[TPU] microsoft refines directx 12 multi gpu with simple abstraction layer

Microsoft is sparing no efforts in promoting DirectX 12 native multi-GPU as the go-to multi-GPU solution for game developers, obsoleting proprietary technologies like SLI and CrossFire. The company recently announced that it is making it easier for game developers to code their games to take advantage of multiple GPUs without as much coding as they do now. This involves the use of a new hardware abstraction layer that simplifies the process of pooling multiple GPUs in a system, which will let developers bypass the Explicit Multi-Adapter (EMA) mode of graphics cards.

This is the first major step by Microsoft since its announcement that DirectX 12, in theory, supports true Mixed Multi-Adapter configurations. The company stated that it will release the new abstraction layer as part of a comprehensive framework into the company's GitHub repository with two sample projects, one which takes advantage of the new multi-GPU tech, and one without. Exposed to this code, game developers' learning curve will be significantly reduced, and they will have a template on how to implement multi-GPU in their DirectX 12 projects with minimal effort. With this, Microsoft is supporting game developers in implementing API native multi-GPU, even as GPU manufacturers stated that while their GPUs will support EMA, the onus will be on game-developers to keep their games optimized.


More GPUs better than one. ( No, not You Intel )

You know, it would be REALLY interesting if the new XBox came with dual Polaris graphics chips in it. Dont think a dual GPU setup has ever been done in a console before. And while I still love single GPU for how much smoother it is, forcing dev's to make use of multi-GPU config for the performance they need would be pretty nice in the long run.
