The update on Wii U did help a bit. Shrines and just normal running around in the world are almost always 30fps now, same with Zora's Domain. Weather effects still drop it a bit though. Korok Forest/Kakariko Village/using Magnesis, Cryonis, or Stasis still make the game plummet to like 10fps.
This basically fixed a few minor problems but none of the major ones. It's a good start however and hopefully it fixes the random freezing and crashing that I get more often than you should (which is never). Now to see if they can at least make the game have a bottom cap of 20fps (AT MINIMUM) and reduce pop-in, and remove the occasional random floating object and this game could maybe raise up to a 9/10 for me. Still no way it's gonna get to a 10/10 though.
