Question Fps not what I feel it should be and not sure why.

So ive been playing games for a long time now and i just seem to not be getting the fps that I should be getting like people with lower performance components will be getting way more fps then I would be getting, I recently got a 1440p monitor which i know obv takes a bit more performance to run but even before I swapped over to it I was still getting terrible fps, I would average around 125 fps in warzone 2.0 ( I know not the best game to be looking at but again people with worse hardware are getting more fps then me) also tarkov I would prob average just about 115fps also again people with worse stuff say there getting more fps then me, like i feel like my pc is more then enought to be getting a good lot more fps then me, i have messed around with pbo with my cpu to underclock it and keep temps down so im not thermal throtteling or anything, Ive looked at temps and they all seem perfectly fine not even going above 75c on games and in cinebench would hit around 82c, gpu temps are perfectly fine aswell. so if u have any idea i am all ears thanks..... am i just overthinking ? XD
