For AMD Radeon and more: FSR 3.1.4 as a harbinger of FSR Redstone

AMD has officially put another piece of its own upscaling puzzle on the table with FSR 3.1.4, report our colleagues at Computerbase. At first glance, it looks like a routine update: a little less ghosting here, an optimized SDK there. But there is a clear plan behind these technical cosmetics and it’s called FSR Redstone. If you just stare at version numbers, you might think it’s an isolated upgrade. In fact, 3.1.4 is the gateway to the next generation of the FidelityFX suite – and it will offer much more than just “sharper pixels”.

The lever in the driver, how AMD upgrades games retrospectively

With FSR 3.1, AMD has already proven that its own drivers are more than just software managers. A small switch, a whitelisting by AMD and suddenly a game can display FSR 4 without the developer having to change a single line of code.
With FSR 3.1.4, AMD is apparently planning the same coup in the direction of Redstone. So if you integrate FSR 3.1.4 today, you could soon have access to the Redstone functions with a simple driver update. That sounds convenient, but it is also a powerful control instrument for AMD: you control which games can enjoy the high-end features and when.

More than just Super Resolution?

FSR Redstone will not simply be “FSR 4 plus marketing glitter”. The suite includes:

• Improved FSR 4 Super Resolution
• AI-based frame generation (possibly multi frame)
• AI Ray Reconstruction for more realistic ray tracing
• Neural Radiance Caching, i.e. AI-based, accelerated global illumination for path tracing

While frame generation can probably be easily retrofitted via a driver, it is questionable whether ray reconstruction and radiance caching can also be activated automatically. Both features have a deep impact on the rendering pipeline – and not every game will be prepared for this.

The SDK monopoly – why FSR 4 is still in the vault

Developers can already install FSR 3.1.4 and its SDK, and AMD even provides a fresh plug-in for Unreal Engine 5.6 (including Anti-Lag 2 support). Ironically, there is still no official SDK for FSR 4, a clear indication that AMD wants to stage Redstone as a complete package instead of releasing FSR 4 in isolation in advance. There are two sides to this: On the one hand, developers can optimize early, on the other hand, they remain dependent on AMD’s release schedule.

Strategic importance

AMD is taking a two-pronged approach with FSR Redstone:

1. Technological parity with Nvidia – frame generation, AI ray tracing and lighting optimizations are clearly targeted at DLSS 3.5.
2. Market penetration via openness, FSR remains hardware agnostic and runs on Radeon, GeForce and Intel Arc. This is not only customer-friendly, but also indirectly forces Nvidia to make its own technologies more open.

However, AMD’s control over driver release is a double-edged sword: it allows fast updates and quality assurance, but also gives the manufacturer the power to selectively release features – politically, marketing-wise or simply according to its own priorities.

Outlook

AMD does not give an exact release date for Redstone, only that it will be released in 2025. However, anyone integrating FSR 3.1.4 today is already building the runway.
It will be exciting to see whether Redstone actually works in all games or whether, as is so often the case, it comes down to a combination of “release policy” and “technical feasibility”.
