📋 About This Mod
ULG (Ultra Low Graphics) Tool
This tool aims to improve performance on old/weak desktops and laptops. It sets many of the graphics settings below the default low limit. This should help increase performance on older computers or laptops. I have seen an average improvement of about 5fps.

✨ Key Features
📊 Pros & Cons
✅ Pros
- Huge community trust with 8,322 endorsements and 319,291 downloads.
- Simple INI tweaks that can give a solid FPS boost without needing a new GPU.
- Straightforward setup—just drop in the files and go.
⚠️ Cons
- Last updated in March 2021—might not be tuned for the latest game patches.
- Visual quality takes a hit: shadows, godrays, and draw distances are reduced.
- No detailed documentation on which specific INI settings are changed or how to customize them.
For players on older or low-end PCs who want to squeeze out extra frames in demanding areas. Also great for competitive players who prioritize performance over eye candy. Skip if you're on a high-end rig and care about visual fidelity—this will make the game look noticeably worse.
💡 Beginner Tips
- Make sure to back up your original INI files before replacing them, so you can revert if needed.
- If the mod doesn't work as expected, check that you're placing the INIs in the correct directory (usually the game's root or config folder).
- Combine with a mod manager like Vortex or MO2 for easier installation and uninstallation.
