EDIT:

I tinkered further, and I am getting much better performance now. Rescinding this post

You will surely find out how to make you eGPU setup work decently, don't worry! Smile

The only problem, i see increasing people keeping buying high end video adapters coming on this forum, like 1070/1080/Ti/Txp on laptops and external adapters that are not suited for it, maybe the apple customers do not known their own apple hardware before buy high end video adapters.

Unfortunately i don't think this trend will change, so you are not the 1st, nor be the last to complain about perfs, at least if you know the real perfs of a 1080, obviously. If you do not know it is ok, but if you know i would be much more than disappointed.

So 1st of all, update your node firmware, you will already get decent performances. Then look for the automated script to load you eGPU under mac or the bootcamp guide for windows!

Thanks for the reply. 

I have already successfully updated the node's firmware using the tool on windows. 

I certainly expected better performance- its nearly a top of the line MBP, so the CPU should have plenty of horsepower. I certainly thought adding a 1080ti would perform better. I can imagine that CS:GO isn't really optimized on mac... I am hoping something else is causing that game to not utilize the 1080ti, which would explain the poor performance. 

Regarding the bootcamp guide- I followed the instructions, made the USB stick bootable EFI drive, but got stuck at the step that instructs me to set the boot drive to my Windows drive in macOS System Prefs Boot Drive. When I click my Windows drive in that System Pref, it says it can't select that drive- "The bless tool was unable to set the current boot disk". 

If I then boot off the USB efi disk, macOS just launches after that. Seems understandable that I need to set the windows drive as the default boot disk, but I can't seem to do that.

Forgot to note- I also successfully used the automated script to load eGPU under mac. That is how I was first able to get macOS to see the card. It was after that when I ran my test and saw the meager performance.

I understand your frustration. What we all need to keep in mind is that Apple never announced eGPU is a feature of its Mac lineup. This is all possible through hacks. Some configurations are easier to get going than others.

The late 2016 15" MacBook Pro will need DSDT override to work with eGPU in Windows. There are several approaches to fix error 12. Nando has done a lot of documenting to help eGPU Mac users. Take a look at this thread.

Thanks for the tip! I will look into the DSDT override
I haven't actually seen error 12 myself yet- I was seeing an error 43 in windows, which was suggested to be driver related. But I had not done the DSDT override so I will try that next.

Well, i will be honest with you, there is no way to recover the performance you expect, if i got the level of hardware skill you got by your witting. You will simply not reach that forgot it, but on the other hand, even if not fully portable, the setup have a decent interest since you can play everywhere on every screen you will encounter on the road, max settings. On your way if you move a lot, this is may case and obviously i have low end setup for the reason you just stated above, people are astonished when you are working, then you finish, take out your eGPU, lunch a game for relax. Smile

For me an eGPU setup is like a console, for my gaming preferences/habit, i couldn't see it otherwise, even the very good performances it deliver on high end setup. For me it is simply not enough. It is wrong to get the habit playing on highly overclocked, water cooled rigs, i know. ^^

So i hope simply saying this: On 1080p even an i7 7700K@5.2Ghz still +/- bottleneck a 1080Ti! Obviously taking account of all hardware behind!!!!!!!!!!!!!!!!!

Hope this simple sentence is enough to redirect all the apple customers to think about and wisely put aside the 1080 series on an eGPU setup, and focus mainly on 1060/1070.

That said, i know people would say it is maybe not enough for 4k, and you still get better perfs with a 1080 on an eGPU setup. I will simply answer it is ok if you can play with frame drops occurring when the average is only 40/60fps, with limited bandwidth!!

 The error43 is often related to a driver, adapter initialization/power, hot plug support problem. Theoretically you should, like wisely said Theitsage, an error12 instead.

I wouldn't blame the hardware just yet. Either there's a software configuration problem or CS:GO just sucks on Mac OS (quick googling says that's probably the case).

 

Under Windows I get ~180FPS in CS:GO at 1080P with max settings using an RX 480 and a 5 year old Sandy Bridge i7. That's even with a pathetic mPCIe x1 2.0 link.

Again i repeat maybe myself, but i invite you to check the reviews and youtube ingame videos about 1080Ti performances, we are not speaking about CS:Go, i didn't even bother to consider the CS:GO as a game to test with.

We are not here to blame the hardware or anyone, i just want to remember to buy carefully, to not be deceived from the performances you expect.

Because on overall eGPU setup works wonderfully, after you spent a bit of time to understand and tweak a bit, it is true.

Understand a bit the level of hardware you can couple with, even a 3k dollar macbook, could compete with the raw performances of a 1k dollar computer build, needed to allow the 1080/1080Ti/Xp to perform as they should.

At the end it depend like i said, your gaming habit, if you are a casual gamer everything is ok, if you are a power gamer and not fully into hardware stuff, it is normal for a random power gamer customer to be deceived by the 1080 eGPU performances at first!

Thanks for the input, Plastixx. 
I was hoping I could expect better result with CS:GO on Windows- I can certainly understand that CS:GO runs better on Windows.. my experience with it on mac has certainly been buggy.
I'll just have to solve the puzzle of getting the egpu working on Windows.
