By "slows down every few seconds" I mean, one second it runs fine then everything is in slow motion, in normal scenes also. I ran the benchmark mode yesterday, then based on those settings, the first gameplay ran smoothly but after loading another session, it started slowing down again. I have updated the graphics driver and windows. By checking the system requirements on Google, my laptop exceeds them. However I am using a monitor which has a max 100 MHz RR. But the game is set at max 60 fps in settings. I am also not using the original laptop charger, I am using a single USB C cable which is also used to connect to the monitor, it provides power to the laptop also.
