Max FPS booster (Fabric 26.3)

Max FPS booster is an ultra-high-performance optimization mod and customizable FPS HUD for Minecraft: Java Edition 26.3 ("Wilderness Bound"), built natively on the Fabric ecosystem.

Designed from the ground up by modclaim to operate in complete synergy with Sodium, Max FPS booster eliminates performance bottlenecks across entity rendering, block entity extraction, particle budgets, animated texture uploads, and singleplayer/LAN host server tick lag.

⚡ Key Features

📊 Dynamic Color FPS Overlay HUD

• Real-Time Display: Live framerate counter rendered smoothly on your screen.
• Dynamic Color Shifting:
  • 🟢 Green (#55FF55): >= 60 FPS (Smooth performance)
  • 🟡 Yellow (#FFFF55): 30 - 59 FPS (Moderate framerate)
  • 🔴 Red (#FF5555): < 30 FPS (Low framerate warning)
• Customizable Screen Corner: Top-Left (Default), Top-Right, Bottom-Left, or Bottom-Right.
• Performance Diagnostics: Optional Min/Max FPS tracking and live frame time in milliseconds (e.g. 6.8 ms).
• Clean F3 Integration: Automatically hides when opening the full vanilla F3 debug overlay.

🚀 Advanced Rendering Optimizations

• Entity Distance Culling & Scaling: Culls distant entities outside player view or beyond configured distance multipliers before expensive model evaluation and matrix calculations.
• Block Entity Culling: Skips rendering of heavy block entities (chests, shulker boxes, beacons, banners) located beyond configured view distances.
• Particle Throttling & Culling: Prevents out-of-range particles (torches, campfires, portals, weather splashes) from polluting memory or running tick updates.
• Animated Texture Throttling: Paces animated texture updates, significantly lowering GPU upload strain while keeping animations looking natural.

🌐 LAN Host & Singleplayer Server Optimizations

• Smart Mob Ticking: When hosting a LAN world or playing in singleplayer, distant inactive mobs without targets are throttled to skip redundant AI goal selector ticks, drastically freeing up CPU headroom and lowering MSPT.
• Auto-Save Lag Spike Reducer: Prevents micro-stutters and sudden freeze frames during periodic world saves by smoothing chunk flush routines.

⚙️ ModMenu In-Game Settings

• Built-in native configuration screen accessible via ModMenu (optional dependency).
• Instant Hot-Reload: Every toggle and slider takes effect immediately upon adjustment—no client restarts required.
• Persisted cleanly to .minecraft/config/max-fps-booster.json.
