Bura

# Bura Version: Alpha 0.2.0 Minecraft: 1.21.11 Loader: Fabric ### Notice: Bura Beta is currently planned to release in mid september. 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.  | Metric | Vanilla Fabric | Bura Alpha 0.2.0 | Change | |---|---:|---:|---:| | Peak FPS | 140 | 297 | +112% | | Average Frame Time | 7 ms | 4 ms | -42% | | CPU Usage (Process) | 51.6% | 25.4% | -50% | | 95th Percentile MSPT | 2.96 ms | 2.28 ms | -23% | ## 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
