Thanks to a lot of folks here in this thread I had a much better go of it with this game last night. I was able to shrink and move a few of the menus so they weren't cut off due to overscan. Though the chat thingy dealio in the bottom left corner is still fucked. I found no way to manipulate that window at all, so it's still cut off, though it doesn't appear to be anything vital. Still, it's much better now overall.
But I still find the map system wack, yo. If a waypoint is in another portion of the world, I have a bitch of a time finding it. Maybe I just need to get acclimated to it some more.
