Eh. It's funny but the same effects cause WWHD to slow down as well (explosions and flames and what not). Game looks stunning however and I will be getting it day one - on NX lol.

If I remember correctly, the slowdowns on the  original WW were kept in the HD version on purpose because attempting to fix it ruined the game's physics in certain parts of the game.

WWHD's simulation is indeed tied to its framerate, which would've made 60fps play in double speed, and is why they stuck with 30fps, but that's not the reason for its drops below 30fps. These occur when the game couples heavy use of alpha effects like explosions with its full 1080p framebuffer, which bottlenecks Wii U's memory bandwidth. You get similar but milder dips in Twilight Princess HD, another native 1080p title, when alpha effects fill the screen.
