Memory Leak Fix

Memory Leak Fix

Memory Leak Fix

A mod that fixes multiple memory leaks in Minecraft. Both server-side & client-side

For the best performance & memory usage, I recommend using this mod with:

- lithium-fabric - The best general performance mod

- FerriteCore - Memory usage optimizations

My other optimizations/fixes

MoreCulling - Changes how blockstate culling is handled to improve performance

Carpet-Fixes - Largest Server-Side bug fixing mod

Blanket - Client-side tweaks/fixes

RailOptimization - Make powered rails less laggy

Minecraft 1.20.5+

All the memory leaks in minecraft previously fixed by MemoryLeakFix have been fixed. Making this mod obsolete in future versions of the game.
