Opsidian+

Opsidian+

Overview

Opsidian+ is a high-performance Minecraft optimization modpack for Minecraft 1.21.11 Fabric, combining the performance-focused foundation of Opsidian with a carefully selected collection of essential quality-of-life and utility features.

While the original Opsidian is designed around pure performance and maximizing frame rates, Opsidian+ is built for players who want an optimized Minecraft experience without having to install their favourite essential mods separately.

From improved rendering and reduced stuttering to minimaps, world maps, food information, and other everyday utilities, Opsidian+ gives you a more feature-rich Minecraft experience while keeping performance at its core.

Features

• High-Performance Foundation

Opsidian+ retains the carefully tuned optimization systems found in the original Opsidian.

Mods such as Sodium, Lithium, Entity Culling, More Culling, and BadOptimizations work together to improve rendering efficiency, reduce unnecessary processing, and provide smoother frame times.

The result is an optimized Minecraft experience designed to make the most of your available hardware.

• Essential Quality-of-Life Features

Opsidian+ adds a selection of useful features that improve everyday gameplay without fundamentally changing Minecraft.

This includes utilities such as Xaero’s Minimap, Xaero’s World Map, AppleSkin, and other carefully selected quality-of-life additions.

These features are designed to be useful rather than intrusive, giving you information and functionality that would otherwise require installing several separate mods.

• Shader and Visual Support

Opsidian+ retains the visual compatibility of the original Opsidian, including Iris for shader support and Continuity for connected textures.

You can use shaders and visual enhancements while still benefiting from the performance improvements provided by the optimization foundation.

• Smart Rendering

Culling systems such as Entity Culling and More Culling prevent Minecraft from spending resources rendering objects that cannot be seen by the player.

This can be particularly useful in areas containing large numbers of entities, complex structures, or dense environments.

• Faster World Loading

The optimization foundation helps improve chunk loading, world generation, and game logic, reducing unnecessary stuttering while exploring and loading new areas.

• Multiplayer Friendly

Opsidian+ is suitable for both singleplayer and multiplayer gameplay.

The added features are designed to complement normal Minecraft gameplay rather than fundamentally alter it, making the pack suitable for everyday worlds and multiplayer servers.

What’s Different From Opsidian?

• Opsidian is focused almost entirely on performance.

• Opsidian+ keeps that performance foundation while adding the essentials.

• Opsidian Creator takes that performance foundation and builds on it with powerful tools for builders, content creators, and technical players.

Opsidian+ is therefore intended for players who want optimized Minecraft with useful features, rather than a completely vanilla experience.

Opsidian+ is designed to remain efficient without requiring large amounts of allocated memory.

For the best performance, users should adjust render distance, simulation distance, shader settings, and other graphics options according to their hardware.

Ideal For

Players who want optimized Minecraft with useful extras
Older and lower-end laptops
Integrated graphics systems
Budget desktop PCs
Players who regularly use minimaps and world maps
Survival players
Multiplayer players
Players who want quality-of-life features without installing a large modpack
Anyone who wants more functionality than the original Opsidian while retaining its performance focus
Design Philosophy

Opsidian+ follows three principles:

• Performance First

The optimization foundation remains the most important part of the pack. Additional features should not unnecessarily compromise performance.

• Useful, Not Bloated

Every additional mod should provide a clear benefit. Opsidian+ is not intended to become a collection of every popular Minecraft utility mod.

• Vanilla, But Better

Opsidian+ aims to enhance Minecraft rather than replace it. The goal is to provide the features players commonly want while keeping the familiar Minecraft experience intact.

Optional Performance Tip

Some optimization mods included in Opsidian+ can take advantage of Java’s Vector API (SIMD) for additional performance.

If your launcher supports custom JVM arguments and you are using a compatible Java version, you can enable it by adding:

–add-modules=jdk.incubator.vector

If you do not add this argument, Opsidian+ will still work normally. This option simply enables additional CPU optimizations where supported.

Performance Notice

All FPS values shown in the gallery were recorded on the developer’s hardware. Actual performance will vary depending on your hardware, graphics settings, shaders, and other installed mods.

Opsidian+ is for players who don’t just want Minecraft to run better — they want Minecraft to have the essentials built in while keeping that performance foundation intact.
