AMD is indeed supporting BF1... as seen in the Computex footage shown during the 480 launch (link below)
I'm surprised no has has really mentioned what was shown... AMD is partnered to the game and it also shows something called "Premium MultiGPU Support".
With all the doom and gloom about mGPU set ups, and lack of support for them, I would have thought more would be discussed about this.
My thoughts are... AMD + DX12 + VR = a resurgence of mGPU
AMD have already talked about supporting and partnering with quite a number of developers (dont have a link to that info sorry, it actually might of been during the same conference). And since they seem to be advertising this "Premium MultiGPU Support" thing, it leads me to believe that BF1 wont be the only game they will want to showcase as mGPU friendly. Logic says they would try and push it with as many games as possible.
Add to that the fact they showed a crossfire bench for the 480 AND the fact that they have also been pushing mGPU as the way to go for VR... we just might see quite a big effort from AMD towards supporting mGPU set ups.
Thoughts?
AMD is pushing Explicit Multi Adaptor in DX12 and we already have AoTS supporting it. This is not crossfire like many people think. If more games support mgpu then we could use AMD and Nvidia cards in dual gpu configurations. If DICE is supporting it in Frostbite we may get a brighter future for mgpu with DX12.
