PerformanceHUD

A lightweight client-side performance HUD that shows FPS, RAM, entities, loaded chunks, ping, and CPU usage in a single clean corner overlay. No screenshots cluttered with three different mods — one toggleable panel, one hotkey, done.

Client-side only. Do NOT install on the server (and you don't need to — vanilla servers work fine).
Singleplayer note: Works perfectly in singleplayer. Just drop it into your mods folder.

What it does:

• Renders a compact HUD in the top-right corner with up to 6 live metrics.
• Toggle the entire overlay with a single keybind (F8 by default) — no menu digging mid-game.
• Per-metric on/off switches, so you only see what you actually care about.

Metrics shown:

• FPS — current frame rate with frame time in ms (e.g. 120 (8.3ms)).
• RAM — used / max heap in MB.
• Entities — entity count in the loaded world.
• Chunks — currently loaded client chunks.
• Ping — your latency in ms when available; otherwise shows -.
• CPU — system CPU load percentage when available.

Configuration:

• In-game screen: Open with /phud open or /performancehud open. On Forge/NeoForge, it is also available from the Mods menu.
• Customization: Adjust background opacity, screen margins (X/Y), and line spacing in the config screen.
• File: All settings live in a single human-editable file at config/performancehud.json.
• Keybind: The default F8 toggle can be changed in the vanilla Controls menu.

Commands:
Use /performancehud or the short alias /phud.

• /phud open — open the config screen
• /phud status — print current settings to chat
• /phud reload / /phud reset — manage the config file
• /phud <setting> <value> — instantly toggle metrics or adjust visual settings directly via chat (e.g., /phud showFps false, /phud xMargin 10, /phud textColor 16777215)

Compatibility:

• Safe alongside most other HUD, minimap, or performance mods. It draws a client-side overlay and does not modify world or server logic.
• Pure client-side. Modded and vanilla servers accept it without any handshake.
• Safe to remove at any time.

Localization:
Available in English, Russian, German, Spanish, French, Italian, Japanese, Korean, Brazilian Portuguese, and Simplified Chinese.
