It Shall not Tick Mod (1.19.2, 1.18.2) is a performance-enhancing mod that restricts entity ticking to a specified range of players. The entity will tick normally if it falls within the player’s range. However, if it is outside of the range, the entity won’t tick and the client will not render it. This allows the server to stop ticking entities the player is not interacting with. FTB Chunks is also integrated by the mod, allowing entities in claimed chunks continue ticking as usual.
