AMD + Nvidia = No features lost?

[Silverfields]

IF one were to put a 980ti and a Fury X in the same system, how would one switch between them? Would I have to reboot each time I wanted to switch? Or would it let me decide in windows? I'm currently planning out my first PC build, and each side has features that I want to take advantage of, but obviously I can't make them work together unless I'm playing a game using DX12. Money isn't an issue, as I've been saving for this build for quite a few years.

Thanks in advance for the help.

i think linus did a video on this

The one I found didn't have any instructions on how to actually switch cards, plus it was using 780Ti's and 290's

980ti obviously offers CUDA, but, besides HBM, why do you want the Fury X?

 

I'm not saying it is a bad card, but if it is HBM, you can wait for Pascal and SLI those.

AMD has better OpenCL support last I checked, and it has better performance(last I checked) in DX12.

[i_build_nanosuits]

i have no idea as i've never done it before but i respect the idea...

but what about monitors?! a Freesync one and a Gsync one?!

true enough, but either way I would wait for Pascal, it is only a few weeks away.

It doesn't matter what cards he was using, the instruction are still the same.

And he did state that all you would have to do is switch the input on the primary display. Thus meaning you have two video cable from your monitor to each of the GPU.

but this is old news, DX12 is different because its running both gpu at the same time

but only one gpu as the main driver

so i suppose if the game supports mantle and physx, you can use both (if the game supports it)

but if your monitor supports free sync, you probably must use the amd card as the main card

 

these are unconfirmed because DX12 is pretty much still foggy

If I were to have both a G-Sync and a Free-sync monitor plugged into a Fury X and a 980ti respectively, would I be able to have both on at the same time? If not, how would I switch between cards?

[SLAYR]

You could have a monitor hooked up to each and switch the main display in windows to the corresponding card so that the game launches using that card, but as from experience using amd and nvidia in a system somewhat like this there will be random crashes, abd general instabilities because the drivers do not like to work together well.

you probably can only run your games with either card as main driver but only one card as the main driver

Is there a way to have only one card running at once? For example, I'm playing a game using Nvidia's technologies, would I be able to disable the AMD card while gaming on the Nvidia one? That way I would have to deal with the drivers conflicting with each other.

Or would I just have to remove one of the cards from the system completely?

You can disable individual cards through windows but it is a pain to disable and reenable each time, but the drivers never stop functioning so you will always have that issue. Removing the card wont help the driver incompatability because they are software based. 

 

The easiest option to not have any issues is to pick a side that has the technologies that you want/like the most, there aren't too many differences between amd and nvidia technologies besides freesync/gsync ? , and stuff like shadowplay.

What kind of bugs would I have to expect? Computer crashes?

[Atmos]

okay, let me say this. 

Nvidia + AMD would mean no features lost, HOWEVER this isnt a new concept. People used to run AMD and Nvidia (Myself included) but Nvidia fucking decided they wanted to force people onto one companies ecosystem or the other, so they patched into geforce experience to terminate itself if it detected catalyst/crimson running. 

 

DX12 multigpu cross vender will NOT be a thing, regardless if devs implement it, nvidia will not allow it, period. Theres no debate about it, that's a fact.

So I should just pick the one that I need the most then? Kinda sad. I guess I'll just get whatever I need at the moment, and keep an eye on DX12.

Thanks for the information.

It's the same idea... Well it would sound like it's not a thing anymore. That's kind of dumb, oh well... 

But Why do you want the 980ti?

Yeah crashes, freezing in heavy gpu tasks, and i have had one of the cards flat out stop working altogether before. But i am also using an older nvidia driver with amd crimson, newer drivers might help, but I they wont support the gpu i have in my system.

 Yes that would be the only way to have your system be stable, i have no clue to how dx12 can affect the driver instabities, but just having one set of gpu drivers

makes everything a lot easier to deal with.

As of yet, only ashes of the singularity seems to support the technology of combining two graphics cards. This benchmark is from Anandtech, october 2015.

As you can see, the scaling is poor. Though this was about 5 months ago and the game has most likely seen significant changes since then.

dude, you have no idea. 

 

just stop.

just re-read my post, typo, meant to say nvidia wanted to force people into one eco or the other, not amd wanted to force people into one or the other.

 

And that's not a lie mate. Want to test it? With clever patches you can get geforce experience running at the same time as catalyst/crimson, but don't you dare try running any nvidia proprietary features like shadow play, cuda acceleration, or physx. You'll find those have all been neatly disabled by the hard code on the drivers themselves. You only have one group to thank for that... Nvidia, the greatest anti-competitive vendor on the market; because if you want to use both teams hardware, then you don't get to use their technology. What they do makes me more sick than what intel has done and is doing.
