@eightarmedpet I have been using a late 2016 15" MacBook Pro with Thunderbolt Control Center and there's no noticeable difference in terms of Thunderbolt detection through EFI boot loader. This piece of software is helpful when we need to flash the Thunderbolt 3 firmware of the enclosure. Not very useful for most Mac users in Boot Camp otherwise. Also worth noting is that I heard Apple may release a Thunderbolt firmware tool for macOS.
