Why do I lag in DayZ, but not in Arma II

[xRecklessRobx 2]

I don't get it. I don't lag at all in Arma 2, and can run the game on high settings. Then when I go to play DayZ, I get like 15 to 20 frames per second, when I'm NOT in a big city. I've looked at all those Youtube videos that tell you have to increase your FPS in DayZ, but none of them helped, and I still lagged. Can someone tell me why this is?

DayZ has lots of zeds and loot on the server.

Desync, Zombies, Loot, Vehicles, lots of players, bad optimization.

Well...think...There's ONE difference between the two....could it possibly be that?

Lag and FPS are different. If you're lagging, you have a bad connection displayed by high latency. If you have poor frames, it's because this mod is not optimized and requires lots of data processing, whereas Arma is a finished product.

I had luck by cranking the settings down (except resolution/3d objects). Not rendering textures from as far away has given me a great boost in frames. Unfortunately, you just have to play around with it and wait for a better performance from SA (hopefully).
