I have been playing on a Noob friendly server where the focus is to just get used to playing the game. The raiding and attacking others is not a priority and even if a raid does occur, they established rules to not kill your pets and not destroy your whole base. They also have 5x taming, 4x XP and 4x gathering. If you are interested in joining me on it, the name is "Noob Friendly PVPVE, 5X taming" etc. etc. They have a TeamSpeak server at ark.disruptiondigital.com .
If you are more interested in raids and such, this is not the server to play on.
By the way, when joining ARK it gives several graphics options including "4gb" I'm not sure the rest of that option name, but it runs very smoothly for me on my limited GTX550TI.
Let's play!!
