Witcher 3 is just visually poorly designed.
Any coherence is lost after about 20m when that blue fog sets in to cover up the laughably low draw distance.
Then there's the clothing that everyone wears, like it was the most bright piece they could buy and always looks fresh and like it came straight from the factory.
These few "vibrant colours" are either completely out of place or the effect is lost instantly due to technical limits.
This game is just ugly.
But whatever makes you happy, i am just enjoying the game a ton.
