Notable features are: Async & Optimized Pathfinding, Eigencraft Redstone (1.16), Async Advancements, Optimizer Pathfinder, Ability to slow down villager brains, Ability to disable collisions & collisionboxes, Major Hopper Performance Improvements, Nether TNT Bug + A lot more that all contribute towards ultimate performance.

Experience Greatness

Available at the following options:

• GitHub Actions - 1.16.1

Config Entries

disableEntityStuckChecks

Default: false Entities don't check if they are stuck in a wall and should suffocate. E.g useful in hubs where player damage is canceled anyway.

disablePlayerOutOfWorldBorderCheck

Default: false Players don't check if they are outside of the world border (to take damage). Can be used everywhere where the world border doesn't apply anyway like hubs/minigames.

disableEntityCollisions

Default: false All entities stop pushing each other. The only exception is that players still will be pushed since this is clientside and controlled by a scoreboard team flag. This also breaks the entity cramming (which players can bypass anyway with ladders). Greatly improves performance where entity pushing is not required.

disableEntityCollisionboxes

Default: false Removes the collision box from entities. This only really affects shulker mobs (not shulker boxes) so that mobs will fall through them like any other mob. Players still can walk over them since that is clientside. Greatly improves performance, with minimal impact on in-game behavior.

onlyPlayerCollisions

Default: false Does the same as disableEntityCollisions except that players are still able to push other entities.

pistonPushLimit

Default: 12 Just a fun option that enables you to modify the maximum amount of blocks that a piston can push. Together with slime/honey blocks and pushable tiles from Tuinity this allows a lot of new machines/doors.

itemStuckSleepTicks

Default: 1 Controls how often a dropped item checks rather it's stuck inside a block (their most expansive operation). Higher values like 15 can be safely used and greatly improves dropped item performance if your server has thousands of them (from big farms/TNT/farming players etc).

villager.simplerVillagerBehavior

Default: false Replaces the entire villager AI to the old AI system that all other mobs use. This breaks iron farms/villager breeders/villages (WIP to fix these problems), all villagers get a random profession (if they didn't have one) like in 1.8, don't need nor use workstations and refresh their trades after some time (trades are completely unaffected). This makes villagers as performant as all the other mobs by getting rid of their "brain" (Mojang's name^^) and behavior controller system, instead using the normal goal selector system. This way villagers are over twice as performant, but with the drawbacks that for now Iron farms/villager breeders are broken, so they can just be used for trading systems.

villager.villagersHideAtNight

Default: false Addon for villager.simplerVillagerBehavior, gives villagers the ability to drink an invisibility potion like wandering traders at night to make it less likely for them to be killed since (for now) they don't stay at the village/use their houses at night and no ability for them to respawn.
