AMD did not mention CrossFire once during their RX Vega launch

Is AMD dialling down their support for Multi-GPU?

Well it makes sense. We need better software support from MS and Vulkan to get it going much easier and have it be more simple. It's not entirely necessary to have so it's hard to expect Devs go out of there way to get it working.

If they see in there statistics from drivers that only 1% is using Cfire, honestly then put that money and time into getting better faster drivers out for single solutions

DX12 ended up being disappointing, largely. Some games benefited from it, but nothing to write home about.

1) Very few games take full advantage of the new low level tools, party because it isn't necessary since:

2) The main benefit of Dx12 is lower CPU overhead, and that hardly matters when we could push 100% GPU usage with Dx11 and rather poor multithreading.

I've so far only seen 1 instance where DX12 actually made an improvement, The Division, I went from 80FPS average max settings 1440P to 100FPS average, Any other game I've seen negative results.

DX12 has not been used as we were promised it would. We were promised multi threading and higher CPU loads. So far I don't even think there's been a ground up DX12 game to speak of that uses all of its features properly.

Well looz has a good point as to why. I feel people forget (mostly gamers) what DX12 is really meant for. It's really meant for the CPU and most games aren't CPU bound. Games like TW/CoH/Civ series are CPU bound. And ironically they are RTS games. Which makes sense. As historically RTS genre has pushed the industry forward in regards to the latest technology.

Civ is turned based, not RTS. How dare you.

It seems both GPU makers are abandoning multi GPU setups a bit early, especially for us 4K guys. These clowns can't make a single GPU that will shred 4K, so it makes me wonder why they'd abandon it now.

Eh 4x games. Same thing!^_^

They abandoned it because Devs basically all virtually have

I'm quite sure that at least in case of Civ the CPU load is due to game logic and not graphics, and upgrading your processor usually just makes the turns quicker. So even there the graphics api isn't that important.

I am 95% sure that Cuv 5/6 and BE use the CPU for game logic and geometry. So CPU throughput it pretty important in these games, hence again my reasoning earlier about RTS/4x games usually being the ones that need CPU power the most

I am happy that both AMD and Nvidia are moving away from CrossFire/SLI. The only thing that i like with dual GPU is that it looks epic. It makes sense only if your 1080 Ti can't handle your monitor setup. And even then you get micro stuttering, and scaling is horrible. It just isn't worth.

What i want to see is Threadripper based GPU. Oh yeah. Multiple GPU cores on a single die.

This probably means we won't see a dual Vega card. I think thats why the current Pro-Duo is fully under the Radeon Pro branding now and not the hybrid card the Fiji Pro Duo was.

Point being that even there Dx12 and Vulkan aren't that significant, when bulk of the CPU load is taken by logic.

Good point. Maybe DX12 support will improve now that Ryzen is out.

I think Civ is still so dependent on hold 4c CPU architectures that even with the power of Threadripper and Skylake-X, turns speeds will not improve to the degree they should. I can't remember where I read the logic behind that.

This probably means we won't see a dual Vega card. I think thats why the current Pro-Duo is fully under the Radeon Pro branding now and not the hybrid card the Fiji Pro Duo was.

We'll probably see a dual Vega card, but like the dual Polaris and dual Fiji cards it'll be marketed to developers, content creators, prosumers, etc.

This is everything I feel about dual GPU setups and why I have only ever ran, and running, one GPU in my rig, never more than that.

You got it backwards. That's what makes the APIs so significant. They are aimed at CPUs specifically. So by making the CPU more efficient they can get the same things done in less cycles which reduces overhead which then in turn improves performance. And since the CPU is using less resources you can have things in the background running, it could possibly help your stream go from a meh quality to a higher quality and still retain the performance on both ends.

Again these new APIs are aimed 90% towards the CPU. That's where everything starts. CPU and Memory are the most common limitations Devs have to optimize for. You want to be gpu limited, because that means you have a greater range of systems you can run the game on and simply upgrading the GPU will improve performance but it won't be limited by a bogged down CPU
