10 Solutions for Fallout: London Crashes

1. Disable Decals

Start by launching the Fallout 4 launcher and going to the graphics settings. Look for the option labeled ‘Decals’ and turn it off. This fix seems to work best for users with NVIDIA RTX graphics cards. If you want a more reliable solution, consider the next option.

2. Turn Off Weapon Debris

In the graphics menu, disable the ‘Weapon Debris’ option. Many players have found that turning this setting off improves game stability without sacrificing too much immersion.

3. Install the Weapon Debris Crash Fix Mod

To avoid crashes related to weapon debris, download the Weapon Debris crash fix mod. This mod helps eliminate crashing issues without needing to lower your graphics settings.

4. Use Buffout 4 Mod

This method is a bit more complex. Follow these steps:

• Download Buffout 4, which is a recommended mod.
• Go to your Fallout 4 install folder, usually found at C:\GOG Games\Fallout 4 or Program Files (x86)/Steam/steamapps/common/Fallout 4. Replace the existing F4SE folder with the one from the Buffout 4 zip file.
• Create a shortcut for f4se_loader.exe on your desktop. Right-click it, go to Properties, then Compatibility, and check ‘Run as administrator’.
• Optionally, rename the shortcut to Fallout: London for easy access.
• Launch the game using this shortcut.

If you’re still crashing, you may need to try the other solutions as well.

5. Lower Graphics Settings

If the above steps don’t resolve your crashes, consider lowering your graphics settings. You can set everything to ‘Low’ temporarily or try these recommended settings for better stability:

• Resolution: Native (e.g., 1920×1080)
• Antialiasing: TAA
• Anisotropic Filtering: 16x
• Windowed Mode: Off
• Texture Quality: High
• Shadow Quality: High
• Shadow Distance: High
• Decal Quality: High
• Lighting Quality: High
• Godrays Quality: Medium
• Depth of Field: Standard (Low)
• Ambient Occlusion: SSAO (High)
• Weapon Debris: Off
• Screen Space Reflections: On
• Wetness: On
• Rain Occlusion: On
• Motion Blur: Off
• Lens Flare: On

6. Update Graphics Drivers

Make sure your graphics drivers are up to date. You can find the latest drivers on the NVIDIA or AMD websites, or use their software if it’s already installed on your computer.

7. Switch to Borderless Windowed Mode

Try changing the graphics option to ‘Borderless Windowed’ mode through the Fallout 4 launcher. This isn’t a perfect solution, but it has helped some players with crashes.

8. Disable ‘Read Only’ for Certain Files

Some Fallout 4 files may be set to ‘read only’, which can cause problems. Find the following files, right-click on them, and select Properties to uncheck the ‘Read Only’ box:

• CustomControlMap.txt (usually in C:\GOG Games\Fallout 4 or Program Files (x86)/Steam/steamapps/common/Fallout 4)
• f4se.txt (found in Data > F4SE)

9. Verify Mod Installations

If you’ve installed mods, ensure they’re in the correct folder. Instead of putting them in the Fallout: London folder, try placing them directly into the Fallout 4 folder (C:\GOG Games\Fallout 4\Data or Program Files (x86)/Steam/steamapps/common/Fallout 4\Data).

10. Adjust Config Files

You can tweak specific files to improve stability:

• BakaScrapHeap.toml: Located in C:\Program Files (x86)\GOG Galaxy\Games\Fallout 4 GOTY\Data\F4SE\plugins\. Change ScrapHeapMult = 2 to ScrapHeapMult = 4.
• config.toml: Located in C:\Program Files (x86)\GOG Galaxy\Games\Fallout 4 GOTY\Data\F4SE\plugins\Buffout4\. Change MemoryManager = true to MemoryManager = false.
• Fallout4Prefs.ini: Located in C:\Users\YOURNAME\Documents\My Games\Fallout4\. Change the values in the [NVFlex] section as follows:
  • bNVFlexEnable=0
  • iQuality=0
  • bNVFlexInstanceDebris=0
  • bNVFlexDrawDebris=0

Fixing Crashes After the Train Scene

One tip from the developers is to press ‘T’ during the logo animations after the train ride. Some players have reported that crouching and looking down as you enter the train also helps avoid crashes. Keep trying the suggestions in this guide, especially the ones related to Buffout and settings.

By following these steps, you should be able to reduce or eliminate crashes while playing Fallout: London. Enjoy your journey through the game’s immersive world!
