You won't be able to use DirectX 12 mGPU in linked node mode.
Can you disable crossfire on your Vega 64s and see the scaling when they are separate?
Actually, it was not supported at launch. It wasn't until people complained, as they originally said it would be supported when "announced", then they finally enabled it months later after launch. Which is exactly what will happen with the VII.
In fact, both Frontier & Vega offered crossfire enable options to link them together @ a hardware level for DX12 multi-gpu games at launch, it just didn't support actual crossfire profiles in games (which was why people complained).
