Actually, graphic changes will do nothing for server and latency problems. Even the lowest single pixel textures and block-ey models wont get over the fact that the server is trying to keep track of 1000 people using hundreds of diffirent actions, movements and stuffs in one single zone, on one single monster, in one single spot.

It will increase your own computer's performance in the way of running smoother, however that has little to do with the troubles the server has.

For those of us with monster computers who can run this game with ease, it stutters too, only due to the number of connections all trying to interact with the same object and each other, since the server sends the data from everyone to everyone as well for positioning and triggering of animations. They had a decent half-fix by giving monsters priority and only letting you see a certain number of people, which meant the amount of back/forth communication was minimal between players.

However, nothing short of blatantly doubling or tripling their server power will fix the problems. However cost/reward for one single battle is... yeah... :/
