Lagging if playing PUBG mobile

I'd contact PUBG as it's more their problem then Apples

Good Luck

Thanks a lot. I'm used to getting hot. but I hope Apple does not degrade the performance of processsor if I get hot or warm. this seems like the kernel and thermal engine issues in apple are limited to a certain temperature. I have to bring my device to the fan every time I play games with high graphics quality
