According to Nvidia, the  Vault 1080 mods brings an even better feel to the game, by adding volumetric lighting, more realistic shadows, HBAO+ with ambient occlusion control and more. The mod also adds weapon debris as well as new meshes and materials, so it should look really impressive, at least judging from a couple of published screenshots.

Nvidia also says that the Vault 1080 is a big mod, equal in size to other vaults in the game and should add about an hour of gameplay.

The Vault 1080 should be available at Bethesda.net on September 2nd.
