The Problem: The "Barbary States" Glitch

The lag is not caused by your graphics card; it is a scripting issue. Specifically, the game engine struggles to process the turn for the Barbary States (the Ottoman protectorate). Because the Barbary States often have no legitimate government type or proper diplomatic standing coded into the start file, the AI loops infinitely while trying to calculate their move.

⭐ Tier 1: The Mandatory Fix – Script Removal (Works 100%)

This is the only fix that universally eradicates the lag without breaking your save game. DarthMod includes a campaign script that forces emergent factions (like the Ottomans) to spawn massive armies. By delaying or removing this script for the AI, you fix the lag.

Step-by-Step Instructions:

1. Navigate to your Empire: Total War data folder:
   • C:\Program Files (x86)\Steam\steamapps\common\Empire Total War\data
2. Open the campaigns folder.
3. Open the DarthMod folder (or DMUC if using Ultimate Commander).
4. Locate the script file named: scripting.lua
5. Make a backup. (Copy scripting.lua to your desktop. Do not skip this.)
6. Open the original scripting.lua with Notepad++ (or standard Notepad if desperate).
7. Press Ctrl + F and search for this exact line:
   -- DMUC Emergent Factions Script v1.4
8. Scroll down a few lines until you find the block of code starting with:
   local function OnWorldCreated()
9. Delete everything from local function OnWorldCreated() down to the line that says end just before the -- Custom script comment.
10. Save the file.

What this does: It removes the forced army-spawning script for minor factions. The Ottomans will still play normally but will no longer hyperventilate trying to manage 20 invisible reinforcement stacks. Result: Turn time drops from 90 seconds to 5–8 seconds.

3. Restart Empire. Let DarthMod’s launcher rebuild the preferences. Do not alt-tab during the first load.

7. Conclusion

The Ottoman turn lag in Empire: Total War – DarthMod is a legacy AI pathfinding bug amplified by mod features. It cannot be fixed 100% without rewriting the campaign AI, but the Turn Lag Submod + early Ottoman army culling reduces turn times from ~5 minutes to ~30 seconds in most cases. No known fix eliminates it entirely, but the above methods make the game fully playable.
