Complete sky overhaul with new night sky textures by me, clouds by Marcurios, and sun textures by Prod80. Fallout New Vegas is an old game at this point. try uninstalling ENB then run new vegas temporarily, if it works, we can go from there, but if doesn't work, it's not ENB. Discussions for New Vegas began between Obsidian and Bethesda in 2008/'09. To bring up the ENB menu in-game press Shift+Enter This will show the ENB menu on the top left corner of your screen, you can use it to disable or enable features from the ENB.
