Adaptive Performance Tweaks: Spawn

A server-side module for Forge that significantly improves the mob spawning process in Minecraft. The mod offers intelligent spawn distribution, entity limits, and spawner optimization to maintain stable entity counts in the world.
Project Status ✅
The project is in a stable state with long-term support for the classic Forge version. Actively maintained and recommended for use in new modpacks. After more than three years of development, this classic variant has been thoroughly optimized and tested in various conditions. Critical fixes and compatibility updates will be released as needed.
