Description
ScalableLux
A Fabric mod based on Starlight that improves the performance of light updates in Minecraft.
Why does this fork exist?
- Starlight is no longer maintained as a mod since Mar 8, 2024.
- The performance of vanilla lighting engine is still a bottleneck for high-performance chunk generation.
- The base Starlight is still 100% faster than vanilla, allowing the chunk system to scale beyond 24 threads.
- Starlight's "stateless" design allows for parallel light updates, further widening the performance gap. It is still rather important for dedicated servers with more players to stress chunk generation. Therefore, it is still important for Fabric or other modded servers with plenty of players.
What does this fork do?
- Contains all the performance improvements from Starlight with additional bug fixes.
- Optionally allows for parallel light updates, bringing significant performance improvement in high-speed world generation and heavy light updates scenarios.
