There was also the problem of the polygonal glitches that occur once and a while. This is very evident when you stand next to a wall, and look down. Lara's head cuts into the wall and you can see what is on the other side. The walls, doors, trees, and anything else that Lara would encounter seemed to have an old dark texture to them. Improved animal character graphics surprised me somewhat, but not totally.
Human characters are another story.
Tomb Raider has had the same engine since the first game. This third-person view makes it interesting, but difficult to say the least. If you get stuck in a corner, and need to jump to the other side that you cannot see, just use the look button. But you need to let go of the button to jump. So your still jumping blindly.
