On PC it runs at 60fps (there was a patch for that), and with HD textures.
Looks something like this (pic of early hd textures, thread):

Honestly the emulation on dolphine holds up very well compaired to the Xenoblade DE (switch) version.
The pop-in isnt as drastic too, in those videos of the Xenoblade DE, it was really hard not to get annouyed by foliage pop-ins.
