its true... the witcher 2 forest area in act 2 looks superior to anything I've seen in terms of foliage compared to the witcher 3. Sad but true.
some what true :/. in the witcher 2 grass doesn't react to the character or the wind though. also some of the foliage in the 35 min demo was great, especially in the swamp (though we cant expect it to look exactly like that anymore).
