this is a dx12 issue
 
as jayz said on dx11 3-way and 4-way sli are not affected
 
developers wanted MORE control over SLi - hence MDA mode and LDA modes

 
Its the Software developers that wanted this so they are responsible for this - and so should they be- since SLi basically WAS a developer/OS optimization issue
now they have more control over methods and optimizations - Nvidia only has to provide 2 way optimized ...most users don't go beyond 2 cards(sli) and maybe physx.
 

Xavier Zepherious
most games don't scale well beyond 2 way anyways

Xavier Zepherious
furthermore CPU bottlenecks are the issues coming up - gpu tech is overwhelming cpu tech and are hitting bottle necks at the cpu
and it's only gonna get worse 
 
as jay said his 5960x was bottlenecked

Gonna just quote JayzTwoCents I think it sums up this whole situation well, "Nothing is more frustrating than people that pretend to know [insert alternative word for crap] that they really don't." NVIDIA has never really truly supported (or wanted to for that matter) SLI past dual cards as it's always been a thing that had much room for improvement. Gotta love all the reporters out there crying wolf since the first millisecond this was uttered.

So nvidia just adds dual sli fingers to their cards for no reason? Interesting.

 
Because tons of people wanted it, yes. Even Jay in his latest video said it was something they never wanted or technically recommended doing. Just because it's there doesn't mean they were all for its existence.

I'm sorry, and not trying to be an azz when I say this, but that makes absolutely no sense to me. They are the ones in complete control of it, from the initial design specs to the final product. If they didn't really want it, they didn't have to build it the way they did. It seems to me a bit of a cop out. "Weeeeelll, we Really don't want to do X, but because a significant enough number of our consumers demand it, we'll put it in, but we're not going to officially approve of it, or support it in any way. So take your toys, and shut up, and if you can't figure out a way to make it work for you, tough." Hmm. Interesting is an appropriate expression in this instance.

well i just watched the nvida vid on the 1080 and sli and they are being a big ****.  cut the bull out of all the fiance talk .   you can run 3 and 4 way sli but with old sli briges with the lower  bandwith or 2 cards with the new beige with the new doubles bandwith. so why not just make us all happy and build a new beige with the double bandwith  . even if you had to add a 3rd tab on the card to do it instead of the two that they come with. so like i said going to wate for the titan and 4/way and brige type that comes out before i buy , and if it's old brige then it's by to nv ida and i go amd..... i will have all the bell and wiles lol or i go where i can get them . see to me it are monny they want us to give them . so see we have the power we all just have to all say the same thing lol

Did you bother to watch any of the videos or read any explanation? NVIDIA clearly explains why they are only officially supporting 2 way SLI for pascal. You can do 6 way SLI if you want but it is up to the game game developers to support it. Assuming you need 2 fingers to support the HB they would have to add 6 more fingers for 4 way SLI. 
 
Nvidia is simply saying if game devs don't want to screw with doing the work for optimizing SLI they will handle if they follow their guidelines. At this time they don't feel there is enough of a performance gain over the 2 way SLI using the HB bridge. 
 
For anyone wanting them here are a few SLI benchmarks:

Everyone knows game devs could care less about 3x or 4x, for the most part. So we might as well kiss 3x or 4x good bye.

Just wanted to add .02 regarding title - really poorly crafted, I only clicked because of how confused it made me. "Nvidia will only officially support 2 card SLI Configurations". fify

Looks like you need to go tell nvidia to fix their control panel too. 

Seriously, your title is click bait. It should read, 'Nvidia to officially support 2-way SLI on GTX 1080'.

Once again Tom Petersen @ NVIDIA on PCPerspective live episode the other day said with a firmware update it will unlock 3-way and 4-way SLI for those that want it, and they will have the bridges for it. Those that use 3 way and 4 way SLI are the minority, but if you just have to have that 3rd or 4th card they are not going to stop you.
 
Here stop making it an issue it is not. From the Horses mouth.

The control panel isn't incorrect? lol. The control panel is showing two cards in 2-way sli yet it just says SLI. 

Indeed, because of course, it wouldn't need to say 2-way as that is the only possible SLI config with two GPU's. So, putting 2-way would be as redundant as your arguments. Whereas with 3 or more GPU's, additional configurations are possible. So the control panel is entirely correct and your usage is wrong as established by Nvidia.
