With the Xenon Graphics Engine, saving does not have to go to disk; text remains text; vectors remain vectors; and images stay as they are without being baked into RGB. In the past, for example, image previews would be cached somewhere on the hard disk, and the time to create image previews would vary depending on the type and size of the image, and the computer used. Quark 10 no longer uses image previews. The graphics engine just draws the image directly on screen using the latest processor technologies.
