Vega Crossfire ?

What's the story with Vega crossfire? I've seen footnotes in reviews that it isn't supported, but I've also seen benches of Vega FE working and scaling reasonably well in crossfire.

A cursory Google search brings up a lot of stories that AMD are distancing themselves from it and not really pushing it in their marketing, but that's a very different thing to it not working at all. Is there an official line on it? Has Kaap bought 4 yet?

Vega 56 in crossfire could be a fairly tempting upgrade path for those of us already tackling crossfire setups.
 
It's not officially supported, still works but not as well as it could, not worth the cost. SLI and crossfire took a back burner years ago anyway.
 
So it is still supposed to be coming?

I know well the pain of crossfire, but I have a rig with a 295-x2 and freesync monitor, which seems to at least trade blows quite well with a single Vega where Crossfire works. I really want to upgrade, but I don't want to pay silly money to move sideways.

I also quite like the game of trying to tame the heat of multiple GPUs :)
 
I personally wouldn't go crossfire.
One card for me yesterday at stock volts was hitting high 500s wattage.
AMD said supporting it less going forward, I thought it needed more support.

It needs support from devs too, a CrossFire profile can only do so much.

Yeah I'm not hating on AMD, but looks like less support from AMD and dev support is patchy.

Microsoft are the villains with DX12 and its rotten mGPU support.

If something is difficult to use it costs the devs money and they will avoid it.

Devs have to code for it. DX12 MGPU places full control to the developer, it means that we can't create a CrossFire profile for the game to enable MGPU.

If you look at a lot of the DX12 games we're involved in, we encourage the use of MGPU wherever possible. Sniper Elite V4 for example to name but one.
 
I'm sure I read somewhere that AMD wasn't bothering with Crossfire anymore. You can't blame them really, as it's been a bit of a dumpster fire. Even nVidia have issues with SLI.

I don't know where you read that, but it's false.

Raja's beyond crossfire speech where he is talking about a grassroots campaign to push the use of explicit multi adaptor and moving on towards other approaches in future architectures.
