r/linux_gaming on Reddit: A little help for a newbie with CoreCtrl
July 4, 2020 -

I literally just switched over to a Manjaro KDE build yesterday. I've dabbled in the past with Linux but only for basic tasks, never for gaming and the like. I heard it was finally prepped for gaming and so far so good but one thing was missing. I missed my Adrenaline drivers and software, cure Corectrl, even the UI is reminiscent but there's one issue.

I have a Vega 56 GPU and a 3700x cpu and while I've got basic functions like fan curve etc on the GPU I don't have voltage regulation etc and my GPU shows up as a generic. Is there any way for me to change this and get full access?

I hear it's possible but the explanations I see when searching turn up mostly guides that assume you know how to do what they're explaining. Can anybody put it simply?
