it's streamlined like in TW3. And there were proper animation mods for it later on so I expect maybe the same thing happens here. But I think that they could've at least placed some kind of audio feedback for using consumables right now.What i am troubled with is the fact that Drinking/Eating using substances Is not animated but in very few quest related situations, I want to sit in V's crib and drink the damn good looking stout i have in my inventory!
Or go to a damn restaurant/Bar and see V down some shots! Or food!!!
