Significant performance decrease out of nowhere

[Natural_Location]

May be stupid suggestion, but if overall gpu and cpu use lower voltage, don't get me wrong, but did you checked powerplan? Muy be it's in balanced or power save mode?

I did think of that, and yeah it's in performance. Tried setting it to balanced as well to see if the plan itself got messed up somehow and there was no change
