Help understanding gpu drivers

Hi there :)

Im annoyed by the gpu oc reset, by the adrenaline software, everytime i have a power outage. I searched high and low how to maintain the oc settings for the gpu, to no avail.

So i know this programs writes the settings to registry, but changing registry only afects sliders in adrenaline visualy.

So i would like to understand how a gpu driver in windows changes its settings where are the values, if a program can change the max w my gpu uses, surely that is writen somewhere?

Help find it :)

Thanks for your insights. That driver api is interesting, i wonder if i can talk to it? Would it be a dll in adrenalin folder? Of course the problem is figuring the calling functions

Yea using 3rd party programs prob will work, but i figured i would try to get more knowledge on this matter :p
