Vulkan multi-GPU support will require Windows 10

[HEXUS]

As it needs a system with WDDM 2.0, which Windows 7 and Windows 8.1 lack.

Queue the groans from gamers who decided to stay on Windows 7

No mention on cross-vendor support though...

Linked display adapter mode seems a bit of a dead end what with multi display adapter mode becoming a thing.

Linked display adapter mode seems a bit of a dead end what with multi display adapter mode becoming a thing.

Is it though? In a plausible future where 4k 24-32 inch displays with 144HZ are common, I'd much rather one of those than a plethora of smaller screens all individually connected to different GPUs, from an array. Especially if I could power it with two GPUs of different models. (different VENDORS being a bonus, really)

[Corky34]

Not sure where you got the plethora of smaller screens all individually connected to different GPUs from as multi display adapter mode isn't that (afaik), it's using multiple display adapter (different vendors and models) linked to a single display, as in it's the same as linked display adapter mode (SLI) but doesn't force you to use the same GPU's.

[Ozaron]

Excuse me, my bad. How does the mode work? I mean, there's still very little in the way of support for cross vendor GPUs, so I can't imagine how using both AMD and NVidia (or something more funky) would happen. Always assumed people referencing this mode meant they had two(+) GPUs and each one connected to a different display (or displays) for Eyefinity, etc.

Well GamerNexus carried out some testing under DX12 and although they only tested AotS it seems using GPU's from two different vendors improve things, i guess it's the best of both worlds effect.

If you know the strengths and weaknesses of the GPUs, I can imagine that you could farm certain functions to one card or the other, making a more efficient mGPU setup from different models/vendors.

The question are: Will Vulkan support it and can developers handle the power they are being handed...

[nobodyspecial]

That's OK, I've been building PC's for 25yrs and have never had the need to add a 2nd gpu's heat to my world. Heck, even as a PC business owner for near a decade I never sold ANY dual card systems for gamers (only 2 to workstations). Almost nobody cares...LOL. Win7 until 2020 here

[bergamot]

That's me buggered then- I was cash strapped when I built this rig- couldn't afford a discrete GPU, so I bought an AMD A10 processor (seemed best 'bang for bucks at the time) and later added a 4gb nVidia GTX960- that could be swapped out to a newer build when I upgrade my mobo and processor. And I'm still on Windows 7.

sli or crossfire ... who cares really? only the rich will buy them and run them and pc development really needs a finger pointing and everyone sahouting at once "thats too expensive!" for anything to change.

Good on AMD tho for the ryzen ... almost the same performance as intel at half the price, lets hope they do the same to nvidia, it's the only way some people will stop using consoles and become pc lovers.

Historically, you could get better performance for cheaper using dual GPU at certain points.

And what do you want changed? Ban 4K, 120HZ+ etc?

So the original announcement was fake news(tm)

I wonder if it was leaked by Microsoft in their "Windows 10 world domination" bid?

I wouldn't be surprised. The desperation is dripping off them.
