[WinBuzzer] Microsoft Simplifies Multi-GPU Support for DirectX 12 Developers

post #1 of 90
Thread Starter 
Quote:
DirectX 12 gives developers the option of using more than one GPU on a single system, even if those cards are different models and offer different performance. However, Microsoft has never really pushed this ability beyond a concept, and at the moment if developers want to pool GPUs they have to do all the heavy lifting and code everything.
Quote:
Microsoft has finally decided to offer a pathway for easier coding to achieve more than one card working on a system. Removing some of the difficulties, developers can now use minimal coding to achieve multi-GPU systems.

Awesome! It's going to be good to see this in use!

Sooooo. First thing I didnt read the article. Got to hit the hay soon but is this a direct win for the GTX1000 series or this just a elaboration of what we already were told dx12 would do in using multiple GPUs from different camps, makes and models and such.

Making it easier could help make this more common than it is now. But, I won't hold my breath. Multi-GPU support across different models could have a negative impact on performance, I am interested to see what they will do.

I wouldn't run a multi GPU config across multiple architectures, let alone multiple manufacturers. Each architecture has its strengths and weaknesses and it just doesn't sound like it would mesh up well when the two cards are trying to cooperate through SFR or AFR.

Im getting mixed signals here. Nivdia is limiting sli and MS is trying to push better support for it?

Whats going on?

Obviously you haven't been following benchmarks showing that there is a tangible gain when using AMD as primary and Nvidia as secondary video card.

Nvidia are hampering progress (oh, the shock!) while M$py are in a desperate struggle to ensure Vulkan (pushed by Steam among others) doesn't get the upper hand and make them irrelevant to gamers.

Ah, so the usual false promises then.

Right, AotS showed the usual false promises :rolleyes:

 

The only false promises we have seen so far have been from Nvidia claiming their hardware supports DX12 (not going to get into M$py and their spying).

I never get the argument of someone basically saying options are bad. There are a lot of things that "doesn't sound like it would mesh up well" that work just fine. That's why we have professional engineers working on these problems lol

This can be a benefit in certain situations where you have a card already and you find a crazy steal of a deal on EBay or Microcenter for a used card whether up a generation or down a generation.

I know a lot of peeps that don't like buying same generation cards by different manufacturers because they have some type of OCD of different cards not looking the same in your rig again that's a preference. I am not afflicted by that type of OCD so I would very much welcome this to the addition of long list of features that I am not forced to use. biggrin.gif

Again no one is forcing you to use these options they aren't mandated and won't affect you if you chose not to use it. thumb.gif
