# Lazy Chunk Load Changelog --- ## 1.1.0 — 2026-06-17 ### 🆕 New Features - **Stepped CPU Throttling**: Main chunk loading now dynamically adjusts its frequency based on CPU usage. Full speed below 85% CPU, progressively slowing down between 85%~100%. At worst, chunks are processed every 0.2s — terrain never gets stuck. - **Preloading Enabled by Default**: Background preloading is now on by default. Idle players will have surrounding chunks generated automatically. - **Priority-Based Preloading**: Chunks are prioritized by three weighted scores — distance (closer first), look direction (ahead first), and aging (long-unloaded first). Chunks under your feet and in front of you load first. - **F3 Debug Overlay**: Press F3 to see CPU usage, chunks loaded per tick, throttle status, and preload state at the bottom-left of the screen. - **Warmup Protection**: No throttling for the first 10 seconds after joining a world, ensuring spawn chunks load quickly. - **Save Safety**: Preloading and throttling are automatically paused during world saves to prevent conflicts. - **Emergency Pass-Through**: If a player steps into an unloaded chunk, all limits are bypassed — the chunk loads immediately. - **VulkanMod Compatible**: F3 overlay silenty disables itself when VulkanMod is present. Core functionality is unaffected. ### 🔧 Optimizations - CPU polling uses a 1-second cache (down from once per tick), virtually zero overhead - Preload queue periodically prunes already-loaded chunks to prevent memory bloat - Preloading auto-pauses during player movement to avoid competing for CPU ### ❌ Removed - Removed `/lazychunkload` commands to avoid server permission issues - All settings now managed via `config/lazychunkload.json` and `config/lazychunkload-runtime.json` ### 📦 Supported Platforms | Platform | Version | |---|---| | Fabric | 1.21.x | | Forge | 1.20.1 | --- ## 1.0.0 — 2026-06-14 - Initial release - Basic CPU monitoring and throttling - `/lazychunkload status` / `tips` commands
