DLSS-Unlocked
Unlock DLSS 3 Frame Generation (DLSS-G), Multi-Frame Generation (MFG: 2X, 3X, 4X), and Neural Rendering (DLSS-NR) features across NVIDIA GeForce RTX 20xx / 30xx / 40xx GPUs in DirectX 12 games. Fully compatible with Windows and Linux (Proton) out of the box.
[!NOTE]
Acknowledgments
This project is only made possible thanks to the extraordinary dedication of talented open-source developers.
Sincere gratitude and respect go to Artur Graniszewski for creating the revolutionary DLSS Enabler, OptiScaler, and Dagherbou for DLSS-NR forwarder research.
If you enjoy this project, please consider visiting their repositories, starring their work, and supporting their donation channels directly!
⚠️ Requirements
- Game that natively supports DLSS Upscaling and DLSS Frame Generation
- For Multi-Frame Generation to be enabled in the game's graphics settings, it must natively support the feature
✨ Features
- Multi-Frame Generation (MFG): Generate multiple interpolated frames (2X, 3X, 4X) via DLSS Enabler's headless frame generation pipeline.
- DLSS-G Frame Generation Bridge: Seamlessly translates NVIDIA Streamline DLSS-G calls to DLSS Frame Generation (with RTX 40 series GPU, only for the first generated frame) or AMD FidelityFX FSR 3.1 Frame Generation (RTX 20 and 30 series GPUs, all generated frames) via OptiScaler.
- Neural Rendering (DLSS-NR): Full support for Dagherbou's OptiScaler_DLSSNR upscaling backend and forwarder.
- Linux / Proton Support: Clean modular layout without recursive driver deadlocks.
- Dual Release Format: All-in-one automated Setup installer (
.exe) and clean standalone manual archive (.zip).
📦 Download & Installation
Get the latest release from the Releases page.
Option A: Automated Installer (.exe) — Recommended for Windows
- Download
dlss-unlocked-setup-*.exe.
- Run the installer and browse to your game's executable directory (e.g.
C:\Games\YourGame\bin\x64).
- Complete the installation wizard.
Option B: Standalone Package (.zip) — Recommended for Linux / Manual Installs
- Download
dlss-unlocked-standalone-*.zip.
- Extract the contents directly into your game's executable folder alongside the main game
.exe:
- Root folder:
dxgi.dll (rename to version.dll if using ReShade), OptiScaler.ini, nvngx.dll_dlssnr.dll, nvngx_dlssnr.dll (patched DLSS-NR)
OptiScaler/ folder: Companion modules (dlss-enabler-headless.dll, dlssg_to_fsr3_amd_is_better.dll, nvngx.ini, FidelityFX, XeSS, registry bypasses)OptiScaler/streamline/ folder: NVIDIA Streamline 2.14.1 runtime filesLicenses/ folder: Official licenses for NVIDIA Streamline, AMD FidelityFX, Intel XeSS, third-party libraries, and legal disclaimers
- (Linux) Launch a game with the following options:
WINEDLLOVERRIDES="dxgi=n,b" %command%.
🎮 Supported GPUs
- NVIDIA GeForce RTX 20xx / 30xx / 40xx
🚀 Automated CI Builds
This repository automatically tracks and synchronizes with upstream OptiScaler_DLSSNR:
- Checks for new releases every 3 hours.
- Packages the latest upscaler binaries, neural rendering forwarders, and companion libraries.
- Automatically builds and publishes both
.exe installer and .zip standalone manual packages on new releases.
🛠️ Building Locally
To build the standalone package or installer locally:
# 1. Download latest OptiScaler_DLSSNR and package standalone zip
.\build-optiscaler.ps1 -DownloadLatest -CreateStandaloneZip
# 2. Compile Inno Setup installer (requires Inno Setup 6.2+)
# Open "DLSS unlocked.iss" in Inno Setup Compiler and click Build
Known Issues & Troubleshooting
1. Overlay Crash on Linux / Proton (DirectX 12)
Some DX12 games may crash (VK_ERROR_DEVICE_LOST) under Wine / Proton when opening the OptiScaler in-game overlay menu:
- Fix: Set
OverlayMenu=false under [Menu] in OptiScaler.ini.
- Note: This allows the overlay to render via the game's internal render pipeline without crashing the Vulkan presentation queue, though the menu colors may be affected by the game's auto-exposure or tone-mapping. You can adjust colors or switch to a dark theme under Menu Theme and Color in the overlay.
Capcom's RE Engine enforces strict memory and swapchain integrity checks:
- Crash on Boot (
re9.exe!0x140000000...):
- Use
dxgi.dll as the proxy name and install REFramework (dinput8.dll) into the game root directory alongside dxgi.dll. REFramework safely hooks into the engine early and bypasses Capcom's VTable integrity checks.
- Frame Generation on RTX 20xx / 30xx GPUs:
- Set
FGInput=dlssg under [FrameGen] in OptiScaler.ini for rock-solid 2X Frame Generation.
- Multi-Frame Generation (MFG: 3X / 4X) can trigger race conditions with RE Engine's asynchronous worker threads; standard 2X (
FGInput=dlssg) is recommended for RE Engine titles.
