Efficient AI (Better AI, No Lag)

Are you tired of the terrible vanilla AI? Do you suffer from lag? If you do, this is the mod for you!

This mod makes the AI much better by improving the AI's construction, production, templates, research, political power usage, national focus order (with Historical AI Focuses ON), front management, use of planes, peace deals and lots of other small things.

Every country (with a National Focus tree) is given its own unique strategy, based on a semi-historical scenario. These strategies are optimzed for a WW2 that starts in late 1939. For best effect, it's therefore recommended to wait untill 1939 before starting WW2. This mod should be played with Historical AI Focuses on.

28 countries are removed from the map (and sometimes their industry to not effect balance). The removed countries are mostly countries that were not historically relevant to WW2, or were too small to make a noticeable difference. This noticeably improved performance, as well as the AI in some cases. This mod also changes the starting Land Doctrines of quite a few countries.

This mod rebalances the following things (list does not include changes to AI):
  • Starting Land Doctrines of some countries
  • Starting units of all majors and most minors. The equipment used should remain almost exactly the same.
  • Nerfed Generic National Focus tree. Removed 2 Civilian Factories, 1 Dockyard and 2 Infrastructure.
  • Colony states no longer have reduced number of building slots (to match occupied/cores).
  • Removes 28 countries.

Any feedback is very welcome!

Nope, not compatible with Road to 56.

It should be compatible with mods that create new states as long as the changes dont overlap with what I've changed. Anything in Europe will probably work, but South America and some parts of the rest of the world wont.

Is this compatible with any mods that create any new states, and/or Road to 56?

Thank you.

> Is it save game compatible?

It is. But, the AI improvements and lag reduction won't have full effect unless you start a new game.

There, the game should run quite a bit smoother now.

The patch notes can be seen in the Change Notes above.

@ diademic111

The starting unit rebalancing should help the performance quite a bit, but it'll have a bigger effect on the early-game. However, you should still have a noticeable performance improvement even in the late-game.

It'll remove about 50% of the starting units (maybe 300 divisions) by removing all garrison, all cavalry and low equipment % infantry units, and then using the equipment to add full strength (100% equipment) infantry.

It should be on steam in ~24 hours, but you'll need to start a new game for the changes to take effect.

well I hope this helps my games performance.. everything works great until about 1941 then the game just crawls to a halt... cheers

The mod should now be back to roughly the pre 1.5.0 level of AI improvements. The only things missing should be unique idea priorities for each country, and the starting unit rebalancing (which is mostly for improved performance).

After that, I'll work on improvements for east asia.
