OK people, its official. DirectX 12 can support multi GPU and/or different brand GPUs working together. This is really exciting and makes me want ME:A to utilize this technology. For those of you who are unaware of what crossfire and SLI is, its basically where you can pair two (or more) of the exact same graphics cards to increase performance by near double what one alone can do in some situations. With the new directx 12 low level API this means that not only can you do two of the exact same card, but you can essentially mix and match different GPUs. This is really big news. I sincerely hope ME:A decides to be a pioneer for this technology and allow directx 12 as a viable API for GPUs to implement all the shiny newness that comes with this API. I am unaware if Vulkan is able to do the same, but this is just another reason why I so want ME:A to implement directx 12.

Sure. just remember that DX12  market is the XB1 console and those PCs with Windows 10. Also, multi-GPU configurations (ie: nvidia+nvidia or amd+amd or nvidia+amd) is a PC platform only configuration + Win10.

 

I wonder if Micro$oft paid EA to do the DX12 support.
 

[Drakoriz]

T.T i know i will be end updating to Win 10 if ME A is a DIrectX 12 game (i doubt it since Win 10 isnt the big success Mircrosoft hope for).

 

But i know if isnt this year next one i will end getting Win 10 bc there is no reason for game to keep using DirectX 11.

[Urizen]

I suppose I could ask what proof you have that it is not so.

operation system. DX12 only works on Windows 10. DX12, in reality, is just a more efficient DX11 and nothing more. However, the cost of making the jump would be forcing all PC

 

 

This is complete fabrication.

[Revan Reborn]

MEA can be a DX12 game and yet still support DX11. I already listed Crysis as a game that utilized two APIs, DX9 and DX10, the latter of which was only available on Vista. And then there was Assasins Creed, which supported both DX9 and DX10.1. And both games were in Development long before Vista was even released. DX SDKs are released long before a Version hits the market. That has multiple benefits, one is getting devs accustomed to the new API, another is that when the new DX version is released, there are already games in production that can utilize the new API and last, devs can give feedback on bugs and improvements. So far you have said nothing, that excludes the possibility of DX12 in MEA. I agree with you however on MultiGPU support. It´s far from being mainstream as the OP wants us to believe.

I'm quite aware that games that have released can utilize multiple APIs. The best and most recent example would be GTA V, which utilizes DX9, DX10, and DX11. The difference, as I already articulated, is that DX12 is Windows 10 only. Perhaps BioWare will support MEA on Windows 7, 8.1 with DX11 and Windows 10 with DX12, but there are so few DX12 games to start I just don't see it happening. As far as the games I have seen running DX12, they only offer DX12 and no previous API, so it really is the call of the developer and how much they want to support the game on different operating systems. Again, I'm just skeptical MEA will utilize DX12 at all considering this game has been in development since 2013. Maybe it will, but I'm not counting on it.

 

SLI/Crossfire is far from mainstream and I'm not sure it ever will be. Honestly, there is no reason to run two GPUs. It's overkill. If you have a single GTX970 or above, you have more than enough graphical power to run any current game on max settings. There just simply isn't a large enough market for SLI/Crossfire which is why I'm skeptical it will ever catch on. It's just not affordable for many PC gamers and they aren't going to shell out the extra money and hope a developer actually incorporates the feature in their game.

 

You are correct. I assume the risk when I use SLI. I haven't had many problems so far though.

 

Why do you think ME:A can't support both DX11 and DX12? I can use DX11 on my windows 10 PC. I don't understand where this is coming from. DX 12 is a lower level API, which means that its closer to the hardware and less like software as what it controls for the GPU/CPU. Why do you say ME:A is designed for DX11? Where are you getting that from?

 

Here are a list of games that support DX12 so far. Ashes of Singularity has been the talk of the town lately.

 

Now I understand the reason why you are so against SLI/crossfire and that is because you got burnt. I'm sorry to hear that, but I have not had the same experience. I contest that devs need to have SLI/crossfire in mind from the beginning for it to be a decent solution for gaming at High Res with High graphics settings.

