At Gamescom 2025, AMD unveiled a major leap forward for game developers: the launch of FidelityFX SDK 2.0 and FidelityFX Super Resolution (FSR) 4.0.2. 
This marks a significant step toward the era of neural rendering, with AMD preparing its ecosystem for AI-driven graphics and the upcoming FSR Redstone update.
The new SDK is more than just an incremental patch – it’s a full re-architecture designed to support the next generation of Radeon hardware and machine learning graphics tools. While the existing FidelityFX SDK 1.1.4 remains available for continuity, version 2.0 introduces ML-ready features such as FSR 4 upscaling and FSR 3.1.5 analytical frame generation. Importantly, the platform allows AMD’s Adrenalin Edition drivers to automatically update ML-based technologies in games, sparing developers from pushing constant patches.
For players, this means smoother transitions: any title with FSR 3.1 support can be auto-upgraded to FSR 4 upscaling through future driver updates, while FSR 3.1.4 integrations will evolve into ML-based Frame Generation without developer intervention. Radeon RX 7000 users and older cards will still benefit from FSR 3.1.5, while the cutting-edge FSR 4.0.2 requires at least the upcoming Radeon RX 9000 Series.
FSR 4 itself brings notable improvements over its predecessor, including reduced ghosting on fast-moving objects, sharper preservation of particle effects, and far greater temporal stability. The transition path is also simplified thanks to its API consistency with FSR 3, plus official Unreal Engine 5 plugins (versions 5.1–5.6) that streamline developer adoption. AMD even provides pre-built, signed packages for developers seeking quicker integration.
The real highlight, however, is how FidelityFX SDK 2.0 sets the stage for FSR Redstone, AMD’s upcoming next-gen neural rendering technology aimed directly at competing with NVIDIA’s DLSS AI stack. If the early results with FSR 4 are any indication, the Red Team is closing the gap fast.

amd needs better marketing tho, ppl still think dlss only option
Unreal plugin support = more games will actually use it 🙌
