Smart FPS Boost

Only kicks in when your FPS drops - finds the cause (items, mobs, particles, frames) and fixes just that, then puts it all back.

Smart FPS Boost

Other FPS mods make your game uglier all the time. Smart FPS Boost only steps in when your FPS actually drops - and only fixes what is causing it.

How it works

  1. Your FPS drops below your target (default 45) for a few seconds.
  2. Smart FPS Boost looks around you and finds the cause.
  3. It fixes only that:
    • Huge dropped item pile - hides far and extra items and XP orbs
    • Mob farm - hides far mobs (32+ blocks)
    • Wall of item frames / armor stands - hides the far ones
    • Particle storm (TNT, farms, modded effects) - drops far and extra particles
    • Nothing obvious - lowers render distance by 2 for a while
  4. When FPS is good again for 30 seconds, it puts everything back, one fix at a time.

You keep full graphics when you don't need the help, and get the frames back when you do.

Good to know

  • Client-side - works on any server, single player and Realms.
  • Works together with Sodium, Lithium and Entity Culling.
  • Hidden things are only not drawn - you can still pick up items and mobs still work.
  • Named or glowing entities are never hidden.
  • Your render distance is always given back - even if you quit while it is lowered.
