is this legit?

hi guys can i ask if directx 12 is really stacking vram in sli or crossfire because i have gtx 970 maybe this is the solution..

We have heard the rumor as well, but DX12 is not out and they haven't made an official statement on it (I think), so we're not sure

[Will Barnard]

From what I've heard, yes.

[Tim Drake]

Unofficial? Yes

Official? No yet

i hope this is true because i have gtx 970

But you'll need a second card anyway, so you could always just sell that and get a 980

oook? lol

ill go SLI if this true..

basically instead of both cards producing the same image at the same time they will stager, so card 1 will render odd frames and card2 even frames. so they're working independently to produce the same image. 

 

but I'm not sure if that would mean the gap between crossfire/sli and single card performance will get closer.. as technically each card is doing the job of 1 card.

I am in the same boat. I have a 970. I am super happy if vram stacks in dx12 in sli, if not then would want to sell and get a 390x if rumors are true about that card (could care less about name on card just what they can do). The waiting game continues

[ManWithBeard1990]

Well realistically it will in multiGPU but not in SLI the way it works right now. Basically the developer chooses what card he uses for which independent task such that one card needing something on the other one's VRAM rarely happens (because that's why VRAM didn't double: all data was duplicated). TBH I think you can do that with DirectX already, but not with OpenGL (Vulkan will fix that).

[MeDownYou]

It is rumored that you won't need compatible gpu's to sli/xfire too. 

 

aka you could sli a 970 with a 980 if you wanted.

SLI and CrossFire already do that. That's not what this is. Think of it more like one card rendering reflections and shadow maps, and the other one the whole scene using that information.

Or one card draws everything with one set of textures and the other another set. Possibilities galore.

There's obviously performance to be had if it gets implemented and works well, but that's looking into the murky crystal ball and telling fortunes of futures.

 

The long and short is that we'll know when it hits the bench and gets tested, but until then it's just anonymous tips and speculation.

[InTechsicated]

There is no freaking way nvidia will allow this to happen. Even if dx12 does stack ram, I seriously doubt they would ever allow us to take advantage of it. They aren't the type of company to permit future sales of their admittedly good gpus being cannabalized.
