The “Ottoman Turn Lag” is a well-documented phenomenon where the AI faction Ottoman Empire takes excessively long (2–10+ minutes) to complete its turn. In DarthMod, this is exacerbated by increased unit variety, emergent factions, and the Ottomans’ unique strategic position (12+ starting regions, multiple land bridges, and constant agent spam). The definitive fix is a manual save file edit using ESF Editor to remove the Ottoman “World Ports” (trade ports with global range) — not by deleting units or using submods alone.

DarthMod multiplies the AI’s "thinking" time to prevent dumb moves. That’s great for challenge, terrible for your CPU. The result? The Ottoman turn takes longer than the previous 15 factions combined.
