Graphic cards : 2 x RX 480's
Blender 2.8 beta v.2.80.74
Radeon ProRender Addon AMD 2.0.94
When I enable 2 graphic cards at the same time the render is slower than just enabling 1 card.
Render is also very slow and took 1 hour 20 minutes. I think code needs to be optimized.
Very slow compared to Cycles renderer.
