    DirectX 12 rumored allow AMD and Nvidia cards on same PC


    Microsoft's upcoming DirectX 12 is rumoured to feature a revolutionary API that would enable users to combine graphics cards from AMD and Nvidia.

    PC gaming enthusiasts could be in for a treat if the latest rumour from Tom's Hardware is true. So far gamers have been able to combine multiple AMD cards or Nvidia cards using Crossfire or SLI, respectively but they cannot be combined with each other.

    However, the latest rumour suggests that Microsoft could make such a combination possible and remove the dependence on manufacturer restrictions with its next DirectX release in Windows 10.

    Why would they want to do it? What's in it for them? Probably only result in really pizzing off AMD and Nvidia.

    It sounds like you could run two mismatched NVidia cards in SLI or two mismatched AMD cards in Crossfire. Software wise. Right now they have to be identical cards to use a bridge. I'm talking about desktop PC's, not laptops with hybrid crossfire or switchable graphics. I'm not sure I'd want to run an AMD and a NVidia card that way?

    I'd be genuinely surprised if a change in Directx, resulted in a change in how crossfire works- but who knows?

    It won't affect Crossfire directly. It's for when you can't use Crossfire. That's how I read it anyway. There really isn't a whole lot of info in there.

    I am going to speculate that you will be able to use 1 GPU as a number-cruncher, while the other GPU renders video- but like you said, there isn't much info in that article to go on.

    As far as I understood DX12 GPU aggregation will make possible the use of any combination of cards, distributing rendering tasks asynchronously according to each GPU capability.

Some of the games I have seen have the options to select which one to use, dx9 or 10 or 11. Honestly, I have just a little approximate knowledge of what these do most of them from experience. - dx9 runs smoother (just for me i suppose) - dx10 just adds shinys and i did not really use it....
