NetPulse

NetPulse is a lightweight FPS, network latency, and addon-memory monitor for World of Warcraft Retail.

It is designed to provide the performance information you actually want without turning into a full system-monitoring suite.

Features

• Live FPS monitoring
• Home latency monitoring
• World latency monitoring
• Optional total addon-memory monitoring
• Hover over AddOns memory to see the highest-memory addons currently loaded
• Horizontal and vertical layouts
• Movable and resizable as one unit
• Lock/unlock positioning
• Persistent position and per-layout size
• Color-coded FPS and network values
• Optional draggable minimap button
• Native World of Warcraft Settings panel
• No external libraries
• Lightweight timer-based updates

Addon Memory

NetPulse can optionally display the combined memory usage of your loaded addons.

When enabled, hover over the AddOns memory reading to see a breakdown of the highest-memory addons currently loaded, sorted from highest usage to lowest.

The tooltip displays the top memory users while keeping the main NetPulse display compact.

Addon-memory monitoring can be disabled completely from Settings if you only want FPS and network information.

Themes

NetPulse includes several built-in themes:

• Minimal
• Dark
• Blizzard
• Forged
• Blizzard Native

Blizzard Native is designed to blend more naturally with the modern World of Warcraft interface while still keeping NetPulse compact and readable.

Layouts

NetPulse supports both:

• Horizontal
• Vertical

With addon memory disabled, the original three-metric layout displays:

FPS | Home | World

With addon memory enabled:

FPS | Home | World | AddOns

The display can be moved, resized, and locked in place.

Performance

NetPulse is intentionally lightweight.

• FPS updates approximately every 0.5 seconds.
• Network latency updates on a slower interval appropriate for WoW's network statistics.
• Addon-memory polling only runs while the memory metric is enabled.
• The addon-memory tooltip refreshes when opened rather than continuously.
• No permanent display OnUpdate loop is used.

Compatibility

World of Warcraft Retail / Midnight

Currently updated for:

Retail 12.1.5

Development Status

NetPulse is actively maintained.

Version 0.3.0 adds optional addon-memory monitoring, a sorted memory-usage tooltip, the Blizzard Native theme, and improved dynamic layout support while preserving the original lightweight NetPulse design.
