There's no denying that Call of Duty: Vanguard is a pretty game. Unfortunately, it appears that its aesthetics are working against it. Apparently, participants of Vanguard's Champion Hill Alpha are reporting poor visibility.
In terms of overall graphics, using the same in-game engine as Call of Duty: Modern Warfare seems to have served Vanguard well. However, despite the engine change, Vanguard is being plagued by the same visibility issues that are also present in Black Ops - Cold War.
This is definitely not a good sign for Vanguard as players are also complaining about how "boring" the game's take on the battle royale formula is.
Low visibility = camping haven
One of the biggest issues that players are facing in Vanguard is that the game lends itself to camping. Because of the low in-game visibility, it's become difficult for players to spot others, especially those who are lying in wait. As a result, campers are having a field day shooting down players that can't see them despite being just a few feet away.
