About this project

What does JLava add?

JLava Mod — a hardcore core-level optimization mod that maximizes performance by utilizing 22+ CPU cores/threads.

⚠️ Incompatibilities (Breaks):

  • VulkanMod (Both mods rewrite the rendering engine, combining them will cause an immediate crash).
  • GeckoLib (Conflicts with our custom LevelLightTweak engine, causing light glitches or crashes).

✅ Requirements (Depends):

  • Sodium (JLava is built to run strictly alongside Sodium for the best FPS)
  • ✅ Really optimization
  • Fps+
  • ⚠️ Problem with package
  • Netty error connection java.socket
