E: ah darn, seems this does cause some minor issues with certain things in game (namely map & cutscene effects), thanks to theboy181 for letting me know, who has tried making a res patch for it in the past, sadly seems it would take a lot of work to fix all the shaders etc - too bad, since as the comparison below shows, letting game scale itself does fix a lot of graphics issues :(
If you aren't bothered by those minor issues this still might be useful for some people though, who want the game to look its best, so I've left it up here.
So yuzu's resolution scaler is pretty awesome, but sadly XC2 has some issues with it causing weird lines to appear pretty often, decided to try looking into the game exe to see if a patch could be made to change resolution there instead, luckily wasn't too hard to find where it was setup, and with that changed the game seems to scale up fine without any weird artifacts :)
