BetterFps Mod — Guide

Performance Features

Beyond math optimizations, BetterFps introduces several specific fixes for common lag sources in Minecraft.

• Memory Preallocation Removal: By default, Minecraft pre-allocates 10MB of RAM to prevent the game from crashing immediately on low-memory systems. BetterFps can disable this, freeing up that memory for actual game use, which is particularly beneficial for large modpacks.
• Fog Removal: Rendering fog can be surprisingly taxing on the GPU. BetterFps provides a toggle to completely disable fog, which can provide a noticeable FPS boost in biomes like swamps or during rainy weather.
• Fast Hopper: Hoppers in vanilla Minecraft are notorious for causing "TPS lag" because they constantly check for items to pick up even when they are full or blocked. BetterFps optimizes this logic, reducing the CPU load of large hopper arrays.
• Fast Beacon: Optimizes the code responsible for beacon effects and beam rendering. It removes unnecessary calculations and simplifies the beam's transparency layers to reduce rendering overhead.
• Faster Creative Search: In large modpacks with thousands of items, the Creative Mode search bar can cause the game to freeze. BetterFps implements a smart search algorithm that caches results and ignores non-character keys (like Shift), making the search instantaneous.
