TPSShower

A Fabric Client-Side mod that will tell you what is lagging in your game. It can estimate the server's TPS, and tell you if your client is lagging.

Uses

This mod can tell you if the client or the server is lagging, or if the world is making you lag. Because it is Client-Only mod, you can use it on client while being on a Paper/Bukkit/Spigot/Vanilla/Forge/Fabric server.

GUI

You can press (by default, change in minecraft controls) F7 to enable/disable the overlay. The overlay is like the F3 menu, without text backgrounds. It contains 3 categories:

• CLIENT: Tells you some useful information about client-lagging, such as FPS and Ping.
• WORLD: Shows you if the world makes you lag, by displaying entities and block entities count, and rendered chunks. If you see that your world makes you lag, maybe reduce your render distance.
• SERVER: Shows you an estimation of the server TPS. Can be useful if you see some lag, and you want to check if the server is lagging or your client. Can be useful too if you're a server admin, to see if your server is lagging without commands. (WARNING: TPS is an estimation. It uses the WorldTimeUpdateS2CPacket to check the server TPS. Keep in mind that it can take some times to do a good estimation, especially when the server TPS is lower.
