If serious lag Go into Options Menu (Esc by default or main menu) and go into SnooperSettings. Then where it says "Allow Snooper: On" you want to click the button and turn it off. If you run a Minecraft Server then turning it off in server.properties can also reduce lag for the SERVER and PLAYERS a lot! Also turn off clouds and fancy graphics!!! You can also turn off packets which is more complex if you need that info tell me. Also change your fps to the highest Still Have Lag? Go through the storage on your computer and delete all uneeded apps, videos, and pictures. If there is still lag restart your computer empty your trash and turn off any start up apps. Remove Cache and delete cookies. Have a nice day- death_thrive
So is this for the server owners to do for the server or for regular players to do if their game is running slow. If you could explain your methods it would be really helpful
