Bura
Bura is an alpha Fabric performance mod that reduces lag spikes and improves FPS stability by optimizing chunk compilation, upload scheduling, and visibility culling in singleplayer.
Bura
Version: Alpha 0.1.0 | Minecraft: 1.21.11 | Loader: Fabric
Bura is an experimental performance mod focused on improving frame time consistency by optimizing core segments of Minecraft's rendering pipeline.
Performance Comparison
Tested on Intel Integrated Graphics vs. Vanilla Fabric
| Metric | Vanilla Fabric | Bura Alpha 0.1.0 | Improvement |
|---|---|---|---|
| Peak Performance | 144 FPS | 268 FPS | +86% |
| Max Frame Spike | 20ms | 7ms | 65% Reduction |
| Average Frame Time | 7ms | 4ms | 42% Reduction |
Technical Approach
Chunk Compilation Optimization
- Reduces heavy frame time spikes caused by chunk rebuild bursts.
- Applies scheduling strategies to avoid executing large rebuild workloads in a single frame.
Chunk Upload Scheduling
- Distributes GPU upload operations across multiple frames.
- Reduces sudden workload spikes caused by large batch uploads.
Visibility Culling Improvements
- Reduces unnecessary rendering work by improving internal visibility checks.
- Avoids redundant processing for geometry that is not visible to the player.
Compatibility
Bura is designed to work alongside most major Minecraft optimization mods.
It focuses on frame time stability and workload scheduling, rather than replacing existing rendering or memory optimizations.

Alpha Status and Known Limitations
Bura is currently in early Alpha development. Users should be aware of the following:
- Visual Artifacts: Some aggressive culling features may cause occasional "ghosting" or chunk flickering. These are known issues being refined for stability.
- Compatibility: Currently optimized primarily for singleplayer performance.
Planned Improvements
- Refinement of visibility culling to eliminate flickering.
- Further chunk pipeline optimizations.
- Expanded compatibility with major rendering frameworks.
