I want to make a Crossfire setup. Does anyone know how well it scales in terms of performance?

I wanted to know percentage-wise how efficient or advantageous it would be to have a Crossfire setup. Specifically, I want to use 2 Radeon 7950’s. Any info would be great. Thanks!

It does not, Unreal Engine 4 does not support crossfire, nor SLI.

Through dont know yet about dx12 splitscreen rendering.

IF UE4 supports that, AND its enabled by default, I might return to use UE4.
