About
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
-Dlomka.java22_25.optimizations: Enables experimental optimizations specifically for Java versions 22 to 25. (default: false)-Dlomka.compat.sodium.allowChunkMixins: Enables chunk mixins even with Sodium/C2ME loaded. (default: false)-Dlomka.compat.sodium.allowChunkMixins.unsafe: Enables experimental chunk mixins (needs to have enabled-Dlomka.compat.sodium.allowChunkMixins). Effective sometimes. (default: false)-Dlomka.textures.maxDimension: Limits the maximum width/height of textures. (default: 0)-Dlomka.textures.decode.offThread: Enables moves texture decoding to background threads to prevent main thread stutters. (default: true)-Dlomka.textures.decode.parallelism: Configures the number of concurrent threads used for texture decoding. (default: 2)-Dlomka.textures.decode.executor: Sets the thread pool type ( virtual , common , fixed , or platform ) for decoding. (default: virtual)-Dlomka.entities.cullInvisible: Enables entity culling of all invisible entities. Effective sometimes. (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.).
⚠️ May be useless/with conflicts
- C2ME
- Entity Culling (uses friendly culling, can be unused)
❌ Known incompatibilities
- VulkanMod (for now not considered for future compatibility)
