Water looks very nice in that video and it's great to see the vessel react to the waves, though I'ld expect the vessel to have a bit of momentum. It looks like bobbing around like a cork not like a 100ton barge. (I'd be hurling my guts up in that sort of situation
)
Still its great to see innovations like this in a sim.
Hopefully one day we'll get something like this in the IL2-II series. Imagine landing on an aircraft carrier with it bouncing around like that!
