AMD appears to be planting driver hooks for a broader version of FidelityFX Super Resolution, including a multi-frame generation setting that lists ratios as high as 8x. The catch, and it is a large one, is that the controls seen so far do not work.
A screenshot posted to the Chiphell forums shows AMD's Adrenalin Edition 26.6.2 driver exposing hidden experimental options inside RadeonTuner, a third-party open-source alternative to AMD's own Adrenalin Software. The listed controls include a new multi-frame generation ratio, plus override switches for an FSR ray regeneration denoiser and FSR neural radiance caching.
The menu labels suggest AMD is testing frame generation beyond the single extra-frame approach associated with earlier versions of the technology. The visible ratio options reportedly run from 1x to 8x. If an 8x mode behaved as the label implies, a game rendering at 60 frames per second could be presented at up to 480 frames per second. That would be roughly double the current ceiling Nvidia offers on its RTX 50-series GPUs, according to the report.
That math is theoretical. The settings are inactive, and AMD has not confirmed that it will ship an 8x mode, ship these controls to existing Radeon GPUs, or use the same names in a public release.
Placeholders, not a product announcement
The RadeonTuner developer addressed the finding in a GitHub discussion, saying AMD sometimes adds the names of future driver settings months before the underlying feature is implemented. The developer described the newly visible multi-frame generation ratios, including the 8x option, as placeholders added for testing.
That means the labels may describe AMD's internal experiments rather than the final feature set. Driver strings often leak intent, but they do not guarantee timing, GPU support, image quality, latency behavior, or whether a switch will survive to release. A menu entry is cheap. Making generated frames look good under motion, input latency, and game-engine weirdness is the hard part.
The other experimental labels point in the same direction. Ray regeneration generally refers to machine learning-assisted reconstruction or denoising for ray-traced effects, while neural radiance caching is a rendering technique that can use learned approximations for lighting. The screenshot does not show those systems running, only override options carrying those names.
FSR Diamond is the nearby context
Microsoft has said its upcoming Xbox platform, codenamed Project Helix, will include FSR Diamond, formerly called FSR Next. Microsoft described it as an AI-powered rendering suite with machine learning upscaling, ray regeneration, and multi-frame generation. AMD graphics chief Jack Huynh later called FSR Diamond the result of a multi-year engineering collaboration with Microsoft.
No public evidence ties the hidden Adrenalin 26.6.2 settings directly to FSR Diamond. The overlap in feature names is still hard to ignore: multi-frame generation, ray regeneration, and neural rendering-related controls are showing up in the Radeon driver stack while AMD and Microsoft are talking about the next generation of FSR.
For Radeon owners, the practical answer is boring but useful: nothing new can be enabled yet. The driver appears to contain scaffolding for experiments AMD has not announced as shipping features.
