3/4 way sli won't be enabled for GAMES

Can't see it myself.

Most games are developed on PS4 (occasionally Xbox One) and ported over. PS4 doesn't have multi GPU so engines won't be designed to take advantage.

DX11 has meant Nvidia's driver team have been heavily involved in SLI profiles.

With DX12 the onus is on the developer.

alright what if the consoles had mgpu, would that change anything ?
personally i believe ps4 neo will have 2way, and xbone scorpio will have 3way, it will be the same concept AMD has for Navi, rolled up ahead on consoles.
E3 is around the corner anyway, if the updated consoles turned out to be what i think, mgpu will take off on PC, and i strongly believe it will be the case.

The console's have APU's not discrete graphics cards.

The revised versions will not have multi GPUs as it would cost a fortune to make.

yes...thats why i said AMD's 2018 Navi architecture, which basicaly is multiple chips on an interposer, which is cheaper to make than having a chip of the same combined size.

Why? WHY? What is making you 'strongly believe' this will be the case? I dont get it.
 
The statement from NVidia on this issue seems rather contradictory, on one line they say they will support more than 2way and then they say they will but only in certain programmes. :confused:


NVIDIA statement:


With the GeForce 10-series we’re investing heavily in 2-way SLI with our new High Bandwidth bridge (which doubles the SLI bandwidth for faster, smoother gaming at ultra-high resolutions and refresh rates) and NVIDIA Game Ready Driver SLI profiles. To ensure the best possible gaming experience on our GeForce 10-series GPUs, we’re focusing our efforts on 2-way SLI only and will continue to include 2-way SLI profiles in our Game Ready Drivers.

DX12 and NVIDIA VR Works SLI technology also allows developers to directly implement and control multi-GPU support within their games. If a developer chooses to use these technologies then their game will not need SLI profiles Some developers may also decide to support more than 2 GPUs in their games. We continue to work with all developers creating games and VR applications that take advantage of 2 or more GPUs to make sure they’ll work great on GeForce 10-series GPUs.

For our overclocking community, our Game Ready Drivers will also include SLI profiles for 3- and 4-way configurations for specific OC applications only, including Fire Strike, Unigine and Catzilla.

Even if you are right (which I don't think you are :) ) the implementation would be entirely different with alterations to allow better communication and sharing between GPUs, similar to the way PS4 shares it's memory. It would have not impact on mGPU coding for PC which is constrained by the relatively low bandwidth.

Read the whole thing and not just the highlighted sections. Developers using DX12 may choose to use some of the inherent multi-GPU capabilities of the API, in which case it doesn't matter what Nvidia does or doesn't support as it's in the hands of the developers.

But anything using DX11 or whatever else that relies on Nvidia driver support for multi-GPU will never get >2-GPU SLI support apart from some benchmarking tools.

cool that AMD is working on a new interconnect.
yes ofc you will have overhead, thats something AMD can work on driver side to make it better, but the key point here is the Devs making the game on multi-gpu setup, where most of the bugs that plagued it like stutter would be gone.
besides the end game is Navi.

And that is my point, if it is completely out of NVidia hands then why do they state.

Some developers may also decide to support more than 2 GPUs in their games. We continue to work with all developers creating games and VR applications that take advantage of 2 or more GPUs to make sure they’ll work great on GeForce 10-series GPUs.

It makes no sense. :confused:

But again, multiple GPUs on the same interposer is not the same as current multi-GPU setups where each card has it's own memory and a low-bandwidth link to the other card.

Of course monitors dictate performance requirements. If the only screen available was 1920*1080@60Hz then we wouldn't need anything more than a 980ti.

Nonsense, games dictate performance requirements, even at 1080p games have been pushing performance requirements for the past decade regardless of resolution. Ofcourse higher resolutions need more capable hardware but its the games themselves not the monitors that push performance needs.
 
So from what im reading the only thing nVidia is saying is that they will only provide 2 way sli profiles through their drivers instead of 2,3 and 4 way. Nowhere do i read that they are actively blocking 3 and 4 way sli which to me would mean that you could in theory set up your own 3/4 way profile through inspector no?
