ArunYellapragada , via OnePlus 9 Pro , Nov 28, 2021 : Today they released 90fps option for iphone 13 pro max which launched 2 months ago... OnePlus 9pro launched 7 months ago and still they didn't released. I don't know why. I've think Pubg is not interested in OnePlus devices I guess. OnePlus team you need to look into this issue. I have mainly purchased this OnePlus 9pro for gaming but I'm unhappy now because of this issue.
