From reading that, Ark supports SLI/Crossfire but the GPU drivers need to enable it.

[LBXZero]

The game uses Unreal Engine 4. UE4 has incompatibilities with AFR mode, which is the only mode that SLI uses, and the mode that Crossfire has focused on for years.

The only way Ark will support anything multi-GPU or DX12 or Vulkan is if Epic updates UE4 to officially support them.

There are means to override defaults and have Crossfire and SLI work. Don't have high expectations.

Unreal Engine 4.15
"The engine now supports AFR rendering for Nvidia SLI configurations to provide superior performance when multiple graphics cards are detected. The largest improvement comes from the renderer copying inter-frame dependencies between GPUs as early as possible. Developers will need to work with NVIDIA to test their game and to have it automatically switched over to AFR where appropriate."

No idea what AMD are doing about this and I assume Ark uses this version of the engine?

Not sure if AMD has released crossfire drivers for ARK, but nVidia has released SLI drivers just prior to ARK's "launch".
