Does it also support automatic UEFI mode? I really want to disable the internal GPU so that I get a maximum performance of my eGPU. It seems that with GTX 770, I am not sensing any of the full performance of my GPU. I knew that with UEFI configuration I can turn off the internal GPU. Also should I just download the Optimus software to configure my display setting? I feel I am being really interested.
