The character model is between decent (in game) and good (on cutscene), but the background graphic are bad (like PS3 era graphic) . On top of very blurry because low resolution (as expected). Overall is a decent port but compared to doom is slightly better , also the reason why it looks like a good port because the games it self is lack of freedom of exploration and open area and more linear. But it's a good one, i prefer the look of Wolfenstein 2 because wolfenstein 2 on Switch play very smooth and still keep the graphic stable.
Edit: The cutscene actually not real time on Switch so it's explain why it looks good
