what you ned to decide is:
1. how much of this can be pre-processed. If you are displaying a fixed image/text you can do it in an image editor and just display that
2. can you divide the screen into "change zones", where you grab and change only the sections that actually change.
full screen grabs are slow no matter how you cut it. your job as a programmer is to figure out a faster approach to get the desired result.
one idea is to use a "background" image tat never changes and a foreground image that moves. I'll knock up something later
