The Latest

The most recent AMD Radeon Adrenalin 26.6.2 WHQL drivers have revealed some hints about the upcoming evolutions of the FSR ecosystem. Some features are not yet available to users but have emerged through RadeonTuner, a utility that allows users to view settings present in the drivers but missing from the standard interface of the Adrenalin software.

As reported on the Chiphell forum, new options have been identified using a Radeon RX 9070 XT alongside the FSR 4.1.1 Override v2.3.0.2740 library. Within the FSR section, settings that have been absent so far appear, including:

• FSR Multi Frame Generation Override
• FSR Multi Frame Generation Ratio
• FSR Ray Regeneration Denoiser Override
• FSR Neural Radiance Caching Override

The most interesting element concerns FSR Multi Frame Generation, a technology that AMD has already hinted at in previous months through updates to the ADLX FidelityFX SDK package. The new entries show the possibility of selecting a frame generation ratio of up to 8x, a value higher than the current 6x implementation proposed by NVIDIA. Theoretically, this means the system could generate seven additional frames for each frame rendered natively.

Such a level of increment could translate into a very marked increase in frame rate, especially in the most graphically demanding games. At the same time, AMD will need to ensure precise control of frame pacing, latency, and image quality. It is highly likely that Anti-Lag technologies will also receive updates to adapt to such a high number of artificially generated frames.

Currently, AMD exclusively offers basic frame generation, namely one artificially generated frame for each rendered frame, while NVIDIA has introduced its Multi Frame Generation through progressive evolution, moving from 2x modes to the current 6x. NVIDIA has already hinted that the technology could go even further, while Intel proposes a solution up to 4x.

The updates found in the drivers do not only pertain to frame generation. The options dedicated to FSR Ray Regeneration and FSR Neural Radiance Caching suggest that AMD is considering allowing the manual activation of these technologies even in titles that do not officially support them. This type of approach is reminiscent of overrides already available for other Radeon driver features such as Fluid Motion Frames, Radeon Upscaling, and Anti-Lag, in addition to what has already been seen in the NVIDIA ecosystem.

Technologies like Neural Radiance Caching and Ray Regeneration are already expected in several games, including Call of Duty: Black Ops 7, Crimson Desert, Mafia: The Old Country, and Warhammer 40,000: Darktide. The potential introduction of overrides directly in the drivers could expand the pool of compatible titles and allow users to take advantage of these features beyond the list of official integrations.

AMD has never even announced some of these features, thus we have no availability date. However, the fact that they appear in the Adrenalin drivers indicates that development is progressing swiftly, and we may not have to wait long before we can put them to the test.
