Frequently asked questions

How do I turn on the entity tick scheduler?
Open the mod menu and locate Immersive Optimization Edition in your active mods list. The entity-tick-scheduler is enabled by default, so it starts working immediately when you load a world—you don't need to configure anything to get the performance boost.
What exactly does the entity tick scheduler do?
It spreads out how often mobs, animals, and items update their behavior across multiple game ticks instead of all updating at once. This prevents the sudden lag spikes that happen when too many creatures try to move, attack, or process at the same time.
Will this mod affect mob behavior or make them act weird?
No—mobs will behave normally from your perspective because the scheduler only changes *when* they update, not *how* they behave. You'll see smooth mob movement and normal AI, just without the stuttering.
Can I use this mod with my large mob farm?
Yes, this mod is specifically designed to handle farms with many mobs. It prevents the lag spikes that normally occur when hundreds of creatures are crammed into one area, letting your farm run smoothly without tanking your TPS.
