Razer Blade 2017 Thunderbolt 3 using optimus?

I've been wanting to preorder the oculus rift s. The downside is that it uses a display port which the razer blade 2017 does not have, which means I would have to use an adapter. Now the thing is there is no hdmi to dp adapter. But there is a thunderbolt 3 to dp adapter. Which is exactly what i need, except the thunderbolt 3 port on the razer is wired to the igpu. I have been researching and have seen multiple people saying that "The 1060 will handle the game rendering, and will communicate the output to the intel graphics card, which will output on thunderbolt" Now this is great news, but some others are reporting their gaming on external monitors are not taking advantage of the 1060. So please someone confirm with me asap as I am planning to preorder the oculus rift s by tomorrow.
