Rise of the Tomb Raider is the first title to implement explicit MultiGPU (mGPU) on CrossFire/SLI systems using the DX12 API.  It works on both Win32 and UWP.  Using the low level DX12 API, Rise of the Tomb Raider was able to achieve extremely good CPU efficiency and in doing so, extract more GPU power in a mGPU system than was possible ...

Ashes of the Singularity makes gaming history with DirectX 12

Bryan Langley October 27, 2015 Oct 27, 2015 10/27/15

Back in April, we described Multiadapter, a DirectX 12 feature which gives game developers the power to light up every GPU on a user's system.  Prior to this feature, developers had to rely on help from hardware vendors to use multiple GPUs, with the restriction that the GPUs be homogeneous. DirectX 12 removes all such limitations.  In our...
