Instal Windows... Nvidia drivers are crap in macOS. Games run a lot better in W10.

That's a less than helpful answer.

Why is that "less than helpful"? The OP wants better gaming performance, games run far better in Windows. By installing Windows you can get the best of both worlds - a macOS environment for everyday usage and when you want to game switch to Windows for better eGPU support (Windows manages all GPUs at a system level)?

Despirte "official support" for eGPUs in macOS in far more use cases Windows and eGPUS's "just work".

GTX1060 + AKiTiO Thunder3 + Win10
GTX1070 + Sonnet Breakaway Box + Win10
GTX1070 + Razer Core V1 + Win10
Vega 56 + Razer Core V1 + macOS + Win10
Vega 56 + Mantiz Venus + macOS + W10

I'm going to give Windows a shot, following the directions on getting Windows to work on a non-MBR bootcamp partition. Will post back findings.

Maybe try with close the lid? I think the other folks were testing with mac mini. What is your OSX version?

OMG! I've finally found someone who had/has the same problem I do.

I know this is an old thread but OP, did you ever figure out what the issue was?

I'm running a thunderbolt 2 equipped MacBook Pro with an RX580 eGPU.
Gaming performance is horrible.  I have the same problem that you described where it also doesn't seem to matter how much you lower the settings, the games still encounter massive frame drops and other undesirable performance problems.  I'm in a position where I can't dual boot windows just to play games so I would like to get this to work in Mac OS.

@ocaptain12 This is not true. He is right- Newer games are hardly playable in MacOSX.

You playing Fortnite and League of Legends in MacOsx?! Is it a native Mac game or some Wine-wrapped game? Steam?

Has anyone ever figured out what the issue was? I'm seeing the same performance hiccups as OP and @Effloretron but with a Radeon VII. The full setup is:

MacBook Pro (15-inch, 2018)
2.9 GHz Intel Core i9
32 GB 2400 MHz DDR4
Intel UHD Graphics 630 1536 MB

Razer Core X Chroma + AMD Radeon VII
LG 27ud88-W

Everything connected with stock Razer TB and LG DisplayPort cables.

The same setup works butter smooth with a 2016 Dell Precision M5510 but if plug it into the Macbook Pro (on macOS), I'm getting the same behavior as others: games seem to run at perfect FPS for a couple seconds, and then get very choppy for 2-3 secs (I would say it drops to 5-15 FPS).

It gets a little better if I change to the monitor resolution to Default for Display. Which is surprising given that the game is run in real fullscreen/nonwindowed mode. But the frame rates are still unplayably choppy. A better way to explain it is that the FPS is generally very good, but every 2-5 seconds it drops several frames.

So I just got it under control, although I don't know for how long. What did the trick for me (again, we're talking macOS only):
0. I have previously switched the monitor resolution to Default for Display. But it did not solve the problems on its own.
1. Installed Rise of the Tomb Raider (if that makes any sense...).
2. Disabled USB Overdrive.
3. Disabled Automatic graphics switching in Energy Saver.

I tried to pinpoint which one of those helped but at this point everything is running smoothly even if I reenable USB Overdrive and Automatic graphics switching and restart. I understand that it makes little sense, but those steps are what solved the problem, at least temporarily, after three days of trying.

After some further testing I can confirm that the problem was cased by using a scaled resolution. This is surprising because exclusive fullscreen mode did not solve the problem in any of the games that I tested.
