Medal of Honor:Pacific Assault physics videos.. very impressive stuff..
Water with ripples and nice looking reflections ,and Characters ragdolls animations ,
very detailed jungles ,and many other cool techniques and effects.. Havok physics its used heavily in this game too.. its great to see that advanced physics engines will be the standar in all games.. Hl2 .MOH:PA ,Painkiller are just some examples of games using Havok Physics engine.. other games using their own engine.
for the people that still have not seen MOH:PA videos ,here is a link..
the "nature" demo shows heavy uses of physics..
