If you are experiencing lag during multiplayer, then we recommend that the host lowers the graphical settings of the game as their computer must work more than usual. It is also highly advisable that the host should be the player with the most powerful computer among you.
We also strongly suggest that you choose the same server region as the one you are in, and ensure that you connect to high-speed, stable internet while playing the game.
The same as above applies to mobile devices as well. In order to reduce the graphics quality, please press on the gear on the top left of your screen, select “Graphics” and then “Low”. The server region can be changed from the bottom right of the starting screen.
If you’re playing on Steam, you can also use the Remote Play Together feature as a workaround.
