Threads Mod is a performance optimization mod for Minecraft that lets players manage the priority of game threads to reduce lag and improve stability. By tweaking thread priorities, you can address issues like frame rate instability, lag spikes during chunk loading, or low TPS on weaker CPUs.
Features:
- Customizable Thread Priorities: Adjust the priority for Render, Server, and Sound Engine threads to optimize performance.
- Lag Spike Reduction: Reduce chunk generation lag spikes by managing thread focus.
- Frame Rate Stability: Increase Render Thread priority for better FPS and smoother gameplay.
- Dynamic Adjustments: Use in-game commands or rejoin to apply changes.
- Background Thread Control: Adjust background thread priorities for additional fine-tuning.
