Assets are presented in spectacular way. Geometry, nice textures, particles, lightning, fog effects... Environments are super dense, there is not a flat surface is sight [DF mentioned that game uses tessellation to displace as much geometry as it can], everything is either filled with complex gothic architecture, or ruined in combat, or wasted by nature, or made from natural [uneven-looking] structures. Modeling, effect and lightning crews really did a an amazing job.
The only bad thing is aliasing [+shimmering] and framepacing [minimal framedrops are really not an issue, those occurrences are too rare]. RAD and Evoluition are still holding the crown of games with "perfect IQ presentation" on PS4.
