Without it, devices running on ipv6 (mobile devices) cannot connect to devices running ipv4 (Desktops and laptops) as well as sometimes the NAT pass-though just fails for no reason, because of firewalls or whatever stopping the signalling server from successfully establishing a connection between the players, what the TURN server does is serve as a relay whenever the multiplayer plugin is unable to establish a connection between players directly they instead connect to the relay server and send data through it solving all the issues mentioned above. IT's not related to using the official signalling or not.

Keep in mind that it probably has less than 30 fps but the construct engine has a "min fps" action that slows down dt if games go below 30 fps by default to allow the game to run relatively smoothly but in slow motion instead

No. Construct 3's multiplayer plugin is really really really good and has tons of features.

The problem with that is that for most users there'S too many features, it's like re-learning the engine completely. When you work with the construct 3 multiplayer plugin, conditions and actions work differently. For example the "sprite on created" condition means that you connected to a host and the action you put under that condition has the player's multiplayer plugin ID which isn't written anywhere but that's just how it works and it'S weird to the uninitiated. Also you need to setup a TURN server and that costs money and tons of effort and knowledge in linux and googlecloud or amazon web services. With photon you just get something that works boop just like that and is free but with limited features and is more appropriate to beginners

Construct3 multiplayer games need a TURN server to work properly

What I mean is, I made a really cool spritefont but I only know latin characters, so if a person who dosen't use the latin alphabet like russian or korean, no characters will show up when they try to enter a name for their character and that kinda sucks you know ?

with like not just latin characters
