BetterFps

BetterFps is a Minecraft modification that significantly enhances game performance while maintaining compatibility with most other mods.

Note: These screenshots are outdated, many improvements have been implemented since then.

Main Improvements

All mod features can be enabled or disabled through the configuration file (config/betterfps.json) or in the game options menu (Options → BetterFps Settings). In older versions, press F12 during gameplay to access settings.

Calculation Algorithms

Changes sin() and cos() calculation algorithms. There are 7 different algorithms available, each potentially affecting performance differently depending on your hardware. Unlike FpsPlus, this mod doesn't modify the game's base classes.

Works on both client and server.

Memory Optimization

Eliminates the pre-allocation of 10 MB of RAM. This feature was useful for players with modpacks where memory might be limited, but for users with sufficient RAM, it's unnecessary.

Client-side only.

Fog Removal

Completely removes in-game fog, which often causes lag and reduces FPS.

Client-side only.

Beacon Beam Optimization

Removes the transparent layer of the beacon beam, which can help when there are many beacons on the map.

Experimental feature — effectiveness being tested.

Client-side only.

Fast Hoppers

Hoppers in the original game work suboptimally, constantly checking for items even when unnecessary. The mod fixes this behavior — if there's a solid block above the hopper, it stops searching for items.

Server-side only.

Fast Beacons

Rewrites the unoptimized beacon code, processing only necessary calculations and significantly improving performance.

Works on both client and server.

Smart Search

Creative mode in large modpacks often freezes during item searches. BetterFps implements an intelligent search algorithm that reuses previous results and prevents search updates when non-alphanumeric keys are pressed.

Also supports multi-threaded/asynchronous searches, eliminating lag spikes during text input.

Client-side only.

Compatibility

• Optifine: Overrides fast math calculations if the algorithm is not set to "Vanilla"
• Fastcraft: Full compatibility
• FpsPlus+: BetterFps overrides FpsPlus sine and cosine improvements

Installation

For Minecraft Forge

1. Find the game installation folder
2. Place the mod file in the mods folder
