Async - Minecraft Entity Multi-Threading Mod ⚙️

Async is a Fabric mod designed to improve the performance of entities by processing them in parallel threads.

Important❗

Async is currently in alpha testing and is experimental. Using it may lead to incorrect behavior of entities and crashes.

What is Async? 🤔

Async is a Fabric mod designed to enhance entity processing performance. The mod leverages multithreading, which allows multiple CPU cores to be used to improve performance when there are large numbers of entities.

💡 Key Benefits:

  • ⚡ Improved TPS: Maintains stable tick times even with large numbers of entities.
  • 🚀 Multithreading: Utilizes multiple CPU cores for parallel entity processing.
