DLSS Multi Frame Generation mod hits RTX 40-series GPUs — tested and working

A new community mod ports DLSS Multi Frame Generation — NVIDIA's RTX 50-series exclusive frame interpolation feature — to RTX 40-series GPUs. Tom's Hardware ran tests and confirmed it works.

Multi Frame Generation is the DLSS 4 upgrade that generates multiple frames between each rendered frame, multiplying FPS output beyond the single-frame injection DLSS 3 offered on 40-series cards. NVIDIA locked it to Blackwell hardware. The mod bypasses that restriction. Tom's tested it across several titles and saw frame rate multipliers similar to what 50-series cards get, though stability wasn't flawless — some games showed artifacting or stutters, especially in fast camera pans.

This is a good proof-of-concept for anyone sitting on a 4080 or 4090 who wants a preview of DLSS 4's interpolation muscle without upgrading. It's not official, so expect rough edges and no support if something breaks. The mod's longevity depends on whether NVIDIA cracks down with driver updates or leaves it alone.

If you're already running a 40-series card and want to squeeze more frames out of demanding games, check your current optimization settings before modding — clean configs often unlock 10-20% without the risk of unofficial patches.
