Explicit DirectX 12 MultiGPU, the Affinity Layer helper library, and your game

Andrew Yeung - MSFT

Rise of the Tomb Raider is the first DX12 explicit MultiGPU (mGPU) title for CrossFire/SLI machines and it shows some pretty nice gains over DX11 implicit mGPU giving you the best possible gaming experience.  Read more about it on this blog post here.

We’ve had several folks ask us how they can most easily implement the same thing in their apps and get that kind of performance.  Well, we’ve just released a helper library called the Affinity Layer on our GitHub page to kick start your explicit DX12 mGPU implementation in your app!  There’s a sample that shows you how to integrate the library and if you want to take it even further, there’s a version of the sample that shows you how to integrate mGPU directly into your app without the library.

Take a look at the sample to get started here:

If you run into any problems, just let us know through GitHub; we’d be glad to help you out.
