I don't know game development but uh do you? What are you rendering when the player can't see them? I might legitimately just not get what you mean

You constantly have to render people in when they can't be seen but will soon be seen. Which also means instead of keeping track of just locations the server needs to render the scene in sufficient detail as to determine sightlines.

Usually games just do this by sending info to clients of where everyone is and letting the clients render people in when the client determines that the sightline isn't interrupted.

Some games will just not send the positions until they're within a certain range of each other, but I'm a realistic game like tark you'd need several kilometers of info in case someone scoped in.

If you don't do this correctly it leads to characters popping into existence from thin air

You could use things like ray tracing to determine if one player can be seen by another on the serverside and only send packages when they can see.

But to resource heavy to do that.

Edit: Thinking about it, you simply have to render the whole map with all players server side and based on that determine which players can see each other and based on that send the information to the clients.

You do see why that's a serious issue right? Before the Server did nothing more than maintain a list of x,y,z coordinates of player positions. Now it's rendering the entire game space and doing 3d calculations.

That's several orders of magnitude more complex and costly.

That's exactly what i said.

Still no reason to put a root kit on the customers PC.

There's no way in hell you'll ever get a game company to agree to that. You're talking 100x the expense of running a server at a minimum.
