redstone, a suite of upgrades for upscaling, frame generation, and ray tracing, designed to compete with Nvidia's DLSS 4. Unlike previous versions, Redstone requires the latest RX 9000 series GPUs, focusing on sophisticated machine-learning tools. The new FSR Upscaling shows improved image quality, while FSR Frame Generation offers cleaner, more consistent fake frames, albeit with some input lag. Ray Regeneration enhances ray tracing effects, and Radiance Caching is expected in 2026. Overall, Redstone marks a significant advancement for AMD's technology.
