i am talking no physics, as in static rocks and "hard packed" ground (which i imagine the ground still has some physics to it).
as for non-static (dynamic or physic) objects such as fallen trees or logs. i find these to still be quite normal from what i have noticed and simply move when i drive on them allowing me to keep moving.
now does the camera actually have weight or mass which is giving an affect? i really do not know, but will agree it should not. only, i am not the only one to have noticed this and is something noticed since the original game. this is why i still feel there is something to this, even though by all rights there should not be.
