Has anybody here had any success with multi-GPU between non-identical cards (like HD 7950/7970 or 280/280X) and the new 3DMark Time Spy DX12 benchmark? Or even with identical cards with GCN v1.0 architecture? On my setup with HD 7950 + HD 7970 CF, the benchmark only uses the master card regardless of whether Crossfire is enabled or disabled in the driver. Apparently the benchmark does not explicitly support multi-GPU configurations (unlike AotS) and leaves load balancing to the driver, which means CF should be enabled in the driver to work, but it is not working in my case. I'm not sure whether it is because the driver does not support this type of muti-GPU on GCN v1.0, or it is not working for me because my cards aren't identical. P.S. I am using Crimson v16.6.2.
