Well, someone should start this discussion.
200 players is too much!
It is too much for mosts PC.
I have GT755, i5 core and 6GB RAM(middle PC), directX 7 ON, environment effects OFF and all possibles settings to MIN level, but after 100 players on server i have FPS drop to 30-40, so i can`t make chambers or fast blocks, or feint.
It is too much for server.
After some numbers of players above 100 server starts lagging. For example u can make block but enemy strike hit through it, or u make strike right on enemy but its not make any damage to him. Or about barrels: more people above 100 on server - less chance to get food from it.
Or another annoy thing: siege weapons like catapults or trebuchets. In the same map with less players u need for example 2/3 shells of trebuchet for destroying wall and all of them hit it, but when server has more people, u need about 4/3 shells(so u need destroy treb and wait for spawning new after it go empty) for this, because half of shells go through the wall and hit ground. In fisrt case u need 5 minutes for it, in second 5+2(spawn)+2=9-10 minutes where round time is 12, so u brake wall and round end.
All this indicates that the server does not have time to process all that it should.
Some people like dogfight with swing theirs weapons in random direction and they don care about lags, but another want skilled fights with good control of their weapons and this cant be done here.
