What's new

First public beta.

  • Server-side optimizations for JujutsuCraft 50.x: direct execution of internal commands, grouped particle packets, cached lookups, fewer repeated block reads in domain and destruction procedures.
  • Measured: -28% server time per tick on moves cast by mobs, -14% on moves cast by a player, about half as many lag spikes over 50 ms. No gameplay change.
  • /jjfix optimizations [on|off|config] (operators) to compare live without restarting.
  • Fix: Black Rope, Mahito's hand and Playful Cloud no longer prevent a dedicated server from shutting down.
  • Does not improve FPS. Required on both client and server.
