AAC (Advanced Anti Cheat) (Hack & Kill aura Blocker)
AAC is fast. AAC has phenomenal performance. On this server with 140-150 players, AAC uses less than 4% of the tick, and less than 2ms in total, equivalent to less than 0.03%/tick per player. AAC is asynchronous by design, performing the majority of its work at the packet level rather than on the main server thread.
