CPU usage and FPS spikes

This is how my performance Graph looks in the main menu:



It's the same in my Hideout or any other zone. My CPU is spiking every second and my GPU is basically doing the same thing. I think this started happening after I ran a few 5-ways yesterday, where my PC was struggling a bit to keep up. I have tried other games and tried to look for anything that looks wrong in HWinfo, ran benchmarks and diagnostic tools, but can't find anything, it seems to only be happening in PoE

(This is happening in the Steam and in the Standalone version btw.)

Seems to have fixed itself.
