Believe it. Though I think BOTW sounds great given user impressions and reviews, game critics often give Nintendo (and Zelda especially) a by. It's ridiculous, but it is what it is. Amusingly, the Gamexplain review (a channel that is very Nintendo centric) was more critical of the performance than most outlets, and the Easy Allies review was refreshingly upfront with the issues as well. I expect Nier Automata will get pretty great reviews from mainstream outlets since the review guide apparently explicitly tells reviewers not to stop after the first
and the game appears to have the one thing Nier really needed most (excellent gameplay), but I am sure performance will be cited as an issue by outlets that ignored the worse problems BOTW has. We already have the enthusiast/import/early reviews noting performance despite loving the game, so the bigger sites will surely bring it up here and there. And hey, maybe some sites played Zelda in handheld mode mostly, in which case they wouldn't really be able to notice it's performance issues as much.
