DirectX 12

[MrSushi]

Hello.

 

Is it true that new direct x will be able to combine VRAM of both GPUs in SLI? That would be really great. Will it solve my 2 GTX 970s VRAM issue somehow? Am going to get 7GB of VRAM?

 

Thank you for replying.

We'll see when we see. We don't exactly have a video of someone doing this yet.

no one knows, only rumors that we hear so there is no response to that

[Megahurt]

My guess is they'll just end up rendering half of the frame each instead of alternate frames, so each card only needs half of the data.

We know as much as you do, its rumored.

I'd love it if vram scaled, 4x4 980s man! 16gb vram!

8GB 290X in Crossfire? :3

Also, is a W9100 4-way crossfire compatible?  :lol:

If this is true then i will deffo be getting another gpu for mu system, just imagine the vapor x 8gb 290x in 4 way crossfire. 32gb of VRAM !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

It's just speculation up until now. But it could happen. Nobody knows.

Anything that wants to make use of two ore more GPUs in a non SLI/Crossfire way needs to be written/designed for it.

 

The new APIs like dx12 or glnext will just enable developers to get explicitly control of each GPU and there vram. Its up to them to make good use of that.

You still will get dx12 applications that make no use of it or like only use 20% of the second GPU.

Also there are many cases where you simply have to distribute lots of data on all GPU memory spaces to reach good parallel workload.

I think the mainstream use will come with support in big engines like the Unreal Engine.

Heyyo,

I read that today too... and... I dunno what Tomshardware is drinking but that smells like some really strong moonshine from Dawsonville!

It sounds WAYYYY too good to be true... no more multi-GPU limitations at all? no need of CrossFire or SLI-ready motherboards? WHAT KIND OF A WORLD DO WE LIVE IN!? lol... but seriously, I don't think DirectX 12 will be quite that ground-greaking.

Sure, it could fix the scaling issues with Split-Frame Rendering... it could fix Multi-threaded CPU optimizations by automatically scaling on its own.. but mixing GPU architecture and brands? Honestly it sounds like a dream. I'm excited for DirectX 12 and the optimizations it's slated to bring but I doubt it'll be as big of a leap in rendering technology as DirectX 8 was to DirectX 9.
