The vault is nearly open. In the brink of the "Fallout 4" release come details of the graphics and mod tools that fans have to look forward to in the post-apocalyptic adventure game from Bethesda.

According to a source from WCCF Tech, the upcoming "Fallout 4" will feature technology from Nvidia's GameWorks library. The tech company, which is primarily known as a manufacturer of graphics processing units or GPUs, has been collaborating with Bethesda to create effects for the new "Fallout" installment.

The effects reportedly range from ambient occlusion to shadowing and lighting effects, but it has not been revealed if the GameWorks influence will be in the game upon its release or it will be part of additional patches afterwards.

While new details are often met with pleasant surprise, Nvidia's participation in "Fallout 4" might make experienced gamers concerned because of its history of allegedly taking control of various games and ultimately compromising the quality and performance of AMD hardware.

Fortunately, the source from WCCF Tech revealed that the "Fallout 4" partnership of Bethesda and Nvidia would take the path of "Grand Theft Auto V," which was well-received and featured good collaboration between GameWorks and AMD.

In other "Fallout" updates, Bethesda vice president Pete Hines went on social media to explain "console modding" after an inquiry by another Twitter user.

"Mods will be playable on consoles," Hines wrote on his Twitter account. "The mod tools will not be released on console."

Many "Fallout" enthusiasts are looking forward to mod options available to them, but it seems as if Bethesda will be limiting modding to PC users only. However, the developer has promised extensive mod support much like in the best-selling "The Elder Scrolls V: Skyrim," as game director Todd Howard said in an interview with IGN last summer.

"So, just like 'Skyrim', there are mods that can break your game pretty wildly, and so we have some safety things on the console for that, but at the same time, we are going to let people break their game," he explained. "Because we try heavily not to."

Furthermore, the director confirmed that the team behind "Fallout 4" wants to offer as much freedom with the mods as possible.

"The plan is that it goes through Bethesda.net, but ... outside of things that we would normally take down - we take down things on Steam Workshop if it's got things that are illegal, or things like that - we'll do the same thing," Howard pointed out, adding that they'll only be strict with illegal content including taking assets from other games.

"Fallout 4" for PlayStation 4, Xbox One and PC will be out on Nov. 10.
