After updating my Nvidia Graphic driver to 337.88 all the planets dark side are literally dark sided! Gonna have to roll back driver until there a fix!
Thanks for this, what build is in PTE that has the fix for this? How will we know when this is fixed in the live version? EDIT: I see this is fixed in 66830: (sorry, as a noob user apparently I can't link to posts.) Just tried it out with Ambient Occlusion on and it's working fine now
