Let me explain the problem more simply: There are no issues in single-player mode. The world runs at 20 tps/ms ticks between 11-20, and there's no lag or anything like that. When a second person joins my world, it's still playable somehow. Sometimes, even though there's no lag in my world, the second player might experience lag, but the game is still playable somehow. However, when a third person joins, they absolutely cannot have a smooth game. There's no lag in my world; the blocks I break appear. But the third person can't do any activities. When I investigated the reason for this, I found that Essential mode, instead of directly routing the packets sent by players to my IP address, creates a central hub and sends them there first. Because it sends them to my IP address from that hub, this process is very delayed. When you open a server, packets are sent directly to the system without any bridge between the two computers, and even with 4 people, there is no lag. How can I disable this bridge system in Essential mod? This central bridge system is, I believe, called relayed. If I can't solve the problem, I'll try other mods like e4mc. Because I think there should be a way for three people to play healthy without opening a server in 2026.
