What does Universal Optimization add?
📌 English Description for Modrinth
- NOT COMPATIBLE WITH Starlight
Universal Optimization is a powerful tool designed to improve your server or singleplayer performance by drastically reducing the load caused by mobs.
This mod combines multiple advanced optimization techniques into one seamless system.
- It is recommended to use with Embeddium
- The speed effect works for flight
🧠 Main features:
- Removing mob collisions: Mobs do not collide with each other. This reduces CPU load and can even increase FPS. Improved version - slow movement bug fixed.
- In some cases, fixes prizes when moving from chunk to chunk:
- Caches some chunk data for quick access
- Speeds up recipes:
- Caches all recipes in the game, which can help avoid freezes when using JEI and EMI
- Also some other optimizations, caching in small ways
- Remote spawn limit: Mobs do not spawn further than a certain number of chunks from the player (default: 7 chunks). Fully customizable.
- Freeze mobs:
- Horizontal and vertical limit by X/Y
- Exceptions for mobs (eg Creeper, Phantom)
- Block and limit mobs:
- You can block or limit spawning of certain entities (
"minecraft:cow"or"minecraft:pig 5") - Global limit of all entities in the world (
AllMobsLimit = 100)
📁 Full Configuration Example:
You can find the full example configuration file below (scroll to the end of the description). All features are toggleable and adjustable to your needs.

📌 Русское описание для Modrinth
- НЕ СОВМЕСТИМ С Starlight
Universal Optimization — это универсальный мод для глубокой оптимизации производительности мира Minecraft за счёт уменьшения нагрузки от мобов и улучшения обработки сущностей.
- Рекомендуется использовать с Embeddium
- Эффект скорости работает при полете
🧠 Основные возможности:
- Удаление коллизий мобов: Мобы не сталкиваются друг с другом. Это снижает нагрузку на CPU и может даже повысить FPS. Улучшенная версия — баг с замедленным передвижением исправлен.
- В некоторых случаях фиксит призы при переходе из чанка в чанк:
- кэширует некоторые данные чанков для быстрого доступа
- Ускоряет рецепты:
- Кэширует все рецепты в игре, что может позволить избежать фризы при использовании JEI и EMI
- Так же еще некоторая оптимизация, кэширование по мелочи
- Ограничение дальнего спавна: Мобы не появляются дальше определённого количества чанков от игрока (по умолчанию: 7 чанков). Полностью настраивается.
- Заморозка мобов:
- Горизонтальное и вертикальное ограничение по X/Y
- Исключения для мобов (например, Крипер, фантом)
- Блокировка и лимит мобов:
- Можно блокировать или ограничивать спавн определённых сущностей (
"minecraft:cow"или"minecraft:pig 5") - Глобальное ограничение всех сущностей в мире (
AllMobsLimit = 100)
📁 Пример конфигурации:
Полный пример конфигурационного файла находится внизу описания. Все функции можно настраивать и отключать при необходимости.
