Like to see D3d12 MultiGPU support...!

The game as it sits now does not support Crossfire or Multi-GPU support. I say that because I just purchased over Christmas an RX-590/8GB card and have paired it with my existing RX-480/8GB card (purchased a year earlier) for Crossfire support in D3d11 and earlier, Multi-GPU support in D3d12. CD's Shadow of the Tomb Raider supports D3d12 multi-GPU support extremely well, and believe it or not multi-GPU scales ~98% > than the 590/8GB alone in terms of frame rate @ 3840x2160, my native res. Indeed, CD retrofitted 2015's Rise of the Tomb Raider with both a D3d12 exclusive fullscreen mode and multi-GPU support--which really surprised me.

So, it can't be that difficult to shoehorn multi-GPU functionality into a D3d12 game--I'm hoping that InXile will add this to their fix tickets...it works really well. Frankly, I am amazed at how fast exclusive d3d12 (not just bolt-on D3d 12 features for marketing bullets) is being picked up for games! About 10x faster than D3d9.0c was picked up, IIRC...;) Just thought I'd mention it!
