Fortnite performance is surprisingly bad on s21 ultra , I expected it to be 60fps constant maybe even higher on such a high end device but the fps is not great even when the device is cool . I have tried all 3 resolutions with all 4 quality presets ingame and messing around with the 3d resolution and even 60hz ,the best result I have got was 1080p high settings which got 60fps most the time but still dipped . I'm unsurprised a higher res and settings gives better fps due to cpu throttling but I believe 90fps was expected for this device . I have also tried all kinds of game boosters including Samsungs built in game booster priority mode on and off restarting the device and forced restarts to no avail , I have also installed the game driver and still not great . Everything is up to date I am playing on data but I don't think that should factor my fps and I'm not sure what to do or if I'm missing something or if it's a common thing but please help or give suggestions on what else to try.
