Today, December 10, AMD officially unveiled FSR Redstone, a new suite of graphics technologies designed to dramatically improve game visuals and boost performance with minimal quality loss.<\/p>\n

The Redstone stack includes four separate tools, each targeting a different part of the rendering pipeline. One of the biggest upgrades is FSR Frame Generation, which uses a specially trained neural network to predict and insert high-quality generated frames. AMD says this not only smooths gameplay but also fixes shadow artifacts previously seen in FSR 3.1\u2014though issues with text rendering were not addressed.<\/p>\n

\"The
The third FSR Redstone tool is FSR Ray Regeneration, an AI-powered technology that uses neural networks to reconstruct ray-traced data in real time.<\/figcaption><\/figure>\n

Another major addition is FSR Radiance Caching, a global illumination technique that precalculates heavy indirect lighting at select points in a scene. This data is then interpolated for nearby pixels, reducing the number of rays and reflections needed for ray tracing. The result is faster processing of indirect lighting, soft reflections, and color blending, provided the lighting conditions don\u2019t change dramatically between cached points.<\/p>\n

\"Meanwhile,
Meanwhile, FSR Upscaling, which is part of FSR Redstone, hasn\u2019t received an update, according to AMD\u2019s slides.<\/figcaption><\/figure>\n

The third component, FSR Ray Regeneration, uses AI to reconstruct ray-traced data in real time. This improves the detail of reflections, lighting, and water effects while lowering GPU workload\u2014essentially AMD\u2019s answer to NVIDIA\u2019s Ray Reconstruction.<\/p>\n

FSR Upscaling, the fourth tool, remains unchanged. AMD confirmed it was previously known as FSR 4 and noted that game support has quadrupled since launch. According to AMD, the full Redstone toolkit can deliver 2.8\u00d7 to 4.7\u00d7 higher performance in supported titles.<\/p>\n

\"The
The only problem is that the new features work exclusively on RDNA 4 generation video cards, meaning even relatively new models won\u2019t get them.<\/figcaption><\/figure>\n

However, there\u2019s a catch:
FSR Redstone is exclusive to RDNA 4 GPUs, meaning even relatively recent AMD graphics cards will not support the new features.<\/p>\n","protected":false},"excerpt":{"rendered":"
