So they are able to scale down The Witcher 3 to make it run on Switch without bigger performance issues but I'm supposed to believe that they have issues with making another game run on a more powerful system?
Seems doubtful.
Even if X1 was the reason, they decided to make a version for the console so they should've done some more testing prior to that.

They are probably fighting to make the frame-rate stable without having to go below 720p. Once again Jedi was 720p and had frame-rate issues.

Yeah but a) nobody is forcing them to release a game at a minimum of 720p and b) they could still make performance (and resolution) adjustments post release.

It's not the first time we've seen games running far better after a couple of patches.
