The latest version of AMD's ADLX developer kit has been published a scant five days ago, and some eagle-eyed folks have already spotted a meaningful new addition that's relevant for AMD gamers worldwide. This revision adds support for an incoming driver-level override for FSR4 Frame Generation (FG), with a twofold purpose.
First, it lets games coded with FSR3.1 FG support to upgrade their frame generation to the high-quality AI-based method FSR4 uses. Second, it'll at some point enable selecting the frame generation ratio, a value that currently sits at only 2x for FSR4 but ought to almost certainly include 4x and 6x in the near future. This new toggle ought to be quite similar the existing Adrenalin toggle to upgrade the upscaling type to the latest version.
All told, this should be welcome news for most any gamer with and AMD graphics card. The greatest benefiters, though, will undoubtedly be those with modest cards, who'll enjoy added smoothness and improved perceived visual quality. Plus, getting a free upgrade for games using FSR 3.1 FG is the cherry on top.

Adding fuel to the fire, FSR FG has historically had issues with frame pacing, so adding higher ratios and smoothing out frame delivery are sorely needed additions to bring AMD to feature parity with its main competitors.
The new feature's technical name is "IADLX3DFidelityFXFrameGenUpgrade", and it's a driver-level interface that includes "GetRatio" and "SetRatio" functions among others. Those, in turn, use the ratio values defined by "ADLX_FFX_FRAME_GEN_RATIO". That sounds like a lot of technical gobbledygook, but the relevant bit is that it exposes driver-level functionality for both upgrading the FG type, and setting the ratio.
As shown in the relevant SDK lines , the possible ratios are "unknown" and "2x". Obviously, 2x is the currently available ratio, but it's a safe enough bet to that AMD wouldn't bother adding the Set/GetRatio functions if it wasn't planning on having values beyond that at some point. There's little telling when this will happen precisely, but we're guessing sometime soon, as the presence of this SDK functionality implies there's an extant necessity for it.
