I just wanted to make a small mod for my personal needs and the fact that I could never end a game because of extremely low speed from 41-42, leading to absolutely unplayable performance in 1945 bothered me. ( Just a personal thing, I dont like low speeds in Singleplayer )



So first what I did was limiting the AI to not build more than 200 Divisions ( just for an test ).

That alone gave me an huge performance boost, 1941 was nearly the same as 1936.

But in 1944 the performance went down anyways, not so hard as before, but too slow for me.



So I was wondering why. When I looked at Germany and Russia they had anyway much more Divisions than 200. At first i thought my mod didnt worked on later stages of the game, but then I saw that everything was fine, Germany didnt build more divisions than 200, but got additional 250 Expeditionary forces from Romania, Italy, Japan and smaller minors!

Russia also got 150 Divisions from Xinchinjang and other Asian minors ( quite too much isnt it ? )



So, for further testings i put expeditionary forces off for the AI.

That was mind blowing.

The first game in 200 Hours where I really "ended" the game.

Nearly no performance decrease, 1941 to 1950 is feeling like 1937 now ( nearly the same performance ). When Im playing on speed 5 its even too fast now, because all the popups from technology research and so on.

My first game where I researched jets, modern tanks and atomic bombs and could test them.



Somehow I was further on getting an fps decrease when selecting Air mode (F3) in 1945, but at the moment I go back to normal map mode, everything is ok. I think its because the AI is building further on extremely many planes and I didnt found a way to restrict the AI in building planes ( well somehow I found a way, but it works only for minor countries, majors are somehow hardcoded to build a lot of planes I think ).



But I dont understand why putting of expeditionary forces had so much influence. There were the same total amount of divisions in the game, only that countries like italy didnt gave them away to country B.



Btw it was mind blowing to see an extremely strong Italy in the game, they conquered Africa alone and extremely fast, all the invading tries from AI-UK in Italy in the early years got smashed from Italish forces.

In Vanilla I most often see "Rome has falling" in 1940, then germans have to come to help the italians with their own troops...



Side effect from limiting divisions is btw that the AI is now building up an sureplus of equipment when they have the assigned size and also had they updated 90% of all units to the latest template ( so standard 18 witdh infantry to the newer template which the AI is now building very well in beta patch), but in vanilla they hardly update the standard units to the newer templates, I think because they are always low of equipment in vanilla because they building divisions with no end, without waiting for having a good sureplus of equipment.

Sadly its not possible to mod the AI to just wait for having an bigger sureplus of equipment before building new divisions ( there is a define line, but paradox stated that it doesnt work anymore, because they had reworked how the AI works and I think its hardcoded now )



I was not sure If I should post this on Bug report forum.
