    Microsoft to make multiple graphics cards easier w/ DirectX 12 update

    One of the most exciting aspects of DirectX 12 is that it allows users to pool together different video cards, with different models and performance, to improve a systemís power. But so far, that promise has only been sporadically fulfilled, because itís up to developers to support all the coding needed for this feature to work. But Microsoft is about to change that.

    Explicit Multi Adaptor (EMA) support is the feature that allows DirectX 12 cards to work together, regardless of their maker and performance. Unfortunately, very few titles support this feature, so most users can't really take advantage of it. Thatís because EMA is a low-level tool, which offers great performance boosts if used properly, but is tricky and time consuming to implement. It can even degrade performance if used incorrectly.

    Now Microsoft has confirmed that itís taking away some of the complexity in multi-GPU systems, with a new abstraction layer. This will allow developers to take advantage of multiple GPUs on a system with only minimal coding. Of course this is only "basic multi-GPU support", so developers looking to access the full power inside of your video cards will still need to implement EMA properly...

    LOL, this is funny. Perhaps Microsoft finally figured out how difficult MGPU support is in Direct X 12 from their own Microsoft Studios, since after many promises GOW UE still doesn't have proper MGPU support more than 4 months after release. Do Microsoft and game developers (the console crowd) really care? Doesn't seem so from the total Direct X 12 MGPU failure over the last year. Nvidia/AMD pay the price for this. Here is my message (and many of the other PC gamers I know) to Microsoft's Direct X 12 team when it comes to MGPU gaming:

    "The thrill is gone, baby, the thrill has gone for good." Awaiting my 1080 and there will never be two of them in my PC.

    RIP Gary Moore and for me RIP Direct X 12 MGPU gaming.
