NovaStack Performance Mod is a lightweight optimisation-focused mod for Minecraft 1.21.10 designed to improve performance in entity-heavy situations while keeping vanilla gameplay intact.
The mod primarily focuses on reducing performance impact caused by large numbers of mobs and dropped items.
🔧 Features
- Reduces unnecessary entity processing in high-density situations
- Lowers CPU usage during heavy mob activity
- Helps improve frame-time consistency in entity-heavy areas
- Designed to work alongside other optimisation mods
- Does not modify rendering behaviour
The mod does not force garbage collection (System.gc()), instead relying on the JVM’s built-in memory management for stability and compatibility.
