The AI Reducer mod is a server mod that will optimize the AI (intelligence) of mobs to increase the performance of the server with the game, the mod has settings and is especially recommended for mods in which a high density of mobs spawns.
Installing in a single-player game did not give me an obvious effect, but if you are running a server with a build, you can try this mod. The author recommends using the mod for mods such as Lycanites Mobs, Advanced Rocketry, Immersive Railroading, Ice, and Fire.
How to install the mod:
- Download the mod and place it in the mods folder of your Forge server.
- Installing it in a single-player game will likely have no effect, but you can try it.
