Hi there.
Sorry to know that you are having troubles with your GPU. I have a 6700xt, which is mainly used for destiny 2.
Through many Adrenalin versions, I was able to achieve pretty amazing results. I think it was when I updated to 24.1.1, the same thing that you are mentioning happened to me. My solution was to got to the beta 24.2.1 and to change some OC/UV settings I had.
Right now, my gaming experience is pretty good, almost zero crashes. If you are undervolting your GPU, try to do so less aggressively, that gave me the best results. You can always try to roll back to a stable Adrenalin version, like 23.11.
Hope this helps. Regards - Kahlimdor -
