AMD GPUOpen update hints at adjustable FSR Frame Generation ratios
AMD may be getting closer to ratio-based frame generation, at least based on a new change spotted in GPUOpen documentation. The latest ADLX 1.5 materials add a new “ FidelityFX Frame Generation Upgrade ” interface with methods for checking support, enabling the feature, reading the current ratio, listing available ratios, and setting a ratio. AMD does not call this Multi Frame Generation anywhere in the docs, but the addition of ratio controls suggests the company is preparing something beyond a single fixed frame generation mode.

AMD’s newly released ADLX 1.5 documentation, published on April 17, adds a Frame Generation Upgrade interface with ratio query and set functions, hinting that broader multi-frame generation controls may be close.

GPUOpen already says future Adrenalin releases can automatically upgrade games that integrated FSR 3.1.4 to ML-powered FSR Frame Generation 4 in DirectX 12 titles. AMD also says FSR Frame Generation 4 is the ML-based version designed for RDNA 4, while an analytical fallback remains for older hardware. At this point it’s not clear if said ‘ratio’ based frame generation would rely on an ML algorithm or not.

It is still unclear which platforms will support these ratios, whether the feature is limited to RDNA 4 and Radeon RX 9000 series GPUs, or whether older cards could receive an analytical version with similar controls. Tools such as DLSS Enabler and Lossless Scaling have already shown that AMD hardware can run this kind of technology, although performance, latency, and image quality still depend heavily on the base frame rate and the GPU itself. AMD’s own implementation could deliver better results, but it is also possible that this change does not point to full multi-frame generation support after all. Either way, AMD needs to explain what comes next, because Radeon users are still waiting for a clearer software direction.
NVIDIA DLSS Dynamic MFG and Intel XeSS MFG is already here
Meanwhile, NVIDIA and Intel users do have their versions with frame gen up to 6 frames. Hardware support is limited to certain architectures, though, so far Intel’s version seems to support more hardware than NVIDIA’s.
