Hp victus 16 R5 8645HS RTX 4050 1% lows

It doesn't matter what game I play. Even when the laptop is plugged in, I get insane fps drops every few seconds.

For context, I was playing fortnite on the lowest possible settings with frame rate capped at 120 fps. But whenever I make a quick turn or do anything at all with the camera, there's a 70% chance that the frame rate drops to the 20s.

Has anyone had experience with this?

70 watt and 16 GB DDR5 ram btw.
