Open-Source Hack Brings DLSS Frame Gen to RTX 30-Series GPUs

An open-source mod brings Nvidia’s DLSS Frame Generation to older RTX 30-series cards — and the latest update cuts generation latency by up to 35%.

Developer sdli1995 released version 0.2.4 of dlssg_for_sm86 on GitHub. The tool uses a custom C++ wrapper to run DLSS frame generation on RTX 30-series (and RTX 20-series) cards in DirectX 12 games. The 0.2.4 update fixes long-term VRAM leaks, repairs history frame glitches, and trims GPU frame generation overhead by 25% to 35% across 1080p, 1440p, and 4K tests on an RTX 3080 Ti.

Why it matters: Nvidia officially locked DLSS Frame Generation to RTX 40-series hardware. This project proves older Ampere GPUs can handle generated frames in games like Black Myth: Wukong, offering a performance boost without forcing a full graphics card upgrade.

Know this: Installation requires copying version.dll and dlssg_sm86.ini into your game’s main executable directory without needing Python or the CUDA Toolkit. Generated frames consume roughly 320 MiB to 770 MiB of additional VRAM depending on resolution, and because the project uses system DLL proxying, some antivirus scanners may raise false alarms.

Your RTX 3080 Ti isn't ready for retirement just yet.
