What is the point of the login screen image at all then?
It's so blurred its a complete waste of settings, images, company logos spent on it.
It looks to me to be more blurred than the half life model (will have to go check when I get home) but even compress you only know the pic is dunes because we know the original.
As far as I am concerned, have images, or no images, big blurs are a waste of time, and frankly can be procedurally generated without all the tedious mucking about with large hi res image files that look that the were scaled from an icon to full HD resolution.
