ONI Boost Kit — Parallel GC & Multicore (stutter fix)

Oxygen Not Included Performance Boost: Parallel GC & Multicore

Experiencing frustrating stuttering and lag in Oxygen Not Included, especially during complex colony management? This powerful mod, ONI Boost Kit — Parallel GC & Multicore, offers a robust solution to significantly smooth out your gameplay. Designed as a deep system enhancement, this mod tackles the periodic performance dips that can plague even powerful systems by optimizing how the game handles memory and processing tasks.

Understanding the Performance Bottlenecks

Oxygen Not Included relies on several core threads to manage its intricate simulation and rendering. While some aspects, like rendering and certain Unity jobs, are already designed to leverage multiple cores, critical components like the main game logic (duplicant AI, chore assignment) and the simulation itself (thermal conduction, fluid dynamics) primarily run on single threads. The game’s garbage collection process, responsible for managing memory, can also cause noticeable hitches. This mod specifically targets these areas to alleviate performance issues.

Key Enhancements Provided by the Mod:

• Parallel Garbage Collection: Recompiles the game’s garbage collector to utilize multiple CPU threads during its mark phase, drastically reducing memory management-related stutters.
• Multicore Unity Jobs: Increases the number of cores dedicated to parallelizable Unity jobs, such as animation skinning and culling, ensuring smoother visual processing.
• Performance Sentinel: An in-game notification system that confirms the mod’s successful integration and provides a quick status check of your performance enhancements.

How to Install for Maximum Performance

This mod requires a two-step installation process. First, subscribe to the mod through the game’s mod menu. Crucially, after enabling it, you must close Oxygen Not Included. Then, locate the mod’s installation folder and run the bundled installer script. This script, designed to be transparent and readable, performs the necessary system-level modifications. Once complete, relaunch the game. A confirmation message will appear if the installation was successful, indicating that the parallel garbage collection and multicore enhancements are active.

The installer includes safety features such as an engine gate to ensure compatibility with your current game version and automatic backups of critical game files. It also avoids overwriting modifications made by other tools and ensures that your save data remains untouched.
