could it be a hardware issue? Did you try unplugging and plugging the VGA power cables back to reset the GPU?

Just like last night with 16.4.1, I had a BSDO while installing 16.4.2 but still managed to go through. Testing it right now.

I think it's safe there because there's no way to adjust voltage. The worst thing that can happen is just artifacting and crashing.

You mean this?

Something I noticed with Crimson. The RivaTuner Statistics Server detects it as a game and shows hardware statistics on screen.

Actually, the old catalyst UI is still there within Crimson under "more..." which I think are the other options you are looking for.
