Almost necessary on large servers and in exploration packs
Reputation ranks
Ranks only ever go up; points can drop but your rank stays.
About reputation ranksConcurrent chunk management engine goes above and beyond on improving the performance of chunk generation. Not only does it multuthrrad, but it also adds significant optimisations as well.
When playing on servers, a common bottleneck, especially in the early game, is for players to explore jn opposite directions and cause the server to struggle to keep up generating chunks. Because c2me allows chunks to be generated on separate threads it helps alleviate the stress from the main thread while also improving generation speed.
C2me has great support for the vast majority of world generation needs, only having minor inconsistencies due to vanilla's slight dependency on the order chunks are generated in.
I would recommend this mod for every pack.
