My GPU usage drops alomg with my FPS when playing games.

I have no idea why this is happening but most of the time it follows the same pattern: when the game requires more gpu usage the usage drops.

neither my cpu usage or ram is at 100% so it is not a bottleneck (i believe).

i would really appreciate some help as im getting kinda hopeless.

my specs:

11th Gen Intel(9) Core™ i5-11400H @

NVIDIA GeForce RTX 3080

16Gb RAM

if anything else is needed i will specify it.
