amd and nvidia in 1 pc

Yea that's cool as hell! Should have made the title of the thread more exciting. ;)
 
It's nice....but it's slower than AFR provided by the professionals (AMD, Nvidia)

Still, has potential for more. But I'll be much more interested in the results if the released game, when we have fully-optimized drivers.
 
It's going to be great for people with Intel and AMD CPUs that have an iGPU in them. It might put you over the hump so that you can enable a few more graphics settings.

We'll see. This is simple AFR, and the scaling is unexciting. But it does work, so at least we have that one confirmed :D
 
If this takes off, I wonder if it would be possible/practical to make a dual gpu card, with a gpu from each team. Ignoring cost, and likely licensing/marketing issues with a cross-branded card, it might not be the worst idea considering it could offer fall-back single gpu compatibility modes for those titles that either don't work well with mutli-gpu dx12, or have a strong brand preferance between nvidia/amd.

Likely, cost and other compromises would make the card impractical, but it would be interesting to see.

Or just add in some software to choose which GPU is #1 as it seems to matter in the testing. :)
 
LoL... Since people said it would never happen, well it did and a lot sooner than anyone would've thought!

These Oxide guys are on the ball and on the bleeding edge of graphics developement.

Kudos to them!

(It also probably helps a lot they are a small company and not stuck like DICE is with EA)
 
has to be implemented by the dev I think

I wonder if the GPU companies want you to slap 2 - 3 of your old GPUs together and get better perf than their flagship without the problems of SLI/CF.

Pretty sure they dont want that.
Pretty sure this will never be a reailty then, devs will have no incentive :(

I hope it does though, in the next 5 years maybe.

This could change the upgrade scene forever, in the long term.

You wouldn't be able to tell from the gameplay footage, which seems more like an indie supreme commander knockoff with graphics from 2005

AMD already permits Crossfire in different configurations and even different generations as long as the GPU is the same type.

Current graphics are just placeholders to work with I believe. Nothing final, which usually comes in later in project developement.

idk..to me its very interesting....quite a performance increase using both cards. Cool as hell!!:)

Not to sure but was this not already possible under OpenCL ?
You can use OpenCL to spread tasks across multiple GPUs, but it's not well suited for rendering games like D3D 12 is. It could be used for other tasks like physics, but there hasn't been much interest in doing that so far.
 
does anyone recall lucid hydra? I wonder how this would compare to that solution ?

Lucid Virtu MVP ran very good for me with the 3770K iGPU + any other dGPU used mostly for Virtual Vsync and worked good before I got the 120hz panel, sadly it doesn't work in W10 so i can't test again with more recent GPUs.
 
Now this would be a dilemma, imagine if PRIME was gifted a high end pc with a 980ti and a fury x working in tandem for dx12 games. Do you think he'd take the increased performance or purge his system and cut out the amd card?

I'm thinking the latter.

I would do to buy another Nvidia card and be able to enjoy Multi GPU setup in other games and not only DX12 games.
 
no

The message you have entered is too short. Please lengthen your message to at least 3 characters.

I thought that the "current" driver would allow this under OpenCL spread tasks to whichever compute form was available rather then stuck to a single gpu by default..
 
Well, I imagine PhysX would still be disabled due to Nvidia's Vendor ID check. And I certainly wouldn't be surprised if Nvidia decides to sabotage this explicit multi-GPU function in a future driver update because SLI mode wouldn't be "certified" when used in conjunction with an AMD card.

Sure they will piss all over Microsoft just because that is very good way of doing business ...

You can do anything you want in OpenCL, including writing a complete reali-time 3D rendering engine with multi-GPU support. However it doesn't have any built-in framework for such a thing, so you would have to write it all from scratch, which would be much harder than using D3D. And it's designed for compute, not graphics, so you would miss out on a lot of harware acceleration.

I was not talking about the DX12 feature I'm talking about driver support for accessing multiple GPU from different vendors in one machine with OpenCL.

Yes, you can send tasks to any combination of GPUs regardless of vendor, as long as they support OpenCL. You can even distribute a workload over GPUs and CPUs at the same time.

Nvidia and Microsoft have never had a good relationship. Remember the original Xbox lawsuit?

I could easily see Nvidia purposely disabling explicit multi-GPU with any Nvidia cards if only because motherboard manufacturers wouldn't need to pay Nvidia for SLI "certification" anymore.
 
Are the DX12 functions used in mixed GPU setups core parts of DX12 functionality? Meaning is access to these functions required for DX12 certification?

There is no real black magic, special functions, or whatever voodoo behind it. It should be just another adapter in the grand scheme of things that you do whatever with. That's the point of explicit multi-GPU.

It is on your plate to ensure that they actually work together in a meaningful way, though. Nothing dictates that you must use AFR, or SFR, or even do graphics work at all on the second card... or third card, or whatever weird scheme you concoct.
