I totally agree with you that the game looks great. Those cinematic shots are truly beautiful. But I can guarantee that BF1 will look even better. They used Photogrammetry to capture assets to use in the game which basically makes objects look lifelike. The technique makes it possible to get the full 3D representation of objects, both the ‘wireframe’ as well as the texture. They first used it in Battlefront and I’m sure you can tell the difference in quality.
My colleague made a couple of objects like trees and rocks with this technique and put them in a 3D world. Then we played around with the HTC VIVE and I can tell you it’s really an amazing experience.
