I understand, maybe future updates will improve game performance. I don't use the phone much to play games, but if I find optimizing the kernel for the temperature, I'll notify you here

Glad to hear that it works relatively well for you, I guess it could be optimization issues in pubg. I remember PUBG New State running me with frame drops before testing this ROM.

I'm installed but continue showing boot screen tell me solution

How long has it shown the boot screen? First boot always takes a while and since it's on the boot screen nothing bad happened I think. In my experience it would never get the the boot animation if it has a problem.
