Ios 15 framerate issue on iphone 12/13

hi,

i am getting feedback that my game is lagging on iphone 12/13 on ios15. it runs smoothly on an iphone 11 with ios15 but i can’t unfortunately test it myself on newer phones

is it just a matter of updating xcode? my game runs well on higher fps on my macbook. or is it best to limit the fps with targetFrameRate?
