Is a problem or not?

Hello! Today I installed ArmA 2 and Operation Arrowhead expansion, then I downloaded torrent files etc. .. When I start the mod Combine Operations, appeared to me a black screen with the codes that I can not copy because they are only for 1 second then disappear. Just disappear, not the part I play, but after searching on the internet, I saw that to run the Combine Operation, Steam needed to start with the administrator. Now it works, but the problem is not that. Actually what I want to tell you should not be a problem Dayz, however, now I will explain. Just before, all normal, I try a server, before, after 10 minutes, and just respowno the map when I turn around there's a lag crazy. But not those who will carry forward lag of 20 meters and then you return back, but a subspecies of the lag to explain that one could say that it is SLOW to do everything. I turn right and there's that fluidity in the game, such as Call of Duty. It 's much different. ALL 'S SLOW. I do not know how. Now I'm trying to install the game on another PC to see if it changes, because I use a laptop: http://www.notebookcheck.net/Review-Asus-X53E-SX082V-Notebook.57227.0.html (IntelCore i7 video card GeForce GT 520MX 1GB, 8GB RAM). I do not think is a problem on your PC, watch it. Why I still Call of Duty 4 and Call of Duty 2 (sorry spam), your computer, and there is no type of lag or slowdown. I do not think even my connection, because she never lagged, and neither is a problem of the server where I went, because he had 80 ping. And I have tried as many as 3!

Thanks!
