It should load in as you are creating your character (switching through options), if you have a character just load into the game.
See if the graphics setting need reselecting, best way to save them is: Apply them, logout to character screen then exit game from there.
If it still doesn't work do: Try deleting your shaders cache folder (while the game is open) and restart the game. The cache is located at \Documents\ArcheAge\USER\shaders\cache
