I thought Vulkan would come with Crossfire/SLI support
Did i miss something???

Selected Vulkan API, Updated GPU drivers, 0% gpu load on 2nd card :(

This game doesn't even need SLI support because you can max out the refresh rate on any monitor all the way up to 4k as long as your GPU is good enough.

Wow such a deep understanding of SLI you have.

SLI users would obviously benefit from Vulkan support.

Some of us use resolutions beyond 4K. Like triple screen 7680 x 1440.

Running game at 1.20x (DSR); my native resolution is 1920x1200 -- Vulkan (no sli support) gives me about 43 fps. But running the game in OGL with the same settings, I get about 57 to 60 fps (sli working). With this in mind, I would definitely appreciate Sli support for Vulkan!

Nope, I have an Asus PG279Q and 2 Titan X, I run Overwatch 165hz with G-Sync flawlessly, I hope this game support SLI of Vulkan.

With Crossfire On (2X390s) the game doesn't even start when I run it with Vulkan. It just stays in a black screen and I have to force-close it. In Openl GL it just uses one card. So much for Crossfire support...

That's not surprising since not 1 ID Softwares game support SLI or Crossfire. Am i wrong ?

It seems that it doesn't. The worst part is that it doesnt event fire up the game when I am using Vulkan. I have to go and disable CF from Catalyst and the re-run the game. I have a 1440p 144hz screen and I want to get more than 80fps. Is is that diffuclt for them to make it work??

I don't think the GPU market would want say, grabbing 2 x 280x cards in CF+Vulkan beating their best available single card, like the FuryX. GPUs and CPUs have been gimped for years, because software/APIs haven't caught up.

The engine simply doesn't support Multi-GPU. At the release of Idtech 5 it actually did support multi-GPU setups but it caused too much performance issues. This is when the developer team decided to patch out Crossfire/SLI support completely and instead dedicated the secondary card to CUDA processing.

Later patches further killed multi-GPU support by not even allowing the player to use "Texture Transcoding" option if the game detected you had a second GPU plugged in. You had to physically rip out that second card to enable the option.

That is how much this engine hates Multi-GPU solutions. Even today with the Idtech 6 it really doesn't support it. You might get some minor scaling if Alternate Frame Rendering is forced but it will never be perfect.

I dumped Crossfire as soon as I saw Doom didn't have multi-GPU support.
I'm not going back until every game supports it by default.

Same Story in Ashe of Singularity , i think it will take some time until full SLI Support Comes. Until that u only benefit from double ram bus.

Ok, first, nice necro.

Second, wut? What is a "double ram bus"? Are you talking about RAMBUS from the early Pentium 4 era? And if you are talking about pooled GPU memory, that is extremely rare, on not likely to ever catch on.

Ashes of the Singularity has the single best multi-GPU support of any game on the market, ever - even supporting multi-vendor setups, so again, not sure what you are talking about.

They don't use Ashes of the Singularity in multi-GPU benchmarks for no reasons.

Can anyone give me some RIMM 3200 running at 400MHZ ? RAMBUS ;)
