I don't have any screenshots of the previous graphics to compare with, but things seem to be more detailed than it should be on lowest graphics e.g. stars in the night sky, extra particles on items such as Ixion's horn that do not appear on the lowest quality. When changing graphics to the highest possible setting, these features remain the same. However when manually switching to the lowest possible settings in game, the some of the settings do not appear to change from the high quality settings.
