Proton Tools

Proton Tools

Anvil Organizer can launch external Windows tools (xEdit, Pandora Behaviour Engine, BodySlide, etc.) directly through the game's Proton prefix.

How to use

1. Click the Proton button in the toolbar (only visible for Steam games)
2. A dropdown menu shows all configured tools — click to launch
3. Select "Tools verwalten..." to add, edit, or remove tools

Adding a tool

1. Open the manage dialog (Proton button → "Tools verwalten...")
2. Click + and select the .exe file
3. Adjust name, arguments, or working directory if needed
4. Click OK to save

HiDPI / 4K Displays — Fix small fonts

On high-resolution displays (4K, etc.), Windows tools running through Proton may appear very small. This is because Wine defaults to 96 DPI.

Fix: Set Wine DPI scaling

1. Find your game's Proton prefix:

   ~/.local/share/Steam/steamapps/compatdata/<STEAM_APP_ID>/pfx/
   

   Common App IDs:

   • Skyrim SE: 489830
   • Fallout 4: 377160
   • Starfield: 1716740

2. Edit user.reg in the prefix directory:

   nano ~/.local/share/Steam/steamapps/compatdata/<STEAM_APP_ID>/pfx/user.reg
   

3. Find the line:

   "LogPixels"=dword:00000060
   

4. Change 00000060 (96 DPI) to your desired DPI:

   • 120 DPI (125% scaling): 00000078
   • 144 DPI (150% scaling): 00000090
   • 192 DPI (200% scaling, recommended for 4K): 000000c0

5. Save and restart the tool.

Note: This setting applies to all Windows applications running in that Proton prefix, including the game itself. If the game UI becomes too large, revert the change.

Troubleshooting

• Tool doesn't start: Make sure the .exe path is correct and the file exists.
• "not implemented" error: Some 64-bit tools have compatibility issues with Wine/Proton. Try the 32-bit version if available.
• Mouse/keyboard not working: Make sure you are using a recent Proton version (9.0+). Older versions may have input issues with some GUI frameworks.
