I am more concerned about the environment of the game. I like the more realistic environment, the sea, the sky and the clouds. Waves with different wind speeds, environments in different climates, and splashes and wakes of submarines.
SH5's clouds are too big, the proportion is wrong, the sea level is smaller, and there is also a lack of high-level clouds. So it's unrealistic.
I hope UBOAT can solve these problems.
In the UBOAT video, when the submarine was submerged, the watchtower could not see the spray. I think it's unrealistic.
Why is there water spray in SH5 omitted in UBOAT?

But I still want to thank UBOAT studio for its hard work. UBOAT's waves seem more realistic than SH5's.
