OptiumUltra 1.0.0

First stable release of OptiumUltra.

OptiumUltra is a lightweight Fabric optimization mod designed to improve rendering performance while maintaining visual stability and compatibility with modern Minecraft environments.

Major Features

In-Game Settings (Mod Menu Support)

OptiumUltra now includes a full configuration screen accessible through Mod Menu.

You can configure performance settings directly in-game without editing config files.

Available settings include:

• Entity Culling
• Block Entity Culling
• Frustum Guard
• Shader Aware Mode
• Aggressive Optimization Mode
• Particle Limiter
• Distance Optimization Settings

Shader-Aware Optimization

OptiumUltra detects when shaders are active and automatically adjusts optimization behavior to avoid visual issues.

This helps prevent problems such as:

• invisible entities
• broken lighting
• missing particle effects
• rendering glitches

Smart Entity Culling

Rendering logic skips unnecessary entity rendering while ensuring important entities remain visible.

Entities that are never culled include:

• Players
• Named entities
• Leashed entities
• Riding entities
• Glowing entities
• Burning entities
• Very large entities

Block Entity Optimization

Block entities are intelligently filtered to reduce rendering load in dense areas.

Important block entities remain visible:

• Chests
• Barrels
• Shulker Boxes
• Beacons
• Ender blocks
• Spawners

Configurable Distance Optimization

Users can customize render distances for several entity types:

• Entities
• Block Entities
• Dropped Items
• Experience Orbs

This allows fine tuning for both low-end hardware and high-performance systems.

Stability Improvements

This release focuses on stability and compatibility.

Particle Crash Fix
