So i got a ROG G503 GE Strix edition which is preety good for the price i think,but after having this laptop for 4 months,the fps drop from 150 to 40 fps (rainbow 6 and dead by daylight),now even though i charge the laptop or not charge the laptop,its still the same. I've updated all my driver,bios,checked for virus but theres nothing change about it,is this a battery problem and if so should i bring my laptop to asus service?
