## FPS, Frametime & Benchmarking<\/p>\n
**Performance Overlay** is a lightweight, client-side mod that shows **what actually matters for smooth gameplay** \u2014 not just average FPS.<\/p>\n
It focuses on **1% \/ 0.1% lows, frametime stability, stutters, and frame spikes**, helping you understand *why* Minecraft feels smooth or laggy.<\/p>\n
