　　Because its “tech team,” the developer explains, “is closely aligned with the art team,” it was able to devise features based on specific art and performance goals that each team wanted to achieve. Of these features is a physically based deferred renderer. With this, Bethesda was able to make both objects and inhabitants of the post-apocalyptic world feel “tactile and grounded.” The way metal reflects light, for example, should be different from wood.

　　Then, to create volumetric light, or “god rays,” Bethesda worked with Nvidia to make the world feel more alive. Notably, Bethesda has retained close relations with Nvidia ever since the graphics company aided in the development of the water effects in The Elder Scrolls III: Morrowind, which released in 2002. Volumetric light, which Bethesda describes as “spilling across the scene,” is heavily reliant on the GPU’s hardware tessellation. Put simply, it adds extra depth to the atmosphere.

　　And, since the player can travel around freely, regardless of time or place, there have been dynamic post-process techniques put into place solely to improve the color vibrancy of particular sceneries for what Bethesda says is “maximum emotional impact.”

　　That’s not all that’s been improved, however, as Bethesda has released a complete list of technical upgrades to its Creation Engine as denoted below:
