Does gaming laptop performance decrease over 1 year?

So i own an ideapad gaming 3i with i7-12650H and rtx 3060 since august last year and its been 1 year. I used to get around 250-280 average fps on valorant last year but now i only get around 180-200fps avg(same graphic setting) the weird thing is that i hook it up with a 180hz monitor and i heard that it can boost the laptop performance, so im wondering whats the issue, does storage being used more decrease laptop performance?
