NVidia cards on 2018 15" MacBook Pro

Setup:
2018 15" MacBook Pro I7 8850H RP560X
Gigabyte Gaming Box GTX1070

I've been trying to get the GGB consistently working on the internal screen of my MacBook. In the last 2 weeks, I've been trying everyday and with just 3 times success out of 200. 

I've tried to:
disable Thunderbolt lanes;
use integrated graphics and then get eGPU connected;
hot plugging;
hot plugging during boot with timing;
enable TB lanes with eGPU connected to simulate hot plug;
reinstall W10 1803;
and use all four ports.

Non of the other ports are used during all the testing. All AMD and NVIDIA driver's got uninstalled and a fresh reinstall.

The 3 times I did got it working, was after 30 reboots and a perfectly timed plug with I don't know how many times the circles on the boot up screen has to do a 360. Then AMD dGPU and Nvidia eGPU worked perfectly in harmony <- exactly what I want consistently. 

I'm desperate for help, I want it to work. But after this, I'm on the verge of selling this thing. So frustrating.

If you have an exact solution or anything, you can also talk to me on discord: Buhtje#1420

What programs are you trying to accelerate? I've used a headless adapter to launch games on the eGPU and then use the shortcut winkey+shift+arrowkey to move it to the internal display.

@chinsteig, I've been trying GTA5, CSGO and Cities Skylines. I know these games are also CPU heavy, but nevertheless they should use the eGPU right?
And how do you mean a headless adapter? just a HDMI attached to nothing?

They should if you start them on a monitor using the eGPU or possible if you set them to using the graphics preference setting:  https://www.tenforums.com/tutorials/103965-set-preferred-gpu-apps-windows-10-a.html

Have you tried using an external monitor to test by starting a game on it and moving it to the internal in windowed mode?

oh I replied before I saw your edit, a headless HDMI adapter is just a plug, but it still tells the computer that a monitor is attached at a certain resolution. Most commonly used for remote pc's that don't really have a monitor attached but need to simulate something so you can remote in to use it.

@chinsteig headless adapters aren’t needed anymore for eGPU since as you pointed out, GPU preferences can be easily set in Windows.

@chinsteig, yes Ive tried on an external monitor. And that does work as expected, just booting up the macbook with eGPU attached. But this would disable my internal macbook screen, since the macbook bootup process found an eGPU. Plugging in the eGPU when Windows is booted, will cause an ks.sys error, which i dont really understand what it does.

My goal is to get the eGPU to work consistently through bootups with or without hot plugs on the internal screen. Only the internal screen, for on the go work. 

Which eGPU do you use?

This is a very good setup. It works like charm almost out of the box.

@oliverb, I dont seem to get it why it doesnt for me... I've got such a headache from it. How do you do it to get the AGB connected consistently only on internal screen? I get the blue screen of death plugging in too late, and only HDMI output if I plug in too early.

Did you read my Guide?
The nVidia section is very small because it's so easy.
