Immersive Optimization Mod designed to significantly improve server performance by implementing an entity tick scheduler. Unlike other optimization mods that may disable entity ticks entirely, this mod intelligently slows down and distributes ticks to reduce lag while keeping farms and distant entities functional. With up to 200% performance improvements, it’s ideal for modpacks and servers, especially those with heavy entity loads, and works well alongside mods like Entity Culling.

- Gradually reduces the tick rate of entities and block entities, achieving up to 200% performance boosts (e.g., 150% in Cobblemon 1.20.1 Fabric, 330% in a 700-mod pack) without disabling functionality.
- Distributes entity updates across multiple ticks to smooth out performance spikes, ensuring stable server operation.
- Automatically adjusts tick rates based on server load, optimizing performance in real-time.
- Provides /io commands for easy customization of tick scheduling settings to suit specific server needs.
