Nolith
by lazydev418
Nolith is a Forge optimization and utility mod for 1.20.1 that adjusts entity tracking, inventory triggers, predicate matching and resource pack caching.
What it does
Built as a privately used server tool and continuously updated over time, Nolith gathers targeted performance fixes and optional gameplay settings in one Forge mod. Dynamic entity tracking changes how far entities are tracked based on server load and player ping, which lowers network traffic. Inventory trigger cooldowns space out advancement checks that would otherwise fire on rapid inventory changes, and matching of item conditions tied to enchantments, stored data and potion effects is made faster.
The client side keeps server resource packs in a cache, so a pack already received is not fetched again. Server administrators can relax or adjust the vanilla limits on player movement and vehicle speed, and shield blocking delay can be set. Every option is configurable, and the mod is maintained with new fixes and optimizations as the project grows.
Nolith is released under the MIT License and is not open source. It is published for Forge only, with the latest file 1.0.9 for 1.20.1 from 2026-08-09. Every player and the server need a copy of the mod.
Key features
Dynamic entity tracking
Tracking range for entities scales with server conditions and player ping to reduce network load.
Inventory trigger cooldowns
A 10-tick cooldown on inventory change triggers reduces lag caused by rapid inventory updates.
Optimized predicates
Matching of item conditions tied to enchantments, stored data and potion effects runs with less processing.
Resource pack caching
Server resource packs are cached on the client, so a pack already received is not requested again.
Configurable movement limits
Server administrators can bypass or adjust vanilla limits on player and vehicle speed, reducing players being moved or desynced wrongly.
Passive shield mechanics
Passive damage absorption shields come in heavy, standard and small categories, with a configurable shield block delay.
Customizable HUD
Client-side settings hide selected interface overlays, including the health display, armor display, experience level, crosshair and boss bars.
