I have a MacBook Pro 15'' mid 2015 with M370X Dedicated GPU. I found when using Bootcamp to run Windows the battery drains quite fast because it only use dedicated GPU instead of Intel Iris Pro. Although I can use OS X, there are many programs I need to use in school that requires Windows (Visual Studio C++) so I have to switch between the two OS quite often.

After using rEFInd and enable spoof_os flag, I was able to enable both iGPU and dGPU at the same time but I cannot change brightness of the screen when using iGPU. I also found out that there is a problem when using iGPU that it will not wake up from sleep so I have to restart the entire system.

Has anyone has this problem?
