The game is running at 1080p and could do 1440. The resolution scaling can be finicky on this game. I had to keep changing it till it finally scaled properly. I had that issue on the Ally as well.

I locked the framerate to 60 because I have a 60hz refresh rate display. This game can get over 100fps. A lot better than the frame rate I got on my 1060 6b at low settings which was under 60fps at below 1080p. ? Btw I haven't played this game in a while so my playing was horrendous.
