A feature I am very curious about since I can enabled Intel's iGPU, or install the 680 that I have lying around. Anyone care to give any experience that you have had with this DX12 feature? My main concern is screen tearing. Edit: Forgot...what about legacy DX rendering? Such as a DX9 game with multi GPU rendering is a curiosity too. It seems that multi-rendering may only occur with DX12.