As I stated above, there are not very many DX12 games. Most of your list was comprised of games that are getting DX12 patches. The few that I'm consciously aware of: Quantum Break, Fable: Legends, Gears of War: Ultimate Edition, will offer only DX12 and nothing else. Assuming MEA were to be DX12 compatible, we aren't sure whether BioWare would offer DX11. Again, this game has been in development since 2013, so the likelihood it is using DX11 and not DX12, which is brand new, is pretty high.

 

No. You are letting your own bias cloud your judgment. I am telling you from the perspective of a realist. SLI/Crossfire is not mainstream and it may never be. It's just too expensive for most PC gamers and there just aren't enough benefits for the investment. On top of the fact that most developers don't support it and it's a wasted investment. I merely was giving you my own personal experience why SLI/Crossfire isn't as "grand" as you are making it out to be. It's far from perfect, and the longer the feature is a niche, the longer it will continue to be irrelevant and underused.

Q. What is the 'official source' for this information?  Do you have an authoritative article to link to?

 

I googled "directx 12 mixed gpu" and found two postings with no authoritative confirmation. This wccftech.com article is partially based on an unconfirmed (and useless) posting on LinusTechTips. Nothing is confirmed about DX12 having anything to do with heterogeneous multi-GPU configurations. It's not even mentioned by any credible source I can find.

 

Geforce.com's FAQ on the limitations and specs of matched GPUs mentions that a 'few' identical GPUs can be mixed with certified GCs from different GC manufacturers (Asus, MSI, Geforce, EVGA, Gigabyte, etc.). NOT even GPUs within the same family can be paired (Can't pair a GTX 960 with a GTX980); the Maxwell GPU microarchitecture isn't designed for this, regardless of a Windows DX API. If the 900-series Maxwell family of GPUs and corresponding drivers could do this with Win 10 and DX 12, don't you think Nvidia/AMD would be shouting this from the mountains? That kind of breakthrough only accomplishes one thing: to allow gamers to stop buying newer graphics cards and instead buy reduced-priced GCs of equal or lesser GPU models - and probably invest in an older MOBO that supports multi-GPU cards with this option. I can't find any evidence of this. It's just not part of Nvidia's and AMD's GPU roadmaps. They'd be slicing their own throats - literally.

 

Then there's this wikipedia note re: Maxwell 900 series issues with DX 12. And Pascal is going in a different direction entirely, according the ExtremeTech's notes from Nvidia's CEO Jen-Hsun Huang presentation in March 1015. Even if different GPUs could be mixed on the same MOBO in a SLI or Crossfire config., a faster GC would have to slow down to the capabilities of the slower GPU - so what's the point of buying a faster and more expensive GC, if you can buy an identical GC for significantly less money than it's original MSRP? 

 

Given the decreasing costs of older GCs and MOBOs, I suppose you could buy an older multi-GPU MOBO and an older matched GPU for less money than their orig MSRP, but that's putting good money after bad as they'd all be underpowered for newer games. Makes no sense at all.

 

UGC - please don't take my comments personally. I'm just not finding any evidence for what you are saying is "official", plus, it makes no financial sense and has no forward-compatibility gains at all.

This does not accurately depict the "trend" of SLI/CF use. You have 2 polls that were taken a roughly the same time with a wide enough difference for us to not even know what the margin of error is and a poll that was conducted in 2010.

 

The question still is "will DX12 increase Multi GPU use?"

I think he was addressing the whole "DX12 is just a wee bit different than DX12" bit. While AoS doesn't really show this diff with Nvidia that is prolly due to asynchronous shading.

[pdusen]

There's absolutely no technical reason why that would be a problem.

[Revan Reborn]

It's not a technical issue. It's a priority issue. MEA is already coming to X1 and PS4. I'm not sure if BioWare is going to make sure it's compatible on a wide variety of DX APIs. Honestly, the only API I expect it will likely be compatible with is DX11, as that is what most games currently are releasing with on PC. Maybe it will be DX12, but the video in the OP, itself, states Frostbite 3 only recently incorporated DX12. They also didn't give a time table on what would be the first game to use it, so it may not even be this year. We just don't know enough.

