The WildStar site has been updated with a new blog post that is mainly centered around screenshots to that show off pairs of images to show improvements made that will arrive with Tuesday's F2P launch.
Where before large sections of zones had sort of flat single-point lighting, we’re going back and making it more realistic by increasing the number of sources that light up the environment. We've also added effects such as the rays from an otherworldly star—or a glow from a campfire—that all go into bringing the look and feel of an environment together. While still fairly time-intensive, it’s allowing us to make some dramatic improvements to the visual quality of the game without needing to touch the already high-quality models and textures in the game.
Check out the full line up of screens on the WildStar site.
