Zombies/players warping/going invisible, lag

[Sneaky (DayZ) 0]

I just started playing dayz a few days ago and me and my friend have some issues with lag:

* Zombies sometimes run away from me, then go invisible and all of a sudden they're in front of me

* Zombies lag out and even though they are far away from you they hit you

* Zombies sometimes stop and start punching even though they're not near me (as if they were punching me)

I see others player lagging, like they would walk or run into one direction and then all of a sudden they're somewhere else, or run backwards into walls and stuff.

Is this normal because the mod is still in alpha or has this something to do with my pc or connection? I'm not the only one getting this, so does my friend.

Depends on what server you're playing on?

Well we tried lots of different servers but it's all the same everywhere.

Consider that it may be an issue with you? Firewall blocking? Something causing you to lag severely?

I have nothing running but steam, teamspeak and arma2 of course. There is nothing on my PC which could make me lag like this, I don't have a router and my firewall is accepting arma2, so I don't know.

Change settings? I know Shadows and V-Sync give me lag.

Uhm no. I'm running everything on low already :/ Is there really no one who has this issue?

All right, just a little update. We started trying USA servers and we're finding random USA server which have none of these issues at all, while EU is mostly laggy. These issues are definitely server sided, I'm guessing some hosts are overloading their servers or something.
