Ok! So I attempted to switch the graphics card in AMD per the link you provided. Unfortunately, my version of AMD Adrenalin doesn't contain the "Switchable Graphics" feature anymore - see the attached screenshot. I did some quick googling and it looks like they removed that function from recent updates to the application.
Another thread online discussed using graphics settings, under the display settings on windows, to specify graphics chips for certain applications. I used that to specify my "High Performance" graphics chip - the AMD R9 - for DAI, see the second attached screenshot.
I was really hoping that would fix the issue. Unfortunately, I just booted the game up twice and had two subsequent hard freezes within five minutes of gameplay. The problem is persisting unabated.
Any other ideas?
What AV and anti-malware software do you use? That can have an impact as well.
