Ubi is being crappy nowadays, but putting the blame on them for this is pretty naive. All publisher and all games present bullshots. Not even the PC or PS4 versions matches the screenshots. Run the game at 4K, downsample and photoshop it to hell, that's the rule. Sony, MS, Nintendo, EA, 2K, all games are a bullshot festival.

Want to know the real visuals? Wait for gameplay videos on YouTube (and of course, ignore the compression ruining the textures).

Edit: BTW, these comparisons sucks. The shots aren't even in the same lightining conditions.

You can count on the PC version being basically the PS4 version with minimal upgrades. Bullshots are usually made at very high resolutions and sometimes with better quality assets that won't be used in realtime builds. And after that, they use a lot of Photoshop and post-processing to make it look better.

NeoGAF has a nice thread called "1FPS bullshots" or something like that. Guys run the game at 2 or 3 fps on 8K resolution, downsample it and use Photoshop.
