AMD has released their latest Radeon Software Crimson ReLive Edition 17.9.2 drivers, with a surprise feature: 2-way multi-GPU support for Radeon RX Vega graphics card.
CrossFire support isn't center focus for AMD, something that the company has been very forward with for a while now. They will be pushing out multi-GPU support for their Radeon graphics cards in the future, but they're definitely pulling out of sheer beasty multi-GPU gaming PC rigs.
However, the new 17.9.2 drivers only support 2-way CF setups, with 3- and 4-way RX Vega setups simply not possible right now. I'm just installing the new drivers on my Ryzen Threadripper 1950X machine, with my 2 x RX Vega graphics cards and 8K display... we'll have results of RX Vega 64 CF over the weekend.
