Modders have built a software patch called DLSSG SM86 that brings NVIDIA's advanced frame generation technology to older GeForce RTX 30 Series graphics cards. This development matters because it gives owners of legacy hardware access to features previously locked behind newer, more expensive chips. Gamers can now generate extra frames in supported titles without upgrading their entire system.
New proxy software enables DLSS 4 frame generation on legacy hardware
The project targets the GeForce RTX 3080 and RTX 3080 Ti specifically. It enables DLSS Multi Frame Generation in both 2X and 4X modes. The 4X mode leverages AI to generate three additional frames for every rendered frame. This approach significantly boosts visual smoothness in demanding games like Cyberpunk 2077.
- Mod Name: DLSSG SM86
- Supported Hardware: GeForce RTX 30 Series (RTX 3080, RTX 3080 Ti)
- Technology: DLSS Multi Frame Generation (2X and 4X modes)
- Implementation Method: SM86-compatible backend/proxy redirecting calls to DLSSG 310.1
- Game Example: Cyberpunk 2077
SM86 serves as the internal CUDA architecture code for the RTX 30 Series. The mod works by creating a compatible backend proxy that runs alongside the game. This proxy redirects technical calls to the DLSSG 310.1 implementation, which is the DLSS 4 Frame Generation runtime library. The solution preserves original game files and avoids messing with the rendering pipeline.
Previous community mods often replaced NVIDIA's DLSS with AMD's FSR to achieve frame generation. Those earlier attempts suffered from frame-pacing inconsistencies and lower image fidelity. This new mod avoids those pitfalls by using NVIDIA's native runtime directly. It maintains the visual quality associated with official DLSS implementations.
We touched on NVIDIA DLSS Multi Frame Generation Mod in our earlier Nvidia coverage. The current project extends that technology to the RTX 30 Series generation. Official support for Multi Frame Generation remains exclusive to the GeForce RTX 50 Series for now. Modders continue to bridge the gap between generations through software innovation.
The mod allows RTX 30 Series users to access DLSS 4 Frame Generation capabilities. It functions as a proxy that redirects calls to the newer runtime library. Users should note that performance and latency characteristics may differ from official RTX 50 Series hardware. The patch offers a viable path for extending the life of existing GPUs.
