Here is an interesting post from Kyle Bennett at HardOCP regarding dual GPU setups:
This is an interesting quote from AMD on mGPU in DX12, OGL, and Vulkan. We were talking to AMD about CrossFire support in DOOM and AMD made this statement.
https://hardforum.com/threads/official-nvidia-geforce-gtx-1060-announcement-h.1904330/page-3I don’t believe there are plans to have mGPU enabled in OGL path for DOOM, and the Vulkan guys haven’t figured out what mGPU looks like yet.
Understand please that as games move to the newer APIs, the mGPU work has to be done by the developers, it’s not in the driver anymore…
