How to get unlocked Multi Frame Gen working on an RTX 40-series graphics card
Nvidia’s Multi Frame Generation (MFG), an AI-powered frame interpolation technology that can create up to five frames for every rendered frame, has been officially restricted to RTX 50-series graphics cards. However, users with older RTX 40-series GPUs can still access the feature through unofficial workarounds and software modifications.
Originally introduced in 2022 as 2x Frame Generation exclusively on RTX 40-series cards, the expanded MFG version promises significant improvements in frame rate smoothing and gaming smoothness by leveraging AI to generate intermediate frames. Nvidia’s decision to limit the newest MFG implementation to its latest RTX 50-series lineup is widely interpreted as a hardware segmentation strategy to incentivize upgrades.
The barrier to entry for RTX 50-series cards remains substantial, with flagship models like the RTX 5090 facing availability issues at recommended retail prices. This has motivated PC gamers to explore alternative methods to enable MFG on existing RTX 40-series hardware.
While specific technical details on enabling MFG on older cards are not fully provided in the excerpt, the article indicates that software tinkering can unlock most of MFG’s performance benefits on RTX 40-series GPUs.
