Plenty of people ask why their game keeps crashing after subscribing to this mod. This thread is meant to present the solutions found by the community so that you don't have to dig through the forums for answers! This is a quite large mod, especially with the submods and the amount of other mods merged into this. With that said, instability is a problem especially for those with slower devices.

"Is Darthmod compatible?" "Is Radius compatible?" "Is Weistrass-" NO. It is NOT COMPATIBLE . Large overhauls will conflict with this one. This game has its own overhauls to everything, from units, to economy, to buildings, etc. Submods change the game even further, so stick with the 100% supported submods within the UEFC collection, attached to the main mod.

To those playing MP, it's plagued with desynchs and crashes. I myself have no idea how to fix it.
No work around just yet as far as I know. There's too much content to patch and account for mp just yet.

Mods like Darthmod, Radious, or LordHendra cheat mods may leave residual data that interferes with other mods.

Recommended steps:

• Manually delete all Shogun 2 files.
  
• Uninstall the game via Steam.
  
• Unsubscribe from conflicting mods.
  
• Reinstall the game fresh.

Obliterate the files so you may start anew. I've had Darthmod values stay even when I unticked the mod.

1. Clear AppData
   
   • Go to: C:\Users\<YourUsername>\AppData\Roaming\The Creative Assembly\Shogun2
     
   • Delete everything inside that folder.
     
   • Also delete: TheCreativeAssembly\Launcher
     (This resets the launcher and may fix load order issues. It’ll be redownloaded when you launch the game.)
     
2. Launch Shogun 2 normally.
   
   • Reorder your mods in the mod menu as needed.
     
   • The load order of the mods is the same order they are placed within the UEFC collection
     
   • PLEASE read the descriptions of any and all submods. Not every submod is compatible
     with one another, and some change the game heavily.
     
3. Verify in-game settings
   
   • Check video memory and unit counts via game settings and custom battles.
     
   • Within setttings, at the bottom is a video memory counter
     
   • If said video memory counter is suspiciously low, game isn't utilizing it properly.
     
   • If values seem off, move on to the next section.
     

Is your video memory dirt low despite your expensive gaming rig? Have no access to ULTRA unit sizes? This part will allow you to fix that, and maybe give you more fps! This is also the most important part, as the lack of utilized video memory seems to be the cause of most crashes.

1. Navigate to: C:\Users\<YourUsername>\AppData\Roaming\The Creative Assembly\Shogun2\scripts. It should have redownloaded after clearing.
   
2. Open the preferences.script.txt file. This is where everything happens.
   
3. Use Ctrl+F to find and edit these variables:
   
   | Variable |Default Value | Recommended |
   | "gfx_video_memory" |Default:0 | -2000 |
   | "number_of_threads" |Default:0 | Match CPU Core count |
   | "campaign_unit_multiplier" |Default:1.0 | 1.5 (optional) |

They will have a number next to them within the text file, followed by a semicolon (;).
ex: gfx_video_memory 0;
Set said number to the recommended.

Change gfx_video_memory to -2000 uncaps it, so the game can use more.

Changing number_of_threads improves multithreading and reduces single-core bottlenecks (although reportedly the game is meant to only use one core. It's just that it's said to improve performance overall for some). To find CPU core count, go to task manager (Ctrl+alt+Delete) and go to Performance>CPU>Cores (found at the bottom).

Changing campaign_unit_multiplier allows you to control the game's unit size modifier. Increasing it to 1.5x allows you to ignore the 1.5x submod, which also edits some other things that can destabilize your game. DO NOT CHANGE UNIT SIZES IN-GAME OR IT WILL REVERT. 1.5x may cause crashes so it may be best you keep the sizes at 1 and then set your ing-game settings to ULTRA unit sizes.

• Colorful Flags Submod: Known to cause crashes. Try disabling it if it bugs out for you.
  
• Sandbox Submod: Makes everything crazy cheap, alters values. May cause crashes. Non-compatible with the More Fun Ships submod.
  
• 1.5x Submod: May introduce buggy starting units. Instead use the campaign_unit_multiplier edit as said before.
  
• Strongholds of the Samurai: Popular mod that adds new maps. High-end/ well performing devices can run it, but has reportedly caused CTDs for others. Use at own risk.
  

Device specs: Lower-end systems may struggle with large-scale mods. UEFC has multiple, especially Expanded Japan, which was laggy on its own.

AI navy behavior: Fleets often refuse to merge, causing performance strain.

AI army behavior: Similar issue, but less severe due to unit caps.
