[Suggestion] UI resolution separated from Game resolution

[wiregrind]

My suggestion is that the game should let the player set the game UI to their monitor's native resolution and have an option to run the 3D graphics at a much lower resolution for better performance.
I'm asking for this because even though my computer meets the minimal specs for the game, it only runs smooth (60fps) when I use low resolutions. Also, in certain situations, crowded cities, FATE events, or complex boss fights, the UI text gets really cluttered.

This is something that's already implemented in the PS3 version of FFXIV, the 3D graphics are running at a lower resolution than the UI. This is also implemented in most console games and some PC ports.
