I am currently playing at a res of 5760x1200 using eyefinity on a 5870. Currently the startfield only appears on the left side of the viewing area (about 3/8th's) Scrolling to the left will slowly move the stars to the right, but as soon as i zoom in or out the starfield resets to te same 3/8th on the left viewing around. This is made less annoying when the starfield is turned down to minimum, or zooming out

.
Sorry about the crapyness of the picture, but in full-size it would be rather big. But it gets the point across
