Before you went back to the old style beta drivers, did you use DDU to clean everything? If so, you might try that so that CCC runs. I have a fury, but I do not own Fallout 4, so I cannot test how it performs for me.
I used the AMD clean uninstall Utiliy, i could try with DDU to get CCC to work; However that isn't the real issue, I just added that for completion.
What I really want to know is whether I can, or will be, able to run Crimson without these issues.
I don't want to have to stick with Catalyst indefinitely.
I will try running DDU, then Install Crimson, and see if things improve.
AS for Fallout 4, i don't have all the issues other people seem to have with it in Crimson, just the wierd framerate drops, which happen across multiple games.
Update: Ran DDU, installed crimson, problem persists.
It is as if the card downthrottles too hard, or has a hard time settling on what speed it needs to run at to have a stable framerate.
It happens in all games, the same principal, in different degrees. Just Cause 3 as well.
Running DDU again and reverting to catalyst.
Yeah I am having a lot of issues with running one Fury X on the new crimson drivers. Frame rates fluctuate as do the speed of my graphics card. On previous drivers the card would fully boost to 1050mhz when anything 3d related was being rendered. Now the speed changes and causes a lot of framerate drops and such. I've also noticed a lot of graphical glitches when running a game with v-sync on. If I disable v-sync the performance is better and the graphical glitches go away.
I actually have 2 Fury X's in crossfire and every game that uses both cards runs great and my cards boost to 1050mhz and stay there while playing a game with the new crimson drivers. I am just having a lot of issue when running games that don't support crossfire. So your not along in having performance issues with the new crimson drivers. I would try disabling v-sync the next time you try out the newer drivers and see if you get better performance. It helped a little in my case. For now though I've gone back to previous drivers because most of the games I am playing at the moment use only one card.
