It runs 900/30fps on PS4 that either means the game is among the most demanding games on PS4. Or the code is very poorly optimised. Either way porting a game that runs 900p/30fps on PS4 and only in 1728p checkerboard on the pro to a device that is more than 5 times as weak when running in handheld mode is no small feat. At least with Doom you could cut the FPS in halve and the resolution at the most demanding points using a dynamic resolution.

How runs on PS4 doesn't matter because we most likely talking about bad optimization, SE said that Dragon Quest XI’s Western Release “Closer to Remaster than Update", while fact is that UE4 is very scalable and easy to work with, so all this is just SE problem, dont have nothing with Nintendo or even PS4 hardware.

The UE engine is generally easy to work with. But Square needs to optimise the Switch version a hell of a lot more than the PS4 version. That will take quite a bit of time it seems. They don't have a code they can just copy paste on Switch. If they had the PS4 version would have ran at 1080p/60fps. I mean they obviously could not optimise the Switch port, but it would look  and run pretty bad if they did just that.
