Pyradium (Forge)

Pyradium is a multifunctional mod for optimizing Minecraft performance, created from an unofficial fork of Lithium for the Forge platform. The main goal of the modification is to significantly improve the overall game performance (mob AI, physics, chunk loading, and other aspects) without changing the game mechanics.

Key Benefits

45% performance improvement thanks to optimization of server tick processing times. The mod functions independently on both client and server, allowing it to be installed on the server without requiring all players to have it installed.

Even in single-player mode, the game uses an "integrated server" that processes the game world. Optimizing the server-side frees up the computer's processor for other operations, ensuring increased frame rates and improved interface responsiveness. In multiplayer servers, the mod enables successful operation with a large number of active entities, chunks, and players on standard hardware.

Key Optimization Features

Physics

Improved collision detection system between objects by simplifying algorithms for simple-shaped blocks. The new approach significantly reduces the number of blocks checked each tick, especially during rapid object movement.

Mob AI

An event-based system has been implemented for some processes, reducing CPU load associated with constant polling of game state. The redesign of mob brains has made the selection between AI tasks much faster compared to the standard version.

World Generation

Removed unnecessary calculations during world generation, simplified algorithms for temporary data structures of block palettes, which significantly increases world loading speed and minimizes TPS drops during map exploration.

Mob Farming

Optimized object collision recognition due to the fact that it occurs between simple blocks. Mob farms now cause significantly less damage to server performance.

Block Mechanics

Block updates after chunk creation and redstone mechanisms work faster by eliminating redundant calculations. The time to determine complex block tasks has been reduced from a power function to a constant, reducing latency when working with multiple blocks.

Explosions and TNT

Improvements have been implemented in the ray tracing algorithm: the same cached result is used for multiple steps across an occupied position, reducing delays without changing the explosive behavior. A new movement tracking algorithm is applied.

Mob Navigation

Important settlement points for villagers and raiders are determined 16-22 times faster by replacing stream decomposition with a productive iterator loop.

Redstone Popularity

Rail dust power level calculation has been optimized with reduced checks, reducing 35% of redstone operation delay under the same logic.

...Additional internal improvements with accelerated JVM code compilation and startup in a fraction of the time.

Compatibility and Installation

Pyradium is compatible with Minecraft Forge starting from version 1.16.5. Make sure the latest Forge build is used. To install the mod, load the file into the mods directory—no additional changes or components are required.

Development

This is a free open-source project. Users can include it in their modpacks.
