Node Pulse Monitor Mod FAQ
10 questions players actually ask, answered.
How do I open the Node Pulse Monitor?
Press the default keybind (usually a configurable key) to open the monitor overlay. You can customize this keybind in your mod settings to use whatever key you prefer.
What's the difference between CPU and GPU usage in the mod list?
CPU usage shows how much processing power each mod consumes during game logic and ticks, while GPU usage shows rendering load. A mod high in CPU but low in GPU (or vice versa) helps you identify whether it's a logic or rendering problem.
Why does my startup time graph show huge spikes?
Large spikes during startup usually mean a mod is loading heavy assets, generating data, or performing initialization tasks. Check which mod corresponds to that spike in the startup times list to identify the culprit.
How do I use the Lag Map to find problem chunks?
Open the Lag Map tab and look for colored regions indicating high entity or tile entity density. Travel to those chunks in your world to see what block entities or mobs are causing the slowdown.
What does the flame graph actually show me?
The flame graph displays a visual stack trace showing which functions are consuming the most time, with wider blocks meaning longer execution. This helps you pinpoint the exact line of code or process causing a bottleneck.
Can I monitor performance while the monitor is closed?
Yes, the mod continues collecting data in the background even when the overlay is hidden. Open it anytime to view the recorded performance history and graphs.
Why does the memory graph keep climbing even when I'm not doing anything?
Memory naturally accumulates as the game runs; this is normal. If it climbs extremely fast or never drops, you may have a memory leak in one of your mods—check the memory tab to see which mod's heap allocation is growing.
How do I know if a mod is causing frame drops or just tick lag?
Check the frame time graph versus the CPU usage graph; if frame times spike when a specific mod's CPU usage is high, that mod is causing frame drops. If tick times are high but frames stay smooth, it's server-side lag.
Does this mod work on multiplayer servers?
The mod monitors your client-side performance (your computer's CPU, GPU, and memory). Server-side performance requires the mod to be installed on the server to track tick times and server load.
What should I do if the monitor itself is causing lag?
Close the overlay when you're not actively monitoring, as rendering the graphs uses resources. You can also reduce the graph resolution or sampling rate in the mod's settings to lighten its footprint.
