Put A Plug In It Mod focuses on fixing memory leak issues, optimizing memory usage, and improving compatibility between various memory-related mods in Minecraft. If your game stutters after long sessions or crashes with out-of-memory errors when running multiple mods, this patch addresses the root causes at the code level.
Available for Forge, Fabric, and NeoForge across Minecraft versions 1.18.2 through 1.21.11.
Key Features
- Memory leak fixes — Patches known memory leaks that cause Minecraft to consume increasing amounts of RAM over time, especially in modded environments.
- Memory usage optimization — Reduces baseline memory consumption so your game runs smoother with the same hardware.
- Multi-loader support — Works on Forge, Fabric, and NeoForge, increasing version and loader coverage for memory-related fixes.
- Cross-mod compatibility — Aims to integrate features and compatibility from other memory leak and optimization mods into a single solution.
- Biome temperature cache sharing — Optimizes how biome temperature data is cached and shared, reducing redundant memory allocations.
- Entity brain-memory cleanup — Cleans up entity AI brain-memory data that would otherwise accumulate and leak over time.
- TagKey weak intern pool — Uses weak references for TagKey interning to prevent tag-related memory buildup.
- Drowned navigation cleanup — Fixes a specific leak related to Drowned mob navigation data not being properly released.
- Crosshair target / hit result reset — Resets crosshair targeting data between frames to prevent accumulation.
- Screenshot buffer optimization — Frees large screenshot buffers on failure instead of holding them in memory.
