MemoryTune

MemoryTune is a lightweight Fabric optimization mod that aims to reduce memory overhead and improve performance stability without changing vanilla gameplay mechanics.

Features

• Monitors heap usage, GC activity, and runtime pressure
• Trims internal chunk/entity tracking caches when memory pressure increases
• Periodically cleans up stale chunk and world tracking data
• Uses object pooling for some temporary chunk metadata
• Disables clouds by default
• Dynamically lowers selected client graphics options when FPS stays low
• Culls some distant non-essential particles and particle emitters

Notes

Performance impact depends on your hardware, world, and mod setup. MemoryTune is focused on lightweight runtime optimizations and adaptive client-side reductions, not a full renderer rewrite.
