Jerky movement on other clients than the host

Hello, let's say that player 1 is the host, and player 2 is just a player that joined the game.

On the screen of player 1, the movement of the player 2 looks very smooth.
But, on the screen of player 2, the movement of player 1 looks very jerky and bad, while there is a function to smooth the position of each player.

Does anyone know why this happens?

One more question, I don't know what happened, but now I can't create a local server with the Unity running and then have another window(.exe) join the server...
But if I host the server with the .exe, the one playing with the unity program can join, why?:S
The same happens if I use 2 .exe clients

Thanks for your time

 

Well, the second one sounds like you might have turned on latency testing, which might also cause your first problem.

 

Regarding the "snapping" that you see, do you use Network Transform or do you sync position yourself?
From my experience, Network Transform works very poorly and doesn't really interpolate between states - I would recommend implementing it yourself (this is what we did, and works very well).

Regarding the 2nd issue, I didn't quite get the problem - but I think you're trying to open 2 servers on the same machine, which Unity doesn't like since the port is already used up
