Lomka

Lomka is a client-side optimization mod for Minecraft. Unlike many other optimization mods that focus solely on rendering or game logic, Lomka improves the game experience by optimizing various subsystems including texture caching, frustum culling, network protocols, NBT processing, chunks optimizations and shader rendering-all without compromising visual quality.

Options

Lomka uses JSON config only: config/lomka.json (created on first launch).

• java22Optimizations : Enables experimental optimizations for Java 22+. (default: false)
• compat.sodium.allowChunkMixins : Enables chunk mixins even with Sodium/C2ME loaded. (default: false)
• compat.sodium.allowChunkMixinsUnsafe : Enables experimental chunk mixins (needs compat.sodium.allowChunkMixins). (default: false and hidden from ModMenu config)
• entities.cullInvisible : Enables entity culling of all invisible entities. (default: false)

✅ Compatibility

Lomka is designed to be highly compatible with the Fabric ecosystem. It works alongside most other mods and optimization tools (Sodium, Lithium, etc.).

Lomka works better with quick pack, ModernFix and Helium (Helium only v1.3.1 or v1.3.3)

⚠️ May be useless/with conflicts

• C2ME
• Entity Culling (uses friendly culling, can be unused)

❌ Known incompatibilities

• VulkanMod (for now not considered for future compatibility)
