I am currently running FFXIV on a very high end new PC that has no trouble with the game at all on max settings. The problem is the UI in pretty much every point, is so slow. Take for example using the Retainers. Trading items to and from it to store them takes an age, you are talking like 5-10 seconds per click. In this age of technology, we shouldn't be using something that is that slow.

Also the time between hitting a macro or spell on the action bars feels like I am playing on a wireless connection, please try to do something to improve these basic functions.
