Smart Particle Culler is a lightweight, single-purpose performance mod designed to boost your FPS by preventing invisible particles from being created.
In vanilla Minecraft, the engine continuously instantiates, calculates physics, and renders thousands of particles (campfire smoke, furnace smoke, brewing stands, lava, spawners, torches), even when they are completely hidden behind solid walls or underground.
Smart Particle Culler intercepts particle creation at its source. If the target position is occluded by opaque blocks relative to the player's view, the particle creation is cancelled immediately.
