I dunno, I bet they will lock it out at the hardware level then. If it is possible to do it, they will do it.

Does Nvidia own the DX12 rights or own Microsofts windows platform NO so essentially it is Microsofts bag and they decide if the cat gets to play in said bag or as I termed it before Windows is Microsofts playground / school if Nvidia or AMD don't play well they can essentially expel them or cut them off and also sue them because of the legally binding agreement they signed when they partnered with Microsoft on Microsofts project DX12 because it isn't Nvidia or AMD's project or OS. So Microsoft can give them the shaft anytime they choose they can go full hilt no lube or take it easy and atleast supply lube but it all depends on Microsoft not AMD / Nvidias choice only Microsoft get say in this matter.


Do Nvidia or AMD have theyre own OS that is such a large ecosystem NO so essentially they will be at mercy of Microsoft again Microsoft will hold the keys not AMD / Nvidia and DX12 is Microsofts baby and Microsoft already said 100% positive the multi GPU cross vendor / manufacturer functionality is a core part of DX12. So again if Nvidia or AMD try to do anything to combat this they got Microsoft to answer to and Microsoft can essentially leave either Nvidia or AMD screwed in every sense of the word because the core platform for gaming is windows and Nvidia / AMD know this and who is the largest and most powerfull software company on the planet Microsoft so essentially Microsoft could easily ruin either companies life at anytime if they so chose.

So essentially AMD / Nvidia answer to Microsoft at end of the day and they know if they upset Microsoft they are in trouble in so many ways in essence Microsoft will have control in the windows platform with DX12.

I think you're wrong on this aspect. The Windows VGA driver isn't sufficient for 3D (hell, it doesn't even support Aero IIRC). There will still need to be AMD and Nvidia drivers installed in order for the OS to effectively communicate with the hardware (video card) to its fullest capabilities. Would be nice if Kollock could weigh in since now you have me wondering.

Don't generalise, it's not NVIDIA fans. It's just particular types that nod incessantly within their cliche whilst being overly negative about a corporation that spans globally and doesn't really have a face.

Don't worry I messaged Kollock with direct links to my posts and told him what I have heard and why this is my understanding of the situation.

It just isn't going to happen. The market is far too niche; dual identical GPU systems are rare enough as it is.

It's an interesting tech demo, that's for sure, but that's all it is.

You're overlooking the iGPUs. Mixing these with dGPUs would be mainstream.

Hopefully he can chime in as I just don't see how it wouldn't require an AMD or Nvidia proprietary driver. They are the ones who make the hardware and would know how it could be utilized to its fullest potential so I just don't see Microsoft putting in the resources themselves (which would most likely result in sub-optimal performance of the video cards for gaming). It's the same as with most devices; Microsoft provides standard drivers which are stripped of features and require the manufacturer's drivers for the best compatibility/performance.
