The Legend of Zelda: Breath of the Wild is the current obsession in my house, with my brother playing the Wii U version and me and my fiance fighting over the Switch version any chance we get. That said the game has some significant framerate issues, which the new v1.1.1 patch thankfully addresses to a degree.
Gamexplain does a side-by-side comparison of the game before and after the patch, and while some trouble spots are smoothed over, others like the foliage-heavy Lost Woods still tend to chop quite a bit. It's not a dealbreaker by any means but it does diminish what is overall a phenomenal game. Check out the video below for more info.
