What is your experience playing DS3 on the Steam Deck with an external monitor? what resolution do you use? What kind of performance were you able to squeeze out?

I’m currently playing at 1280x800 on a 4k tv and while this may not sound rather good, my couch is some meters away from the tv so in the end it’s not that bad (or I’m not that picky). I’m on high graphical settings and get generally between 50 and 60 fps. Would you recommend switching to 1920x1080?
