Randy Pitchford is on stage demonstrating a Borderlands 3 tech demo. He talks about how they developed some new technology that maximizes the performance and visual presentation of the game running on AMD hardware. Randy shows examples of various locations and what they were able to do. You get a glimpse of the various planets and their environments. We also learn the name of a new planet that we will be visiting in the game.
Not visible in the presentation, however, we learn about Eden-6 in the gameplay demonstrations that are going on at E3 2019. Check out the other breathtaking environments.
