AMD, with its latest FSR "Redstone" graphics technology pack, is currently the only major GPU maker without multi-frame generation (MFG) in its suite of advanced graphics technologies. However, this might be changing soon as AMD is pushing new updates to its FSR SDK, as discovered by a Redditor. In the AMD Device Library eXtra (ADLX) SDK update, AMD is implementing a new function called IADLX3DFidelityFXFrameGenUpgradeRatioOption. While this lengthy name might not mean much at first glance, the ADLX SDK describes it as a feature that will allow users to choose the most optimal frame generation multiplier for performance and visual quality, essentially matching what multi-frame generation means in modern stacks like DLSS from NVIDIA and XeSS from Intel. For instance, AMD currently supports frame generation with up to a 2x mode with its FSR 4 technology, but it lags behind the modern 6x mode that NVIDIA offers in its DLSS 4.5 pack and the 4x mode that Intel provides in XeSS 3.0, which can significantly boost FPS. AMD's current solution uses a custom ML-based algorithm to generate intermediate frames using optical flow estimation and motion vectors. FSR 4 uses per-pixel motion and appearance, combined with motion vectors, to generate a new frame between two frames, resulting in a high-quality frame. This leads to a significant FPS increase, but it is only a third of what NVIDIA can achieve and half of what Intel offers. Therefore, AMD is scaling this technology for a new FSR release, and we might see a 4x mode or even a 6x mode to match NVIDIA.
