I have notcied a lot of people asking the same general questions so I thought I could help.

1). Why can't I wear certain clothing?

-In ARMA 3 if you select BLUEFOR etc, you will only be able to wear those sets of clothing and gear for that faction. Select the Civilan class and you should be fine to wear anything.

2). There are no zombies...where are they?

- I had experianced this as well and I simply check my paramaters and noticed that I had my zombies set to a flat line. I simply changed them to a max of 20 in a 50m by 500m zone. The parameters can be adjusted in the faction selection screen at the top.

3). What does this "clutter, no clutter" mean?

- It is the draw distance of items. Set to low or to none in order to improve performace.

4). Cars are exploding in the distance...why?

- It is still being worked on by the developer. To reduce the performance hit, lower you number of vehicles in the parameter screen or lower the Partical effects in your graphics settings.

5). I am lagging terribly and do not know why...

- There is still a bug in ARMA 3 that forces the client (you) to use the same FPS that is running on the server (dude you are connecting to). If they have a weak rig then you will suffer no matter your specs. Also, try reducing rain and fog effects to help as well.

6). My bud is next to me yet he cannot see me....

- There is a syncing issue and I believe that the developer is aware of. If there is a bug simply post it in the feedback section. Craig is really good about getting back to you and make sure to be able to tell him what happened.

7). I am seeing error strings and a black box of doom on my screen...

- Chances are you are running the game using the DEV build. Be sure to opt out in the beta tab in the properties section of the game in your library.

HOPE I HELPED! =)
