Description

Works with OptimizationsAndTweaks.

Some tweaks are configurable and I recommend reading the config file to learn more about them.

Non-configurable changes:

  • New worlds use the modern naming scheme "New World (n)" rather than continuously appending dashes
  • Backport of the Phosphor lighting engine (fixes many lighting issues in vanilla)
  • Better LongHashMap implementation (together these two changes fix the infamous 1.7 stuttering)
  • Optional 1.8-style occlusion culling (improves FPS, disabled by default)
  • Hacks to prevent CME crashes during world generation
  • MC-30845
  • MC-2025 (partially fixed, full fix is in progress)
  • Villagers no longer lock all their trades
  • ChickenChunks should no longer crash in combination with chunkloading from other mods like Extra Utilities
  • Various memory leak fixes (most noticeable when changing dimensions or exiting/rejoining the world)
  • Matter Overdrive only recomputes its registry file if one does not already exist in config/MatterOverdrive
