I have an Alienware 15R3 with 1080maxQ, and an OMEN eGPU with a 2080ti. Is it possible to use any one of both as main display GPU and CUDA processor with the other also as a CUDA processor? GPUz recognizes both GPUs, but Nvidia Control Panel or applications like Octane only shows the main GPU. If not..is it possible if I use a Pci-E eGPU solution like the Beast? Thank you !!
