In the game options, turn off the setting that shows AI movement. While this doesn't fix the pathfinding error, it prevents the game from rendering every single micro-movement, which can reduce a 15-minute turn to under a minute.
Here’s a focused, step-by-step guide to address the notorious in Empire: Total War (a problem where the Ottoman Empire’s turn takes 2–5+ minutes due to AI mismanagement of diplomats, imams, and unit spam).
Specifically, these mods implemented "AI behavior scripting" that prevented the minor nations bordering the Ottomans from making irrational moves that clogged the processor. They also "locked" certain units or standardized roster builds, reducing the computational load required for the AI to manage its armies. By decluttering the decision-making tree of the computer opponents, the turn times were drastically reduced, turning a ten-minute wait into a thirty-second process. empire total war ottoman turn lag fix
Taking control of the cities on either side of the strait removes the AI's ability to shuffle troops back and forth. If you don't want to keep the territory, you can give it to a protectorate or another faction like Greece.

In the modern era, further hardware solutions have emerged. As Empire: Total War is an older title, it relies heavily on single-core CPU performance. Modern overclocking and the use of "Large Address Aware" (LAA) patches—which allow the 32-bit application to utilize more than 2GB of RAM—have further mitigated the issue. When combined with a total conversion mod and modern hardware, the infamous Ottoman lag is effectively neutralized.
Furthermore, the internal mechanics of the Ottoman roster contributed to the issue. In the unmodded "vanilla" version of the game, the Ottomans possess a unit roster filled with unique, irregular units (Bashi-Bazouks, Deliler, and Cemaat Janissaries). The AI governing recruitment and army composition often struggled to prioritize effective builds, leading to stacks of units that would shuffle aimlessly around the map. This excessive pathfinding calculation, multiplied by the sheer number of enemies and rebel provinces surrounding the Ottoman starting position, created a bottleneck in the game's single-threaded processing engine.