BW already has to optimize for DX12 with XBone. Also it does not take the entirety of the development time to be able to utilize a specific API and even if it did, some companies have already know about DX12 for years.

Oh I agree with that.  I'm talking about the part that was bolded and italicized. 

 

 

DX12, in reality, is just a more efficient DX11 and nothing more.

Which is completely a fabrication.  It includes things such as pulled from straight from Mantle and Vulkan.  I mean, literally pulled right out of them.  Add to this, after DX11 came out, MS said that they were done with DX.  You don't honestly believe that if another company (*cough*AMD*cough*) hadn't have come along and show them the error of their ways, that they would have restarted the DX program?

[Revan Reborn]

This is speculation and nothing more. Nowhere does it say MEA will be DX12 on Xbox One. All we know is that developers have the discretion of using the DX12 API should they choose. You seem to forget DX12 is a brand new API. There are barely any games out there that actually support the feature. You are letting your wishful thinking for MEA running on DX12, as well as having SLI/Crossfire support, dominate your reasoning rather than actually sticking to the cold, hard facts. I only fear you will be terribly disappointed by the truth.

[goishen]

This is also complete fabrication.  DX is, and as far back as I can remember, always has been backwards compatible.

[prosthetic soul]

The whole video was showing video footage of ME:A and they were talking about how directx 12 is going to be supported on XBox one and PS4 isn't affected because it runs on Open GL -so there is no drawback for running the game on directx 12 besides the fact that some people don't want to upgrade to windows 10 which would hurt the sales only ever so slightly.

If Bioware has any, ANY semblance of concern for what remains of their reputation, they should really....really, really, really, not do that.  Please Bioware, I am telling you this right now, directly.  If there is a staff member reading this post right now, for the love of humanity do not let your company do this.  Write in to the person who is in charge of your headquarters and beg them not to do this. 

 

The only outcome you will get out of making Mass Effect Andromeda exclusive to Windows 10 is more unnecessary ire and a worse reputation.  I am telling you guys this out of legitimate concern because I am not planning to support Andromeda either way.  When you're in a hole, YOU STOP DIGGING.

they wont dont worrie. Only Microsoft game are exclusive to Windows 10 at the moment but M$ is concern how ppl arent making the swith to 10 as it was predict to happen. SO not only they forcing the upgrade now also they are releasing exclusive win 10 games that only work wiht Dx12. Like Quantum Break and Probabbly Gear of War 4.

 

Bioware/Bethesda/Blizzard/Ubisoft/CDproyect will not cut their sells in anyway to market Win 10 or Directx 12 like Microsoft is doing,  bc they dont win anything doing that.

 

There is 0 reason to make ME A DirectX 12 exclusive when WIn 10 only represent the 11% of the market right now.

XBone still run games that are optimize for Dx11.

 

The game dont need to be optimize for Dx12 to be able to work on XBone. If is optimize is bc it was mean to use the full power of Dx12. If not the game will work normally.

[Revan Reborn]

I suppose BW could optimize for DX11 for XBone, but why?

Perhaps because this game has had a workable build since 2013 and DX12 games are only now just beginning to occur? Besides Microsoft exclusives - Quantum Break, Fable Legends, and Gears of War: Ultimate Edition - there are not any games coming to X1 that I'm aware of taking advantage of DX12. Microsoft is making a push for DX12 because they have an interest in other developers making the move. That doesn't mean other developers are jumping in as quickly, however. Based on the video you linked, it's not clear if any of the Frostbite 3 games coming out this year will have DX12 support. All we know is that DICE's engine development department is now working with DX12.

I'm honestly surprised how many people are still using XP. That said, it looks like windows 10 is the second most popular OS currently. If you moved half of the Win 7 crowd to Win10 then Win 10 would be a majority. I still don't get why people don't make the free upgrade. If its a matter of privacy, what exactly are people doing that they need to hide exactly?
