Hi all,
Oh absolutely. All you have to do is use the default setting and remove the Nvidiaweb drivers or any reference to the Nvida settings. Follow other Asus Prime guides that use the Intel chip GPU. That should work.
That's a bit odd. To enable the TB3 card to work, the first you need to do is have a working Windows 10 setup so that you can update the TB3 firmware on the card. No matter when you bought the card, the update is essential for it to work 100% in OSX. As my guide stated you need to upload the Asus TB3 firmware updates in numerical order, so that it activates properly (and make sure it is detected in the Asus TB3 properties in Windows). The second is that the PCI card should sit on the 3rd slot in the system (with the relevant wire plugged into the motherboard) for most of the functions to activate.
