(Ask) In Game Issue

[Tunamayo]

Hi, I have some trouble when playing this game. Before that I will bread down my laptop specification.

ASUS TUF Dash F15
11th Gen Intel Core i7
NVIDIA GeForce RTX 3060

I think my laptop are strong enough to play this game smoothly with high graphics setting, FYI I always playing heavy game with charger always plug in. But recently, in the middle of playing this game my charger not charging suddenly it makes uncomfortable because my fps will drop. Before I play this game, I also playing Naraka, which is more heavier than this game (I think) but I don't have any problems with that game.

So, Is this my laptop have some malfunction issue or the system of the game I got?
I like playing this game and maybe I can get some suggestion or answer from my problems. Thank u in advance
