Even with the battle royale craze, it seems like nothing has really replicated Planetside 2's black magic netcode (or at least amassed a playerbase big enough to show it off).
I know Planetside 1 was pretty heavy on client side - not sure about PS2 (but my impression was that it would be less client side logic - to avoid some of the cheating.
I think some time ago (2 years or more?) there was this guy, I believe from The Netherlands, who had made a game that seemed to be to support a massive number of players with minimal hardware requirements.
I wish I could find the post, but I tried to search it in the past, without success. He did have a video with many players in game on YouTube.
Perhaps someone else remembers and can find the post.
found a small thread on reddit which posed the same questions [0]. it looks like the above comment hit it on the head; mostly client side with server just handling messages. looks like it didnt scale well either.
Yeah they've claimed that for awhile with no results. Dual Universe (which I backed) also demoed a many player test, but its never accumulated much pop and is not really a "fast" fps either.
