NovaStack Performance+

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.

📌 Notes

• Results will vary depending on hardware, settings, and installed mods
• Most effective in mob-heavy environments such as farms or grinders
• May have minimal impact in low-entity gameplay scenarios
• Designed to complement other optimisation mods rather than replace them
