!lag™

!lag™ is a client-side Fabric optimization mod for Minecraft 1.21.11. It brings performance-focused graphics tuning, searchable settings, safe culling, particle limits, smooth zoom, and a lightweight FPS HUD into one clean client mod.

The goal is simple: make Minecraft easier to tune and smoother to play without changing gameplay logic or requiring anything on the server.

Highlights

  • Combined Video + !lag settings screen
  • Searchable settings with organized tabs
  • Safe entity and block entity culling
  • Distance and frustum culling controls
  • Particle budget limiter
  • Optional fullbright
  • Built-in FPS HUD
  • Smooth hold-to-zoom with scroll adjustment
  • Menu, overlay, unfocused, minimized, AFK, and deep-AFK FPS caps
  • Custom !lag startup loading screen
