Hi, does anyone know about Catalina's support in X299 for dual AMD GPU? I have connected two Sapphire Nitro+ 580 4gb, the system recognizes them perfectly but the test bech programs do not use duality, Geekbench 4 and 5 recognize them separately, that is, to do the Metal or OpenCL test you must choose the Radeon 1 or Radeon 2, Heaven and Valley show no difference between 1 and 2 GPU. The only program that adds the power of the two GPUs is Luxmark 3.1. It would be interesting to be able to use the power of two GPUs, especially for After Fx and premiere. I want to trust Catalina because it is the system that implements the new Mac Pro 2019 and this computer announces the possibility of including several GPUs, greetings.
