invisable players?

[Gothicshark]

I have been seeing this a lot. Random monster in the overworld getting killed by an invisable player. Sometimes it is a group of invisable players aoeing down monsters. I will then see a trio of gibberish named players all following one guy around. The group is only visable in a town or quest hub and vanish outside town. This seems most odd to me.

2 possibilities, Bots as mentioned above, or full server with too many players close by. If your graffics card isn't set to max it will fail to render players if there are too many, and even with a max setting like my system, some people will fail to render or pop in and out of visibility in crowded areas ie Ul'dah at peek times on Balmung. or Fate trains during the Yokai event.
