Addoners Optimizer

Addoners Optimizer is a client-side performance mod for Minecraft 1.26.1.2 (Fabric) that dynamically adjusts selected video settings based on real-time FPS measurements to help maintain smoother and more stable gameplay performance.

How it works

The mod samples the player's FPS every second using a rolling average and applies one of three optimization levels:

• LOW (≥80 FPS) — minimal adjustments, prioritizing visual quality
• MEDIUM (50–79 FPS) — moderate reductions to selected graphics settings
• AGGRESSIVE (<50 FPS) — stronger reductions intended to improve frame stability on lower performance systems

A 3-second cooldown between changes helps prevent rapid setting fluctuations.

Features

• Automatically adjusts:

  • Render distance
  • Particle settings
  • Smooth lighting
  • Shader quality settings

• Optional status HUD displaying:

  • Current FPS
  • Active optimization level
  • Shader detection state

• Shader-aware mode:

  • Reduces optimization aggressiveness when Iris or Canvas shaders are detected

• .addoners profile system:

  • JSON-based profiles for hardware tiers or shader packs
  • User-customizable optimization rules

• Built-in profiles for:

  • Quartzglow Shaderpack
  • Skygleam Shaderpack

• In-game configuration support through Mod Menu

• Structured debug logging to logs/latest.log

Adjustable settings

Depending on the active optimization profile, the mod can dynamically modify:

• Render distance (2–32 chunks)
• Particle settings
• Smooth lighting
• Shadow quality levels
• Shader toggles through profile rules

Requirements

• Minecraft 1.26.1.2
• Fabric Loader 0.18.6 or newer
• Fabric API
• Java 25+
• Mod Menu (optional)

Configuration

Config location:

%appdata%/.minecraft/config/teamaddoners/modconfig.json

Profiles folder:

%appdata%/.minecraft/config/teamaddoners/profiles/

No manual setup is required. The optimizer starts automatically when Minecraft launches.

Performance notes

Performance impact and effectiveness may vary depending on:

• Hardware specifications
• Installed mods
• Shader packs
• World complexity
• Render resolution
• Server load

Testing was primarily performed on systems using Fabric with Sodium-based rendering environments under varying render distances and shader configurations.
