Fusion rendering only on CPU

From the deliver page and from the fusion page I cannot get Fusion to render using the GPUs. Its all happening on the CPU which means it takes much much longer. And yes, the option to use fusion only on CPU is unchecked in the preferences. So Im not sure what else to make of this.

Didn't change any settings, but now Fusion is using 1 GPU, but not both. Is it best to do SLI for Resolve or not to?

Davinci Resolve doesn't use SLI. It uses CUDA and OpenCL which support multiple GPUs. I am not sure but running GPUs in SLI may interfere with Davinci Resolve's ability to use multiple GPUs. Also a believe multiple GPUs are only supported in the studio version of Resolve. http://documents.blackmagicdesign.com/DaVinciResolve/20180404-10399d/DaVinci_Resolve_15_Feature_Comparison.pdf
