WitcherFGMod for RTX 50xx
DLSS Super Resolution + Multi Frame Generation (x2–x6) for The Witcher 3 Next-Gen
Brings NVIDIA Multi Frame Generation and modern DLSS upscaling to The Witcher 3
(v4.0.x, DX12). The game's built-in Streamline 1.5.6 tops out at 2x Frame
Generation —
Multi Frame Generation (x3–x6) is not possible with the stock
integration
. This mod loads NVIDIA Streamline 2.11 alongside it and routes
DLSS and Frame Generation through the modern runtime, unlocking MFG on
RTX 50 series
GPUs with full in-game control over the multiplier and
DLSS preset — no alt-tabbing into driver tools.
Features
- Multi Frame Generation x2–x6 — set the multiplier in WitcherFGMod.ini orlive in the in-game overlay.
- DLSS Super Resolution on the current DLSS 310 transformer model — anyquality mode (Quality / Balanced / Performance / Ultra Performance).
- In-game overlay on Page Down — multiplier, DLSS preset, live Host/GeneratedFPS and render → output resolution.
- Health check built into the overlay — detects the usual culpritsautomatically: HAGS disabled, in-game VSync, conflicting mods(ReShade / OptiScaler / DLSS Enabler / FSR3 bridges) and your GPU's realMFG cap vs the requested multiplier.
- Follows the game's own toggle — turn Frame Generation on/off in the in-gamegraphics menu and the mod follows it automatically.
- Selectable DLSS preset (J / K / L / M) for tuning image stability.
Requirements
- NVIDIA RTX 50 series GPU (Blackwell) with an MFG-capable driver, andHardware-Accelerated GPU Scheduling (HAGS) enabled in Windows.
- The Witcher 3: Wild Hunt v4.0.x, running in DX12 mode.
- Up-to-date DLSS 4 / 310-series (310.6) nvngx_dlss.dll and nvngx_dlssg.dllin your game's bin/x64_dx12 folder. Update them with DLSS Swapper if needed.
- A clean bin/x64_dx12 — remove other injectors (ReShade, OptiScaler,DLSS Enabler, dlssg-to-fsr3, any dxgi.dll/version.dll proxy). They hook thesame swapchain and conflict with the mod.
- NVIDIA Reflex enabled in-game is recommended for the best frame pacing.
Installation (manual — no installer)
- Back up your …/The Witcher 3/bin/x64_dx12/ folder first.
- In that folder, rename the original sl.interposer.dll tosl.interposer_real.dll (the mod forwards to it).
- Extract the archive into …/The Witcher 3/bin/x64_dx12/ — copysl.interposer.dll, WitcherFGMod.dll, WitcherFGMod.ini and thesl2\ folder (replace if asked).
- Copy your game's own nvngx_dlss.dll and nvngx_dlssg.dll (already inbin/x64_dx12) into the sl2\ subfolder.
- In game: set DLSS to any quality mode and enable Frame Generation in thegraphics menu. Set Reflex to On+Boost.
- Press Page Down in-game to open the overlay and pick your multiplier.
Full step-by-step and the expected folder layout are in INSTALL.md inside the
archive. To remove, follow UNINSTALL.md.
Troubleshooting
Flicker, stutter, or the multiplier won't change? Open the overlay
(
Page Down
) and check the
Health
section first — it flags HAGS,
VSync, conflicting mods and your GPU's MFG cap. A full checklist is in
INSTALL.md. If you report a bug, please attach
WitcherFGMod.log
from
bin/x64_dx12
— it now contains a
health_report
line that makes
diagnosis much faster.
Notes
- Higher multipliers (x4–x6) trade latency for smoothness; x4 is the sweet spotfor most setups. Use a frame rate close to your monitor's refresh.
- This mod does not modify game files — it sits beside them and is fullyreversible.
