Parent: "An untrusted client would not receive the enemy position until the enemy is visible. This, however, comes with the drawback that the server needs to do the culling - That's why pretty much nobody does it right now."

You: "But... it is done with a z-buffer. If an opponent is obscured behind a nearby pillar or something, that's not going to be culled in software - that's done by the hardware z-buffer as part of the render process."

Then I explained why this doesn't make sense on the server as a generalization and isn't necessary from a technical angle.

Then you ignored that you were both snarky and wrong, provided your own source which directly contradicts what you originally said and ultimatly called yourself a victim of aggression when I pointed this out.
