Description

MemoryLeakFix

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:

  • lazydfu - Makes startup much faster by not loading DFU until needed, also saves on memory
  • lithium-fabric - The best general performance mod
  • starlight - Re-write of the light engine to be blazing fast

My other optimizations/fixes
