  • Flecky's Crystal Optimizer

The optimization mod for Crystal PvP and Anchor PvP – for faster, smoother and more responsive gameplay.

CrystalOptimizerSync makes placing crystals, breaking crystals and igniting anchors feel instant, without the annoying server delay. On top of that come handy performance options for more FPS in big fights.

100% client-side and no cheat – no reach, no damage changes, no combat automation and no modified or extra packets sent to the server. The server always behaves exactly like in vanilla. Nothing is exploited, everything runs only on your own client – the game just feels better.


✨ Features

🔮 Crystal Optimization

  • Instant Place – Crystals you place appear on your screen instantly, instead of waiting for the server's response. (If the server doesn't accept the crystal after all, it disappears again automatically.)
  • Instant Break – Crystals you break disappear instantly, instead of lingering for a moment. If the hit doesn't go through, the crystal reappears automatically.
  • Distance Culling – Hides distant crystals so you get more FPS in big fights (optional).
  • Static Crystals – Displays crystals still, without spinning and bobbing, for a cleaner view (optional).

⚓ Anchor Optimization

  • Instant Replace – Respawn anchors react instantly instead of stuttering briefly. A background timeout makes sure everything always stays correct.

⚡ Performance

  • Reduce Particles – Fewer particles for more FPS, with a freely adjustable amount.
  • Disable Explosion Particles – For maximum FPS during heavy crystal spam.
  • Limit Total Particles – Sets a fixed cap on the maximum number of particles.
  • Memory Cleanup – Automatically cleans up in the background (optional).

⚙️ Configuration

All features can be toggled individually via ModMenu + Cloth Config. A global switch disables the entire mod when needed.

💡 Tip: Everything can be turned off or fine-tuned in the ModMenu – set it up exactly how you like. If you want the perfect settings, check out the images in the gallery here on Modrinth and just copy them.

Server operators can disable the mod for their players via the crystaloptimizersync:disable channel (server-side opt-out, complies with Modrinth Content Rules 3.2).


📦 Requirements
