The lag has nothing to do with the iPhone. So, any iOS update won’t help with lag in PUBG mobile. The reason for the lag is game optimization. Tencent needs to update PUBG mobile and optimize for the 12 series of iPhones.
this same issue was with when the Note 20 Uktra was first released. Lagged like crazy but now runs 90fps smoothly
