The Switch version holds up surprisingly well, though the PS4 version obviously looks far better.
We finally got to see Dragon Quest 11 S, the Nintendo Switch version of the excellent JRPG that has been a long time coming. What we saw looked good—it was basically the same game as the PS4 version, but on the Switch. The PS4 version has a striking art style realized in Unreal Engine 4, and seeing it brought to life on Switch as is was impressive.
A new video, courtesy of Twinfinite, compares footage from the Switch version with the PS4 version. Side by side, it becomes apparent that the Switch version is (obviously) not exactly as good looking as the PS4 version is. Barring one example where the Switch version seems to have better mid-range draw distance when the hero is out on the overworld, the Switch version very clearly has poorer textures, poorer lighting, and poorer shadows. How much this bothers you will come down to your own tolerance for these kinds of things. However, I personally feel the Switch version holds up remarkably well given it is running on what is essentially a tablet.
Dragon Quest 11 S launches on Nintendo Switch next year in Japan; the game is also available now on PC, PS4, and in Japan only, on Nintendo 3DS.
