Take a look at how well Blood and Wine holds up on PS4 and Xbox One.
The Witcher 3: Blood and Wine - see how PS4 & Xbox One stack up against one another
The Witcher 3 Blood and Wine expansion seems to show improvements to CD Projekt RED's tech on consoles.
The most recent analysis by Digital Foundry puts the PS4 and Xbox One releases against one another, as well as PC. For consoles, the PS4 version has small edge, but both adhere to the 30fps target fairly consistently.
Blood and Wine runs at the same resolution on each respective console as the original did, 1920x1080 on PS4 and 1600x900 on Xbox One. Texture quality is the same on both, and they match the PC's highest setting. The main difference between consoles and PC is in draw distances, with better shadows at long range than on consoles.
Both PS4 and Xbox One drop frames when streaming in new areas, especially as you approach the big castle. Xbox One averages 28-30fps, while PS4 is mostly 30fps.
