I thought DX12 changed SLi and Xfire ?

Over the years i have had many AMD cards but the nightmares people seem to have with crossfire has convinced me to never go crossfire. AMD must lose a lot of sales due to this!
I've been with AMD for a very long time, maybe 10 plus years, last Nvidia card I had was a 6800GT and from about 2012 I've been using a crossfire setup. Firstly it was 7950's, then middle of last year I went to a couple of 390's. In the past crossfire was flawless, such a good setup for the buck and on the whole trouble free. Then came the start of the problems, bad drivers, no profiles around November 2014 and for about 5 months things were particularly poor. Things did improve again but I feel these last few months have been very poor again. So much so that I've just about had it with AMD, and definitely with multi gpu setups. Next upgrade for me will more than likely be Nvidia, unless AMD do something good with DX12 and these cards that is.
The thing that seriously annoys me is the false advertising to crossfire and or sli. We get all these great motherboards that advertise crossfire and sli, we get plenty of dual gpus, we get endless spiel from the companies about great multi gpu support, yet games come along and they are nothing but unsupported POS now. If it's not one thing, it's something else, you now spend more time trying to find profiles that semi work and drivers that are working correctly than playing games. I feel I'm forever studying overlays these days scratching my head why my clocks are fluctuating, or why my 2nd card is sat at 300mhz doing naff all.
Overall it's now at a point where I'm pretty much ready to sell 2 390's with waterblocks and a Freesync screen because I'm fed up with the constant issues and faffing around.
It turns out it was the drivers. I've rolled back to 15.7.1 and everything's ok again now. It became unbearable in CS:GO last night, the flickering was every couple of seconds.
Tbh i would keep what you have or drop to one card. It appears to be the games as Sli users are also having issues. If it's not the games then both companies have dropped the ball at the same time.

TBH I really wish there was a seperate GPU forum for Crossfire/SLI.
It's very annoying when threads become cluttered with MGPU problems. Of course there are problems, less than 1% of PC gamers use MGPU. What developer in their right might will spend money to make it run properly?
Then average joe comes along and reads these threads, assumes there are widespread driver problems, hence the driver bashing begins.
AMD/NVIDIA drivers are rock solid for single cards, as they have been for many years.
Damned enthusiasts posting on an enthusiast's forum...
What is it with people with multi-GPUs and those that overclock!

It actually turns out that it wasn't the drivers after all. A couple of days ago it started black screening and flickering again with the catalyst drivers. I switched ports on the card and i've only had it happen once so far. I upgraded to the Crimson Hotfix drivers again and it's been ok so far.
After all this talk of cables, i've ordered a new DP cable to hopefully fix or rule it out.
It would be nice if the driver section had sub sections for Multi-GPU etc
Maybe we could just start separate threads for Nvidia SLI (drivers?) and AMD Crossfire (drivers?), not sure if the mods would be ok with that?
Maybe also threads for those with overclocks? Although doing overclock thread for single and multi GPU for both AMD and Nvidia might get silly.

Overclocks don't need their own threads, since overclocking is very much supported/problem free on AMD as well as NVIDIA.
Would be great tbh.
Seeing as it sounds like it's a bit like what Far cry 4 was to Far cry 3, ie: a re skinned new storyline build with only a few significant changes on basically the same base I'd gues that if there's a profile for Tomb Raider there should be for this.50-50, there either will be a profile, or not.![]()
People whine about no crossfire profile but they forget about optimze 1x1 and AFR Friendly. These options work 3 times out of 5.
I am on 15.6 with no crossfire profile for Metal Gear Solid: Phantom Pain and with optimize 1x1 it works.
