I also remembered you stealth editing out Capcom messing up technically but truth be told no Japanese developers so far this gen has shown to be technically proficient ... (almost none of them are pioneering new technical standards and they don't want to make specialized console engines either like big western publishers)
1080p/60fps games on PS4 are ideal for Switch so I guess RE7 is a good fit. It's just too bad that there aren't many of those games that perform that well on PS4 ...
I stand by it; MHW looks nowhere near good enough to be stressing the PS4 so any performance issues there are Capcom's bad.
But a game doesn't need to be 1080p/60fps on PS4 to be portable to Switch. Games with that much headroom would be easier, but as Rise of the Tomb Raider's 360 conversion demonstrates, 30fps titles are not off limits.
