1. The lag is more due to the PS4 hardware and it loading in the massive map
2. Download the iZurvive app on your phone or pull it up on a pc. You can place markers with notes on the map so you can find ur base and other players. You an also set up a group that all of your friends can join where everyone on that group can see your markers and their markers too. This way its easier to meet up.
3. I haven’t had any issues when inviting friends
4. There are no clans. Use iZurvive map group to add people u want to play with
5.there is no crafting menu. Never has been and never will be. Look up crafting online for recipes.
6. See iZurvive and u can cut up a raincoat into arm bands so u will know who ur friends are in the game
7. Again see iZurvive and/or learn the map
bonus—- do your research on the day z online. There is loads of information on how to play, tips, etc
