I just started playing and when i spawned in the Crash Sight i wont stop flashing and can't shoot the bushes away.

Also when i play on my character that is in Haven i can walk across the map but after 30 seconds or so i go back where i was when i logged in.
Does any one know if this is server lag or computer lag. I am running on Windows 7 64 bit with a graphics that is powerful. [Don't remember what it is]
