Bura

Version: Alpha 0.2.0
Minecraft: 1.21.11
Loader: Fabric

Notice:

Bura Beta is currently planned to release in mid August. Thank you to everyone for your support and feedback throughout development!

Bura is an experimental performance mod focused on improving FPS consistency and reducing rendering-related CPU spikes. It currently targets chunk scheduling, upload pacing, and visibility work, with a strong focus on lower-end and CPU-limited systems.

Performance Snapshot

Tested on Intel Core i3-10100F @ 3.60GHz against Vanilla Fabric under the same settings and world conditions.

What Bura Optimizes

Chunk compilation scheduling

Bura reduces frame spikes caused by chunk rebuild bursts by spreading expensive work more intelligently.

Chunk upload pacing

GPU upload work is distributed across frames to avoid sudden stutter from large render updates.

Visibility culling

Bura reduces unnecessary rendering work by avoiding repeated processing for geometry that is not visible.

Compatibility

Bura is designed to work alongside other optimization mods and focuses primarily on frame pacing and workload scheduling.

Tested combinations:

• Sodium
• Iris
• ImmediatelyFast
• Entity Culling
• Lithium
• FerriteCore

Known Limitations

• Aggressive culling may still cause occasional chunk flicker or ghosting.
• Alpha build: behavior may change between versions.
• Some particle or rendering mods may require compatibility fixes.

Roadmap

• Reduce memory usage and heap allocation rate to lower gc stutter
• Improve chunk loading behavior at high movement speeds
• Reduce flicker from aggressive visibility culling
• Expand compatibility with more rendering mods
