While companies like Nvidia and Intel push ahead with multi frame generation technology in its latest version of DLSS and XeSS, respectively, AMD’s FSR still only offers 2x FG (you may call this single frame generation as only one additional AI-generated frame is rendered – the other one is natively rendered).

Most recently, Nvidia fully rolled out DLSS 4.5 with support for Dynamic Frame Generation and up to 6x Frame Gen. The former is a feature that allows DLSS to proactively change the amount AI-generated frames being pumped into your game, while maintaining a target FPS. In other words, it can help make up for low frame rates in more demanding areas and at the same time stop frame generation from being overkill, especially since a higher multiplier will mean higher latency.

FSR Frame Generation upgrade on the way?

Due to the fact that AMD’s ADLX developer kit is open-source and freely available to inspect on GitHub, anyone with the knowhow can scan through the latest changes and spot anything meaningful. SDK version 1.5 was released last week and reveal some interesting references to a driver-level override for FSR 4 Frame Generation, now simply known as AMD FSR Frame Generation following the transition to the new FSR Redstone branding.

Expected to arrive as a driver-level override (similar to DLSS Override in the Nvidia App), the latest update firstly allows FSR 3.1 Frame Generation supported games to run the new FSR 4 (FSR FG) standard, which uses an improved ML-based approach. Secondly, AMD may have plans to increase the ratio, or multiplier, which may enable 4x or 6x FG in the near future.

The code in question currently refers to “unknown” and “2x” ratios, and it is speculated that AMD will soon unlock higher multipliers due to the functionality being in place.

On a technical level, the code refers to a feature named “IADLX3DFidelityFXFrameGenUpgrade” that acts as a driver-level interface with “GetRadio and “SetRatio” functions. These functions use the ratio values pictured above, defined by “ADLX_FFX_FRAME_GEN_RATIO” – in other words, it lays the foundation for upgrading the Frame Generation type and its ratio or multiplier.

A frame generation upgrade would be welcomed by Radeon GPU owners, especially since it doesn’t look like rival Nvidia intends to slow down. Official support for FSR 4/Redstone on RX 7000 series is still lacking, however, and it has long been one of the biggest ask from fans. But at least there’s the potential for more powerful frame gen in the meantime.
