AMD's FSR 3.1.4 Update: Laying the Groundwork for AI-Driven Redstone Technology

AMD Releases FSR 3.1.4 Update

AMD has released version 3.1.4 of its FidelityFX Super Resolution (FSR) technology, marking a significant step towards the integration of AI-driven rendering technologies. While the update appears minor on the surface, it sets the stage for AMD's ambitious Redstone project, slated for release in the latter half of 2025 1

Immediate Improvements in Image Quality

The FSR 3.1.4 update brings immediate enhancements to image quality, particularly addressing long-standing issues with temporal upscaling:

• Reduced ghosting on newly disoccluded pixels
• Improved clarity during fast camera movements
• Enhanced sharpness in dense environments 1

Preparing for Redstone and FSR 4

A key feature of the 3.1.4 update is the introduction of a signed, easily upgradable DLL as part of the "FSR 4 driver upgrade" system. This development significantly eases the process for developers to implement future updates, laying the groundwork for the integration of Redstone technologies 1

Redstone, first unveiled at Computex 2025, is set to form the backbone of FSR 4. It introduces four ML-powered features to AMD's rendering pipeline:

1. Neural Radiance Caching for accelerated global illumination
2. ML Ray Regeneration for rebuilding ray-traced detail
3. ML Super Resolution to replace the existing upscaler
4. ML Frame Generation for frame interpolation 1
