About this project
What does NumFlux add?
About ➗:




The typical performance boost is about 2–4%; however, if the server is heavily loaded with items, arrows (on the ground), or mobs within a large radius, the boost can reach 10% or more.
Features ✨:
- Fast math formulas
- Particle Fixes for Arrows
- Fixing the burning arrows
- Improvements to the mob despawn mechanism
- Minor improvements, the Zero-GC approach, and caches
This mod is a fork of GPUBooster and was created with the goal of separating server-side functions and moving the original exclusively to the client side.
Other my mods:
- GPUBooster(Client-side optimizations)
- MovieMaker(Content)
