Difference is subtle. It is more obvious in the bad weather condition. Besides more wave crests I see that the water is more wavy (with the stocks one is the more flat), also tiny bit of different scattered light on the waves (could be because of "deeper" waves).
Thanks Sergey
I'm not sure that there is water higher than 4, maybe to try 6, if it doesn't turns back to 4 or 5, I would say that it don't works, also number 5 don't works, just that the game don't turn it back.
