is the directx12 will have cross-sli feature?

is the directx12 will have cross-sli feature?
AMD GPU + NVIDIA GPU To Work Together for example 4gb nvidia card + 4gb amd card to work together with 8gb vram
i heard rumors  that the directx12 will make the gpus work together at the same time with alot of vram
please help me know if its real
Thank You

With the same GPUs, not different GPUs I guess. It just stacks VRAM?

No

DX12 ALLOWS it, that does not mean it will happen

neither AMD, nvidia, or game developers will make it happen together

so no you will not be able to have AMD and nvidia GPUs in the same system, and you will not be able to stack vram

No. Even if it does support it, there's no way Nvidia (and probably AMD) will support it.

Yeah its real, but does things are all optional that would need to be implemented by the developer so don't expect every pc port using directx 12 to have it. i only see really big fans of new pc features  using this like Crytek.

No, DirectX 12 will not make that possible.

What part of the question are you trying to answer?

It is possible but it is unlikely to happen. Nvidia wouldn't allow it. AMD might as they are more lenient about it but it wouldn't matter since Nvidia wouldn't allow it. The stacked VRAM is up to developers to make it happen, hopefully AMD & Nvidia will push stacked VRAM into games

Oh yeah remember that AMD crossfire new gpus anyways that support direct X 12.0 don't use ribbons that link through the pci express slot so even if the api allowed it their are now physical limitations.

There's already a company that showed them using an amd apu with a 290X, so possible, absolutely, but something tells me that nvidia won't allow it.

The whole thing? Using a multi-GPU solution mixing NVIDIA and AMD cards. DirectX 12 will not make that possible. I didn't realize there were more questions than that.

Hell, NVIDIA won't even let you mix other NVIDIA cards, let alone AMD cards

Yeah he also asked about Vram stacking when using a crossfire/sli configuration, directx 12 will make that possible.

Well, you CAN get an AMD and an Nvidia working in the same system. Multiple card setups existed before SLI and Crossfire existed. You can't get then into a SLI or Crossfire configuration, though. The only way you will see them working TOGETHER in SLI/Crossfire is if Nvidia started using AMD chips or AMD started using Nvidia chips. I wouldn't expect that to happen any time in this milennium.

not anymore

nvidia changed their drivers to completely disable is there is any AMD card or software installed on the same system

you used to be able to put both graphics cards in a system and change between them, but thats changed

afaik this is already possible in games like civ beyond earth. its all in developers hands, they have claimed dual vga cards will be able to truely act as one with dx12.

Ehhhh, that is with Mantle using two similar cards to do split frame rendering instead of the usual alternate frame rendering found in Crossfire and SLI.

 

In theory "Cross-SLI" is possible, but it requires a lot of effort on the part of the software developer to micro manage communications between cards with different capabilities. It just ain't gonna happen the way people think it will.
