    Sooo.

    I have read some articles about DX12 Split Frame Rendering for Multi GPUs in the recent days.
    For anyone who doesn't know what Split Frame Rendering is a quick compare to Alternate Frame Rendering which is mostly used today:

    I know that in DX10 and DX11 you have to specially program in the SLI and Crossfire Support to really gain form it.

    I searched but nowhere I could find an answer to this Question:

    Do we have to specially program support for SFR in or does DX12 do the Job automatically when more than one GPU is detected?

    I hope someone knows a bit more.

    Please excuse my broken grammar.
    German is my first language :)

    Maybe the screen spilt into many parts(tile) and each gpu draw the one part then all parts combine togather.

    And aren't AMD bringing out a VR GPU which is two Fury X cards packed into one board.

    This could be amazing for VR.

    I would guess that it is a feature that Unity will need to include either under the hood or as an option.

    As far as I know the SFR is only part of the explicit multi adapter. So it is all on the devs.
