Unlock DLSS 3 Frame Generation (DLSS-G), Multi-Frame Generation (MFG: 2X, 3X, 4X), Intel Xe Frame Generation (XeFG), and Neural Rendering (DLSS-NR) features across NVIDIA GeForce RTX 20xx / 30xx / 40xx and Intel Arc GPUs in DirectX 12 games. Fully compatible with Windows and Linux (Proton) out of the box.

• 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

• Multi-Frame Generation (MFG) & XeFG: Out of the box, DLSS Unlocked primarily targets GeForce RTX 20 and 30 series GPUs (Turing & Ampere) via the native dlssg_sm86 unlocker. RTX 40 series (Ada Lovelace) users can easily switch to the Ada MFG unlocker (AdaMfgUnlock) directly via the OptiScaler in-game overlay or OptiScaler.ini. Intel Xe Frame Generation (XeFG) is also supported via the bundled XeFGUnlock plugin. DLSS Enabler headless is also bundled as an alternative companion option.
• DLSS-G Frame Generation Bridge: Seamlessly translates NVIDIA Streamline DLSS-G calls to native DLSS Frame Generation, Xe Frame Generation, or AMD FidelityFX FSR 3.1 Frame Generation via OptiScaler.
• Neural Rendering (DLSS-NR & Pre-SR Multipass): Full support for my OptiScaler-DLSSNR-PreSR-Multipass backend (based on wilsjo2), preserving native SM75/SM86 MFG unlocking, pre-SR multipass neural rendering, improved DLSS 5 compatibility, 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).

Get the latest release from the Releases page.

1. Download dlss-unlocked-setup-*.exe.
2. Run the installer and browse to your game's executable directory (e.g. C:\Games\YourGame\bin\x64).
3. Complete the installation wizard.

1. Download dlss-unlocked-standalone-*.zip.
2. 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, nvsmooth30.dll, dlssg_to_fsr3_amd_is_better.dll, nvngx.ini, FidelityFX, XeSS, registry bypasses)
   • OptiScaler/dlssg_sm86/ folder: Native Turing/Ampere MFG unlocker (dlssg_sm86.dll, dlssg_sm86.ini, THIRD_PARTY_NOTICES.txt)
   • OptiScaler/plugins/ folder: XeFG plugin (XeFGUnlock.asi, XeFGUnlock.ini)
   • OptiScaler/streamline/ folder: NVIDIA Streamline 2.14.1 runtime files
   • Licenses/ folder: Official licenses for NVIDIA Streamline, AMD FidelityFX, Intel XeSS, third-party libraries, and legal disclaimers
3. (Linux / Proton) Launch the game with the following launch options (required for native DLSS MFG via dlssg_sm86 in addition to the DLL override):

   WINEDLLOVERRIDES="dxgi=n,b" PROTON_ENABLE_NVAPI=1 PROTON_NVIDIA_NVCUDA=1 %command%

• NVIDIA GeForce RTX 20xx / 30xx (Turing & Ampere): Enabled out of the box with the bundled dlssg_sm86 native MFG unlocker.
• NVIDIA GeForce RTX 40xx (Ada Lovelace): Fully supported; can switch to the Ada MFG unlocker (AdaMfgUnlock=true) or native DLSS FG via the in-game overlay or OptiScaler.ini.

This repository automatically tracks and synchronizes with upstream OptiScaler-DLSSNR-PreSR-Multipass:

1. Checks for new releases every 3 hours.
2. Packages the latest upscaler binaries, neural rendering forwarders, and companion libraries.
3. Automatically builds and publishes both .exe installer and .zip standalone manual packages on new releases.

To build the standalone package or installer locally:

# 1. Download latest OptiScaler-DLSSNR-PreSR-Multipass 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

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.
