# XMLagFix — Consistent 60 FPS & Anti-Stutter Engine

**XMLagFix** is an ultra-lightweight, hardware-accelerated performance mod engineered by **Mayank Mandrai** for Minecraft 1.21.1. It eliminates micro-stutters, stabilizes frame pacing, dynamically cleans garbage collection memory spikes, and maintains rock-solid FPS even on low-end PCs and Intel HD graphics laptops.

### Core Performance Features

– **Adaptive Frame Pacing Engine**: Synchronizes frame delivery intervals with GLFW display refresh loops to eliminate sudden jitter and screen tearing without introducing mouse latency.
– **Turbo Memory Cleaner**: Automatically detects JVM heap accumulation and executes safe generational memory compaction in background threads, eliminating freezing during chunk loading.
– **Smart Occlusion Culling Optimizer**: Skips rendering non-visible block faces and dormant entity animations to drastically reduce CPU draw calls and GPU vertex overload.
– **Dynamic Background Throttling**: When Minecraft loses window focus or is minimized, XMLagFix drops framerate to conserve power and heat, ramping back to maximum immediately upon focus.
– **In-Game Performance HUD**: Toggle real-time FPS stability, memory usage, and frame pacing diagnostics with clean in-game visual meters.
