100% Optimization Focused

We built this modpack with extreme simplicity in mind since we have been looking for something like this ourselves. Unlike with most other packs, you will find:

• NO unnecessary quality-of-life mods.
• NO visual enhancements.
• NO content additions or random mods.

Key Features

🚀 2x Faster Chunk Loading: Seamless gameplay with multi-threaded chunk generation and a completely rewritten lighting engine. Whether you are teleporting or flying with an Elytra, the world loads faster than ever by utilizing all available CPU cores instead of relying on a single thread.

💾 Reduced RAM Usage: Using advanced memory management and data storage, this modpack lowers the RAM required to run the server. This prevents "Out of Memory" crashes and allows you to host a smooth experience even on budget hardware.

⚡ Optimized TPS & MSPT: By rewriting core game physics, entity tracking, and mob AI logic, this modpack makes sure your server processes ticks efficiently. Resulting a stable 20 TPS and low MSPT, allowing for complex redstone contraptions and higher player counts.

🌐 Smoother Networking: Optimized network stacks and packet compression reduce the bandwidth usage between the server and players. This minimizes rubber-banding and hit-registration issues, ensuring a responsive experience for everyone.

✅ Full Vanilla Compatibility: All optimizations are strictly internal code improvements that respect vanilla mechanics. Players can join with a standard vanilla client, no extra downloads required on their end.
