Too Many Entities Mod (1.21.8, 1.20.1) – Minecraft Performance Optimization for Mob-Heavy Worlds

Too Many Entities Mod (1.21.8, 1.20.1) is designed to improve performance in mob-dense Minecraft worlds by placing display limits on how many entities (mobs) can appear on screen at once. While Minecraft’s flexibility allows for large-scale mob farms and dynamic environments, too many active mobs can heavily impact FPS especially on lower-end systems. With this mod, you can control visibility without altering actual gameplay mechanics, as the hidden mobs still exist and function behind the scenes.

Features:

Per-Entity Limit Controls: Customize how many of each mob type (e.g. zombies, cows, villagers) are allowed to visually render at once.
FPS Boost: Reduces graphical load without affecting mob behavior or spawns, preserving redstone contraptions and farms.
Invisible Overflow: When limits are exceeded, extra mobs are hidden from view but remain active in the world.
Lightweight Performance Aid: Especially useful for modpacks or servers with mob overpopulation or automation-heavy builds.
Low-End System Friendly: Perfect for improving gameplay on machines with limited processing power or older graphics cards.
