This is exactly the question I wanted to bring up today, with the exact image
It might be "just" an eye candy, but it's all connected. If I'm in command of something with displacement of 20k>, I want to feel like it behaves like such beast. I really, really can't stress out how important it is for me (as well with other things), because being kind of sloppy on this end is the exact reason why I tried and thanks-maybe-next-timed World of Warplanes - because it feels like pew pew RC planes.
I would really like to see shockwaves of all kinds, huge explosions of ammoracked ships as well as %chance to break the ship in half upon sinking/rolling over and stuf. Dramatic weather changes with limited visibility and smoke effectiveness, various main battery and engine sounds, you name it. Sure, it should be optional in graphic menus, but who cares of FPS on this kind of game, as long as it runs 30+? Don't get me wrong, I'm 60+ FPS whore, but I don't get the feeling this game will ever have ambition to be competitive and thus doesn't require to have a stable 60+ fps (like on WoT, which Wargaming tries to make kinda "competitive" and where the action is often rather fast and requires smooth gameplay).
