confirm the very low loot respawn

Don't do this. Otherwise it won't be real. You don't know the name of a dead person even if he is alive you don't know it. There should be no way to get the name of a person if he or she didn't said it to you. Where the hell you get the knowledge about a persons name without knowing him? Read it from his forehead? I don't think so..

Very sorry to say this dude but with this specs you won't be able to play the game on a state where it looks good and runs smooth. It would awesom if it would run smooth while looking shitty...

The laptop to bad to run the game. Dayz is a really CPU intensive game so at least you need a gut CPU and a good graphics card.
Since your laptop only runs on a integrated onboard graphics card which is bad for gaming and also does not have a newer cpu you wont have a chance to play the game.
Laptops are not made for upgrading hardware. The only components which can be upgraded ist RAM. In your case upgrading RAM won't fix the Problem.

If you want to play the game you should buy a new PC.
For about 600$ you will get a Desktop PC without a monitor and periphery which runs DayZ fine.

This idea is really awesome. But i think this will be very hard bring it in the game without heavy bugs.
