13 Pro Max fps drops in guided access mode on

Hello,

There is a problem with 90 fps on iPhone 13 Pro Max/ 13 Pro /14 Pro Max / 14 Pro while playing PUBG Mobile, cod Mobile and other games when you switch guided access mode on. Game is not stable, fps drop down below even 60 fps (around 40). When I try to put it on 90 fps with guided access mode on game becomes choppy and it’s not 90fps. This Bug is well known by community, even profesional players know this bug, but there is no official answer what is the problem about. Please let community know whats wrong. Its not about game - i have contacted game developers and they say its about apples side . Lags and fps drops on 90 fps mode happen only when you switch on guided access mode. Help us
