More evidence that Multi Frame Gen is on the way to AMD RDNA4 GPUs, potentially as high as 8x

If you're rockin' a current-gen AMD graphics card, there are yet more hints that multi frame gen (MFG), ie, frame gen that promises more than 2x frame rate, could soon be with us. 'Soon' is relative, of course, especially in the case of AMD, but detective work by a user on the Chinese forum Chiphell has revealed the presence of FSR MFG ratios up to 8x hidden in recent drivers (via Wccftech).

The user discovered the setting in the RadeonTuner tool, which hooks into the official AMD driver and provides a different app on top. This app, crucially, can present things in the driver that the regular AMD Adrenalin app might not yet give you access to. Things such as the FSR ratio drop-down.

To be clear, we already knew that MFG was probably being worked on by AMD, because earlier this year there was mention of "frame generation ratios" in documentation for the ADLX API. This implied that game developers were now being allowed to tinker with frame generation ratios, which implies the existence of ratios above 2x. In other words: multi frame gen.

Now, we have more confirmation of this, and not only that, but (A) it's seemingly in the actual drivers rather than just SDK documentation, and (B) the ratio maxes out at 8x. For reference, Nvidia's Multi Frame Gen maxes out at 6x.

As someone who uses an AMD RX 9070 XT as my daily driver, I am keenly aware of just how long it's taken AMD to implement promised technologies that Nvidia has already long been able to deliver. Technologies, that is, like multi frame gen, not to mention the latest upscaling and frame gen technologies in general, in more than a smattering of games.

The RadeonTuner tool also seems to show FSR Ray Regeneration and Neural Radiance Caching overrides, which will presumably allow us to override a game's settings to force FSR ray reconstruction and neural caching for better ray tracing.

I can't help but wonder, though, whether AMD users would rather more adoption of the latest FSR technologies we already have, such as regular 'Redstone' ML-powered frame gen and upscaling. There have been improvements on this front of late, though, with the technologies being allowed via driver-level overrides even for previous-gen AMD GPUs.

I also can't help but wonder how 8x frame gen will work in practice. I know for my part, I struggle to deal with the latency of even 3x or 4x frame gen on Nvidia cards. But I'm particularly sensitive to latency, so maybe 8x frame gen will have its place.
