Without going into too much detail, the performance will be similar to Singleplayer.If the person hosting the game can handle 500 blocks in singleplayer, then the multiplayer game will also handle 500 blocks, total, as well. If they can handle 1000, then the multiplayer game will run 1000, it’s as simple as that! The amount of blocks you are able to support is proportional to how powerful your computer’s processor is.

All processing for the game’s physics is done on the host’s computer, which means everyone else can play the game even if they have a low spec computer!
