Observable profiles (tile) entities and shows you what's taking up tick time and where. Forge and Fabric compatible. (Note: default keybind to open profiler GUI is r.)
This mod seems to work with major modpacks (Fabric packs tested more often than Forge), but I won't guarantee anything. Also please report any bugs on the GitHub repository here.
Current known issues:
- Results screen is sometimes empty (closing and reopening the GUI fixes it)
- Why is the mod crashing on startup with a "java.lang.NoClassDefFoundError: kotlin.jvm.<whatever>"?
- Does this mod need to be installed on the server?
In order to work, yes. Also, players can connect without the mod installed on the client, however they will not be able to use any of its features.
