Basically all you need to do is get in game and go to options and go to Quality - the top bar needs to be set to something other than user.
The method that worked best for me was to log out all the way. go to Documents > Archeage > delete all the files at the bottom of that folder (don't go deleting the folders just the files that show up under the folders). Go to LogBackups under the Documents > Archeage folder and delete the Archeage Folder inside the LogBackups folder.
Restart the game and press Alt + Enter once at server select to get out of full screen mode. Select Server and get in game with a character. Set your resolution that you want and go to Quality in the options. The main bar at the top of the quality settings should be set to "user" prob. Set this to what ever else you want, i used Medium since i have a potato gpu. I turned all of my shadows off (NOT messing with the sliders) I also turned off the HDR effects and Water effects, Apply changes and X out at the top right corner of your screen. Once back on the desktop you should be good to go. Just dont' mess with your settings anymore.
