Mods that Made this game Playable for me

1. Cao Cao AI Scheme Disable
   https://steamcommunity.com/sharedfiles/filedetails/?id=2470770758

This is #1 mode I would need to play this game.
Reason for this mode:
Cunning Scheme happening every turn, I would rather not play this game
without this mode.

2. Upkeep for units -50%
   https://steamcommunity.com/sharedfiles/filedetails/?id=2982934070

This is the first mode I had to install.
Unit upkeep was way too high for a small start.

3. No Building Requirements for Reforms

It is very annoying that I have to Temporally build a building that I don't want
just for research. This is the fix for that.

I've noticed having battles with 4 armies cause massive lag with this mode,

without this mode installed, the problem was solved.

2.

This mode does not even require me to have a large army.
It just lags in battle.

poorly optimized units obviously.

Conclusion: If your battle lags, try without these two mods and it might run fine.
Also, you will have to restart a new campaign to play without these mods.
