Sudden fps drops in valorant

I own the Asus zephyrus g16 gu603vi (i9 13900h rtx 4070) and I only play valorant. Since the day I recieved the laptop I got major fps drops ranging from around 150-400 in the range and ingame between 70-300. I even plugged a external monitor and I recieve suprisingly even worse results. Any advice would be appreciated.

Update: I refunded the laptop
