Supplementary HUD

Supplementary HUD

Supplementary HUD is a lightweight, fully client-side Fabric mod that adds a real-time performance overlay to your Minecraft screen. Monitor your FPS, network ping, TPS, and MSPT without requiring any server-side mods or plugins.

Features

• 100% Client-Side — Works on singleplayer, vanilla servers, modded servers, and Realms. No server installation or permissions required.
• FPS Monitoring — View your current client FPS in real time.
• Network Ping — Monitor your connection latency to the server.
• TPS & MSPT Monitoring — Estimates server tick performance from network packet timing, providing useful information for identifying potential server-side lag.
• Configurable HUD — Customize the overlay's position, layout, and displayed information.
• Lightweight — Designed to provide performance information without noticeably affecting gameplay.

How It Works

Supplementary HUD observes incoming network traffic on the client and uses packet timing to estimate server tick intervals. These measurements are used to display estimated TPS and MSPT values alongside your FPS and network latency.

Because these values are calculated entirely on the client, Supplementary HUD does not require any modifications to the server and does not alter gameplay or send additional monitoring data to the server.

Note: TPS and MSPT values are client-side estimates based on network timing and may not exactly match the server's internal tick measurements.
