This is the first post I've seen for the 2012 MBP 15" that used the eGPU Setup program and first implementation I've seen of it. How much of a sure fire way is using "eGPU Setup" to get a eGPU working easily? The reason I am confused is that the website for eGPU Setup's copyright was 2012... seems like pretty old software with not much explanation on their site. I guess my question is, if it is so "easy" to install the eGPU on windows using this paid tool, and have it fully implemented into your Bootcamp partition, why are others not using this method to install their eGPU's on Windows 10 and relying on methods that limit their abilities to use the eGPU (i.e. no internal display, specific boot up orders, etc.)? Is your method more future proof or reliable compared to LukeHero's method for example (which requires a EFI Install of Windows): http://forum.techinferno.com/implementation-guides-apple/10438-2012-15-mbpr-gt650m-gtx970%4010gbps-tb1-akitio-thunder2-win8-1-%5Blukehero%5D.html
