AMD’s latest “Redstone” FSR pack keeps the company behind on multi‑frame generation (MFG) compared to NVIDIA and Intel. A Reddit user uncovered that the new ADLX SDK adds IADLX3DFidelityFXFrameGenUpgradeRatioOption, letting developers pick the best MFG multiplier for performance and quality. This tweak signals AMD’s intent to close the gap. Users will see smoother gameplay in next‑gen titles as the feature rolls out.

Currently, FSR 4 tops at a 2× mode, while NVIDIA’s DLSS 4.5 offers 6× and Intel’s XeSS 3.0 delivers 4×, translating to higher frame rates. AMD’s method relies on a custom ML algorithm that blends per‑pixel motion with optical flow, producing a single interpolated frame between originals. The result is a moderate FPS lift—roughly a third of NVIDIA’s gain and half of Intel’s.

The new ADLX function, named IADLX3DFidelityFXFrameGenUpgradeRatioOption, aims to let users adjust the multiplier to match their hardware. By offering a scalable MFG option, AMD plans to introduce a 4× mode—or even a 6× mode—to match NVIDIA’s performance ceiling. This move could level the playing field for gamers who rely on software upscaling rather than costly hardware.

AMD’s upcoming FSR Diamond update, slated for the next‑generation Xbox, is expected to bundle neural rendering, ML‑based upscaling, dynamic MFG, and ray‑tracing enhancements. While concrete details remain sparse, the addition of MFG options signals AMD’s commitment to keeping its upscaling stack competitive. Ultimately, gamers will benefit from higher frame rates without needing premium GPUs.
