Scaleable Interface

[bartekPL]

im playing on 1280x720 and i have 60 fps but on 4:3 it's easier to focus. And i have on mind this: add an option in the settings "UI size", and this will looks like scalling a speedometer or minimap.

It's impossible to do this. Static GUI elements like menus etc work in totally different way using totally different engine (CEGUI) than dynamic UI elements like speedometers (DX).
For example, CEGUI doesn't allow to scale font like DX does.
