About this Mod

This is a simple mod that shows if you are lagging or not. I looked to see if a mod like this existed and I found a few that only mesure ping but I wanted to see everything.

This tracks:

  • FPS
  • Ping
  • Ping jitter
  • CPU Load
  • JVM heap usage (minecrafts allocated memory usage)
  • Wifi Signal Strength (when possible)
  • Server TPS (an estimate)

How the tracking works:

  • 4 bars green means good signal with little to no lag
  • 3 bars amber means ok signal with little lag
  • 2 bars orange means slightly laggy
  • 1 bar dark orange means laggy
  • 1 bar red means very laggy

If it is on 1 bar laggy or very laggy it will display the main reason of it lagging next to the indicator in red (like if your ping is bad it will say ping, fps is dropping will say fps, etc)

If you want better detail in your lag while still being somewhat unobtrusive, you can turn on the realtime graph in mod menu that shows a line graph of your lag.

If you want to change what the indicator tracks (for example instead of all metrics only track one) you need mod menu.

I tested it on my Mac and it worked well but it is untested on windows so I am not sure if it works on windows or not.

Frequently Asked Questions

Does Am I Lagging? need to be installed on the Minecraft server?

No. Modrinth marks Am I Lagging? as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Am I Lagging? require?

Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.11, 1.21.10. Files for different loaders are not interchangeable.

Am I Lagging? is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
