Prior to GDC 2015, we’ve heard various rumours suggesting that DX12 would support multi-GPU configurations from different vendors. And while we did not hear anything about it at GDC, a Microsoft technical support staff member claimed that this feature will be supported by its latest API.
As we can see below, Microsoft’s representative claimed – when asked about the possibility of DX12 supporting multi-GPU systems from different vendors – that DX12 will indeed support such a thing.
This image was originally posted at LinusTechTips. As always, we strongly suggest taking this with a grain of salt until Microsoft officially announces such a feature.
Enjoy and stay tuned for more!

Still, the PC platform won him over consoles. That was mainly due to 3DFX and its iconic dedicated 3D accelerator graphics card, Voodoo 2.

I don’t really care about this, i care more about sli/crossfire game compatibility. If 2 GPU can give me about at least almost 2x the performance of a single GPU on every game out there and it gives me no stuttering or weird sh*t happening in the game, then i would be more than happy.
Linus, such a nice guy
Just don’t let him touch anything breakable…
All I need is the ability to combine the VRAM of my both GPUs in SLI,so I can have 4 gigs. 😛 That alone would make me transition to Windows 10 almost immdetiately.
yeah this is gonna need more than dx12, they would need to allow it in the drivers themselves, which they wont
