🚀 What is FrameBridge?

FrameBridge takes the amazing core engine from OptiScaler and integrates it with a fully automated, user-friendly CI/CD pipeline and an "all-in-one installer" philosophy.

Instead of dealing with multiple DLLs and manual file placements, FrameBridge provides a compiled installer that correctly drops the necessary files (nvngx.dll, version.dll, dxgi.dll, etc.) directly into your game folders, bridging upscalers and frame generation mods seamlessly.

⚙️ Supported Technologies

FrameBridge enables you to swap and mix the following technologies regardless of your GPU vendor (NVIDIA, AMD, or Intel):

• Upscalers Supported:
  • NVIDIA DLSS (Deep Learning Super Sampling)
  • AMD FSR (FidelityFX Super Resolution)
  • Intel XeSS (Xe Super Sampling)
• Frame Generation:
  • DLSS-G to FSR3 (via Nukem9's mod integration)
  • OptiScaler's native Frame Gen wrappers

💿 Installation Guide

Installing FrameBridge is straightforward thanks to the included Inno Setup package.

1. Go to the Releases tab.
2. Download the latest framebridge-setup-X.X.X.exe.
3. Run the installer and point the Installation Directory to your game's executable folder (where the main .exe or current nvngx.dll is located).
4. Select your preferred injection method (e.g., version.dll for general compatibility, or dxgi.dll).
5. (Optional) Check the box for "Experimental support for AMD and Intel GPUs" if you don't own an RTX card.
6. Click Install!

🔧 Configuration

After installation, you can tweak the settings to your liking by editing the OptiScaler.ini file located next to the game executable.

Some common settings you might want to adjust:

• [UpscaleRatio]: Override the game's default quality presets.
• [XeSS] or [FSR]: Force the use of a specific upscaler backbone.
• [FrameGeneration]: Toggle the frame generation module on or off.

Tip: If the game crashes on startup, try changing the injection method by renaming version.dll to winmm.dll or reinstalling using a different option.

🛠️ Troubleshooting & FAQ

• The game doesn't launch after installing!

  • Try deleting version.dll and using the installer to inject via dxgi.dll or winmm.dll. Some games have anti-cheat or specific loading patterns that conflict with version.dll.

• Can I use this on multiplayer games?

  • No. We highly advise against using FrameBridge or any DLL injectors in multiplayer games with Anti-Cheat (like EAC or BattlEye). You will likely get banned.

• DLSS Frame Generation option is greyed out in-game?

  • Make sure you installed the "DLSSG-to-FSR3" module during the setup (enabled by default) and that your Windows Hardware Accelerated GPU Scheduling (HAGS) is turned ON.
