Have a nice day.

My iphone 8 performed better on games than my iphone 13 pro max. Its sad! I have good internet and LTE. My iphone 8 will play the exact same games at the same time and no issue but this phone lags horrible even on fast wifi. Is there any settings I can change? Oh and this was going on before IOS 16 and it hasnt changed since the update.
