The absolute worst is the little gaps you make by pulling down the wooden boards, shes more than twice the width of the gap with the ghillie suit looking armor on, let alone the backpack guy you're with at one point who is about 4 times the width of the gap ha.
You play games long enough and you know these things happen, its expected, but its still much better than it was in the past nowadays generally so when you see egregious examples like that in an otherwise pretty immersive game it stands out.
