Witcher 3 RTX 40 MFG Bridge — Enable Multi Frame Generation via DLSS Enabler
A compatibility bridge for The Witcher 3 Next‑Gen DX12 that lets DLSS Enabler drive NVIDIA Multi Frame Generation on RTX 40-series GPUs, enabling up to x3 frame generation in testing.
- Allows DLSS Enabler to drive NVIDIA Multi Frame Generation (MFG) on RTX 40-series GPUs
- Runs Streamline 2.11.1 alongside the game's Streamline 1.5.6 while preserving the game's interface
- Enables up to x3 frame generation on tested RTX 4070 hardware (approx. 40→100 FPS example)
- Includes installer and uninstall scripts for bin\x64_dx12 integration
Requirements: Requires The Witcher 3 Next‑Gen DX12 executable, an NVIDIA RTX 40‑series GPU, a recent NVIDIA driver (R570 or newer recommended), DLSS 310‑series DLLs (nvngx_dlss.dll and nvngx_dlssg.dll) in bin\x64_dx12, and DLSS Enabler 4.8.x installed separately into bin\x64_dx12 using the dxgi.dll loading method (DLSS Enabler is not included).
This compatibility bridge enables Multi Frame Generation (MFG) for The Witcher 3 Next‑Gen DX12 by allowing DLSS Enabler to drive frame generation on NVIDIA RTX 40-series GPUs. The game ships with NVIDIA Streamline 1.5.6, which does not expose MFG to external tools; the bridge runs a Streamline 2.11.1 runtime alongside the game while preserving the expected Streamline 1 interface. Frame generation is routed through the Streamline 2 path so DLSS Enabler can apply its MFG multiplier. On an RTX 4070 test system this produced roughly x3 frame generation, turning about 40 FPS into roughly 100 FPS at the same in‑game settings. This is a pre-release utility intended for users comfortable installing DLL-based graphics mods and running the included installer scripts. Targeted for RTX 40-series hardware, the bridge currently treats x3 as the practical ceiling; selecting x4 or higher in DLSS Enabler will not apply. The mod supports only DX12. If Steam verify or a game update restores witcher3.exe, rerun install.bat. Installation requires updating the game's DLSS DLLs to a 310-series build, installing DLSS Enabler 4.8.x using the dxgi.dll method, then copying this archive's bin\x64_dx12 contents into The Witcher 3\bin\x64_dx12 (files placed next to witcher3.exe include tw3bridge.dll, TW3 Streamline 2 Bridge.ini, install.bat, uninstall.bat, _mfgbridge_install.ps1, _mfgbridge_uninstall.ps1 and the sl2 folder) and running install.bat.
