No lag in ArmA2 & Intense lag in DayZ

[No lag in ArmA2 & Intense lag in DayZ]

My graphic settings don't change a single thing about my FPS in DayZ.

It did help a little, it doesn't freeze anymore and my fps went from 13 to 16. Thanks.

I'd like to have a solution for this low FPS, because I do not have a low FPS in ArmA2 and it's very annoying.

I'd like to have a solution to this. I just bought the game and I'd like to be able to play it.

I can move around, even though it is painful to have this ''freeze'' every 5-10 seconds. It is currently impossible to shoot a gun for me because of this terrible framerate and constant freezing.

I am wondering what causes my computer to lag this bad while playing DayZ. I can run ArmA 2 very smoothly but DayZ is a whole different story.

I've noticed that other players had this problem as well but I did not find any solution to it. I searched the forums but couldn't get an answer but if there is already a thread for this problem please direct me to it.
