What is this?
Observable profiles (tile) entities and shows you what's taking up tick time and where. It's available for Minecraft 1.16 - 1.21 on (Neo)Forge and Fabric. Get it on CurseForge, Modrinth, or GitHub.
How do I use it?
First, make sure you have permissions to run it. By default, only server operators can use the tool. They can allow everyone to use the tool by running:
/observable set allPlayersAllowed trueto allow everyone, or/observable allow <username>to allow a specific user.
Once that's taken care of, bind the "Show profiler screen" key to whatever you prefer, or
run /observable run <duration>
if you're an operator.
I'm still confused!
I have an incomplete wiki available here or you can talk to me on Discord.
