Description

CatModOPti

CatModOPti is a lightweight, vanilla-friendly modpack designed to give your game a massive performance boost without losing the classic Minecraft feel. Whether you're playing on a "potato" PC or a high-end rig, these mods ensure your frames stay high and your game stays cool.

It was made with Performance First in mind, built on the Fabric loader for the best possible frame rates and modern compatibility.

Mod Highlights

To keep your game purring, we’ve included the gold standard of optimization:

  • Sodium – The engine that makes your FPS skyrocket.
  • Lithium – Optimizes game logic (mobs, physics) so your CPU can relax.
  • FerriteCore – Squeezes down memory usage so you can play with less RAM.
  • ImmediatelyFast – Speeds up rendering of chests, signs, and entities.
  • and MORE!

📊 Performance Sheet

See the "purr-formance" boost for yourself! These are the average results from our testing:

Setup Type Vanilla FPS CatModOPti FPS Improvement Low-End (Potato) 20-30 FPS 60-90 FPS 3x Faster! Mid-Range PC 80-120 FPS 250+ FPS 2x Faster! High-End Rig 200 FPS 500+ FPS Silky Smooth

Pro Tip: The lower the render distance the more fps you get
