The best news surrounded a new abstraction layer for game developers to utilize for multiple GPU support that MS would be releasing on GitHub very shortly. According to Microsoft, with only 'very little' code adjustment, DX12 titles should be able to implement basic multi-GPU support. Yes, the layer will be available in this repo. We will also be publishing two mGPU sample projects along with it - one using the layer and one not using the layer. We're making some final tweaks and doing additional testing and plan to post it all soon.
