I'd been assuming that the ugly sheer horizon cut-off was the same for everyone. Then I noticed in the dev streams that they always tend to have that lovely haze in the distance, particularly noticeable down green valleys and such. I've never been getting that at all... [Creative mode after a clean start of the game in 22.214.171.124.] However the first time I came to show this I changed some settings and it begun working. I can't figure out what setting or combination of settings it was; after much much fiddling I can't get it repeatably. But once it's kicked in, it seems to just keep working on all the settings, and between game modes/menu... Maybe something like: Simplest then toggle the draw distance down to minimum and back up again.... But not that. Maybe it's semi-random....? Really vexing as I'm tying to record a new episode and attention to detail, etc.
