Your suggesting the server maintain a real time render for every single player and somehow manage to get the data back to them in less than 17ms so that they don’t have empty frames that suddenly become people?
Because that’s a ludicrous requirement in terms of latency (ping is totally reasonable at any value under 100ms) and server capacity.
Because your solution sounds like it would cause popping constantly and be a major burden on the server, which is already the largest overhead on a released game.
