Sorry your not getting any replies, its probably because no one else has this issue or has a solution. These forums are user to user, ranting about Asus won't help, there not looking. You might look in the G750 forum they had Optimus too. I remember many issues and there may be some work arounds over there to help you out?

Sorry to hear you are having issues but like Clint said, this is a user forum that is sponsored by ASUS. They have some ASUS employess that poke their heads in from time to time but its not ASUS support. If you cant find someone else having the same issues I would suggest contacting support of the games you are having issues with and ASUS support directly.
I'm really sorry then and I apologize, I thought this was the ASUS support by the company. I'll check out https://www.asus.com/us/support/ cause according to the other threads I've read is that everything has to go through the Integrated CPU, which means my computer is highjacked by it.
I'm just surprised there isnt more uproaring about this as it limits your control as a user to be able to choose the best possible graphics engine, and instead being forced to use something that doesn't work very well compared to Nvidia.
If you have optimus, high chance you are stuck with it. You see, the Intel chip controls the output buffer. The nVidia chip renders it's workload and feeds it to the Intel IGP which displays it on the screen. So, if you disable Optimus, you won't have a display.
