Fishbattery FPS Optimizer

A lightweight Minecraft modpack focused on maximizing FPS and improving overall performance while keeping the vanilla gameplay experience intact.

This pack bundles well-known performance mods that improve rendering, memory usage, and game loading times. It is designed to run smoothly on both low-end and high-end systems while remaining stable across major Minecraft versions.

The modpack is maintained as the performance preset used in the Fishbattery Launcher. Updates to this pack ensure the preset stays compatible with newer Minecraft versions and performance mod updates.

Features

• Improved FPS and frame stability
• Faster world loading and reduced stuttering
• Optimized rendering pipeline
• Minimal gameplay changes (vanilla-friendly)
• Maintained for compatibility with major Minecraft versions

Intended Use

This pack can be installed like any normal modpack, but it is primarily maintained to power the FPS preset inside the Fishbattery Launcher, making it easy for users to keep their performance setup updated automatically.

Loaders

Fabric Forge Neoforge

Shader Support (Minecraft 1.12.2 and older)

Due to licensing restrictions, OptiFine cannot be distributed through Modrinth or included directly in this pack.

If you are using Minecraft 1.12.2 or older and want to use shaders, you will need to install OptiFine manually:

1. Download OptiFine from https://optifine.net/downloads
2. Place the OptiFine .jar file into the mods folder of your instance
3. Launch the game and enable shaders in the video settings

For newer Minecraft versions, shader support is handled automatically through supported mods.

Notes

Mods included in this pack remain the property of their respective authors. This pack simply bundles them for performance optimization and easier maintenance.

Forge 1.21.11 does NOT have any sodium or iris forks as of the latest release, so don't expect huge improvements on that version.
