I've managed to get onto Hyperion now, thanks for tolerating my complaining!

As a side note, the new PS4 beta (which is likely to be identical to the retail game released next week) is a significant improvement over the first beta. Most noticeable is the ability to run the game in either 'HD' or 'Full HD' mode (presumably 720 or 1080), and the ability to change the GUI size - the default being 140%. The latter is really appreciated, as you needed binoculars to read the text at 1080p on a living room TV on the original beta.
