This is my first post, but simple google search can't find relatable issue like mine.
Check out the sample video of the performance of my PC here: Adrenaline insane stuttering - YouTube (Sorry if the name isn't stuttering, idk what to call it). Before this, I also tried the previous versions of Adrenalin drivers but it's the same. I didn't try driver versions before adrenalin up until 17.7.1 since this version works best with the game I play most; Overwatch.
I tried clean install using DDU, also tried direct upgrade from 17.7.1, without messing anything (I also didn't mess with anything in 17.7.1).
Any help would be appreciated.
